Title: Electronic gaming platform having shared and private screens

Description:
RELATED APPLICATIONS 
     This application is a divisional of U.S. patent application Ser. No. 12/612,637, filed on Nov. 4, 2009, now U.S. Pat. No. 8,226,476 and which claims priority benefit from U.S. Provisional Patent Application Ser. No. 61/193,189, filed on Nov. 4, 2008. 
    
    
     BACKGROUND 
     1. Field of the Invention 
     This invention relates generally to a multi-player, multi-screens digital gaming platform for enabling digitally playing a multi-player social games in multiple screens possibly running on different hardware platforms. 
     The use of “social games” refers to inter personal social games including digital versions of traditional and new board, card, dice, and similar games. 
     2. Related Arts 
     Electronic augmentation of traditional board games has been an active area of research and product development, as electronic board games offer certain additional advantages without affecting, and often enhancing, the fundamental enjoyment factors of the traditional games. Some of the advantages include enhanced player interaction support, compact board footprint for playing and storing the game, ability to load multiple games on the same board, no loose game-pieces to be lost, easy on-demand access to digitally stored information regarding game rules and strategy suggestions, real-time game status updates, etc. These advantages are applicable to both single-player board games, and multi-player board games. 
     Traditional multi-player board and card games, such as, Scrabble, Monopoly, Risk, Chess, Texas Hold&#39;em etc., and more recent designer board games, such as, Settlers of Catan, Apples to Apples, Uno etc., promote live social interaction among two or more players. The social interaction experience is different from the experience of playing computer or electronic games designed to enable a single player to interact with a machine and/or Internet players. Often a collaborative/competitive multi-player board game experience is more desired by the players than the isolation typically associated with a computer/electronic game. 
     Therefore, what is needed is a crossover gaming platform that offers the merits of conventional games, while adding digital features that enrich the game-playing experience, as well as provide practical conveniences, such as versatility and ease of storage. 
     SUMMARY 
     The following summary is included in order to provide a basic understanding of some aspects and features of the invention. This summary is not an extensive overview of the invention and as such it is not intended to particularly identify key or critical elements of the invention or to delineate the scope of the invention. Its sole purpose is to present some concepts of the invention in a simplified form as a prelude to the more detailed description that is presented below. 
     The present application discloses recommended processes and systems for the implementation of multi players, multi screens gaming system. The gaming system is suitable for playing locally traditional and new board, card, dice, and similar social games, but it can be applied for other type of games and social applications. 
     Various embodiments of the gaming system involve hardware and software implementations. The hardware implementation includes board and terminal components, which may be proprietary or conventional. The software implementation includes board and terminal subsystems. The software implementation may also include dedicated user interface and software development services. The software implementation is transparent to the hardware deployments; therefore the software implementation requires OS specific adaptation. 
     Hardware 
     “Board” 
     The purpose of the gaming system “Board” is to display the shared part of the game (e.g. the Monopoly board). The “Board” can be horizontal and controlled by touch gestures (similar to Tablet) or vertical/frontal and controlled by custom controller. Multiple boards can be assembled together physically or logically by the “gaming system software” (see description below) to provide bigger shared area. The “Board” can be proprietary or conventional horizontal or frontal display including tablet, pc monitor, TV monitor, etc. In case the “Board” hardware is “TV”, it requires attached processing unit that can run standard OS and wireless connectivity to the internet and locally to communicate with the players terminals. Such processing unit can be PC, Media Center (e.g. Apple TV™), Game Console (e.g. Sony PlayStation™, Microsoft XBOX™, or Nintendo Wii™), Set top box (e.g. Tivo™), or embedded unit on the TV itself. 
     “Terminal” 
     The purpose of the gaming system “Terminal” is to display private parts of the game (e.g. the Scrabble tiles or Texas Hold&#39;em cards), to perform private activities (e.g. consulting English dictionary in Scrabble, taking notes in the Clue game, or Simulate few chess moves), and to control frontal “Boards”. The scope of the invention is not limited by the number of game terminals. Also, any type of smart personal device with a display, such as, a smart phone (e.g. iPhone™), a PDA (e.g. iPod Touch™), a personal media player (e.g. Nintendo DS™), etc., may be used as the game terminal, as long as the device is running the “Terminal subsystem software” (sometimes also referred to as “augmentation layer”) that is described below. 
     Dedicated Hardware Design 
     The purpose of dedicated hardware is to provide optimized experience of digital board and user terminals in dimensions and usability. The dedicated hardware is portable and packages together in compact way at least 1 board and 4 terminals. The dedicated hardware may include few boards and physical connectors to attach them. The physical connectors may be used to exchange data and power. In case of multiple boards, some of the boards may be dumb, used for surface extension (both display and inputs), and are fully controlled by their hosting board. The dedicated hardware supports single charging point of all the system components. 
     Special Purpose Hardware Gadgets 
     The gaming system may include special purpose hardware gadgets that can communicate their outcome over wireless communication and impact the game play. Examples of such gadgets are physical dice, game pieces, sand clock, or “live” avatar that has unique role in the game. 
     Software 
     The “gaming system software” is in essence abstract operating system that consists of “Board subsystem” and “Terminal subsystem”, runs on variety of hardware platforms, and implements hardware agnostic gaming services. 
     Objects Exchange 
     The “gaming system software” provides seamless movement of digital objects between the system screens, including board-to-board, board-to-terminal, terminal-to-board, and terminal-to-terminal. The objects exchange depends on the game play rules. Objects can move as is (e.g. Monopoly money) or follow some transformation rule (e.g. flip Scrabble tile, show Poker card). Objects exchange can trigger some game rule (e.g. decide on the winner in Card games). Object exchange can create unique experience like dice shake on the “Terminal” (using the accelerometer) that virtually continues on the “Board” taking into account the magnitude and direction of force applied by the user action. Example of game objects are tiles, cards, chips, money, drawings, avatars, etc. 
     “Board Subsystem” 
     The “Board subsystem” provides system administration, players management, and game management services. The “Board subsystem” loads games from local and web game repositories. The “Board subsystem” enforces the user rights to the games and manages the accounting between the user and games providers. The “Board subsystem” manages intelligent cache of game assets and automatic updates of game features. The “Board subsystem” displays the shared part of the games and handles the game play. The “Board subsystem” provides set of gestures and features to enrich the game play, including drag-and-drop, flip an object, spin an object, rotates the board to the user side (may be applied automatically as part of the game play), etc. The “Board subsystem” utilizes the full screen for the game play and enables to access the system navigation and configuration functions through floating dashboard that can be launched anytime from pre-defined hot key (e.g. &lt;Esc&gt;) or hot spot on the game board, e.g. the bottom left corner. The “Board subsystem” handles the communication and assets exchange with the players&#39; terminals and optionally with additional boards. The “Board subsystem” manages list of permanents and ad-hoc players including personal preferences (name, avatar, color, etc.), favorite games, and statistics (for each game: # of plays, wins, looses, points, etc.). The player personalized information may be imported automatically in case of ad-hoc players with smart phones and PDAs. The “Board subsystem” publishes its availability and therefore can be discovered by other “Board subsystems” and “Terminal subsystems”. The other “party” requests to join the board (in case of “Terminal”) or share the board display (in case of other “Board”), and the board user needs to approve it. That process is necessary in case of multiple boards&#39; environment like video arcades, game board Café&#39;, etc. 
     The “Board subsystem” is the center of the game system and provides software services to its satellites “Terminal subsystems” including necessary game assets (the “Terminal subsystem” is not dealing with games downloads or licensing), list of known players (for the link of player to terminal), list of available colors (as part of the player personalization or game setup process), list of other terminals (to enable terminal-to-terminal communication) etc. 
     Multiple Boards 
     The “Board subsystem” discovers automatically other “Board subsystems” that it can utilizes their display area. The “Board subsystem” requires the approval of the other “Board subsystems” to utilize their display area. In case that multiple “Board subsystems” agree to share resources, the “Board subsystem” that starts a game, take control on others and handle the game flow. 
     Multiple “Board subsystems” can work in few configurations, 1) create bigger view of the same skin where each “Board subsystem” display and get inputs on part of the display, 2) enable multiple boards&#39; games, e.g. playing few Monopoly boards and create expanded game play, 3) enable peer-to-peer boards games, where each player enjoy full board experience in games like Battleships or Stratego, 4) create exact duplication of the game board to support many players experience, maybe in different locations, etc. 
     Positioning Process 
     The “Board subsystem” manages the players&#39; position on the board. The process may start with the collection of players with terminals or the definition of current players on the board (e.g. in case of Chess the terminal is not mandatory). Players positioning view shows a “symbol” for each player and let the users drag their symbols to their preferred side on the board. The process supports any number of players that can share the same side. The above process defines the area in which the player objects will be exchanged with the board, e.g. when he/she drop tiles from his terminal to the board, or drags cards from the board to his terminal. 
     In many games, the “Board subsystem” manages the turn of the players. When the turn is well defined, multiple players can share the entire side for drag-and-drop actions (vs. using fraction of the side depends on the number of players). 
     The above process is necessary before any game starts and can be altered during the game. The defined positions and drag-and-drop areas may be viewed during the game as names, colors, avatars, and/or players pictures as additional “players&#39; layer” on top of the board area and may have different variants on different games. 
     In some games, when it&#39;s important that all players will know each other assets/status (e.g. chips in Poker, cash in Monopoly, or score in many games), the “players&#39; layer” may show in addition to their names, colors etc., their assets/status. 
     Alternatively, the above players&#39; details can be defined as “players&#39; box” that can be dragged to any area in the board and thereafter used as the players&#39; “gate” to the board (e.g. in Poker it makes more sense to position the “players&#39; box” adjacent to the table vs. the frame of the display). 
     “Terminal subsystem” 
     The “Terminal subsystem” searches for available “Boards” in the area and enables the user to connect to one or few of them. The “Terminal subsystem” enables the user to personalize his name, symbol, color, and position on the “Board”. The “Terminal subsystem” receives the game assets from the “Board subsystem”. The “Terminal subsystem” displays the player private data (e.g. Tiles in Scrabble or Poker Cards). The “Terminal subsystem” provides private actions like browsing electronic dictionary, game rules, or potential game strategies. For example, it enables the user to take private notes related to the game (e.g. in the Clue game). In another example, it enables the user to simulate privately potential game steps (e.g. in Chess) without the steps being implemented on the actual game played. As the game progresses, the user may activate one or more of the simulated moves, so that they are actually performed in the game played. Alternatively, the user may change the simulated moves according to new moves that were actually enacted in the game played. The simulated moves can be saved in the memory, e.g., RAM, and the processor can enable the user to switch between “real” game view and “simulated” game view. The “Terminal subsystem” exchanges game objects with the board or other terminals. The “Terminal subsystem” enables in some games to share private information with other players&#39; terminals, either by sharing the entire view or exchanging individual objects and widgets. The “Terminal subsystem” supports touch gestures and hand writing; the hand writing drawings and lists can be exchanged as other game objects. 
     Remote Control 
     The “Terminal subsystem” may include remote mouse and custom controller of the board view. The custom controller can be generic by sharing the entire view (like Webex™) or game oriented by exchanging the game gestures and actions (e.g. moving a tile on the controller will send “move tile action” to move the same tile on the shared board). To complete the experience, the “Board subsystem” needs to inform the “Terminal subsystem” about changes on the physical board, and the “Terminal subsystem” in exchange should update its user miniature view of the board. The custom controller support zoom and board shift to access easily any part of the bigger board. The terminal controller supports zoom and board shift to easily access any part of the main board. It also supports store and forward function that enables the user to prepare the next move privately before sending it to the main board. When the terminal is set for a view of the main bard, its processor may constantly synchronize the user miniature view of the main board with the main board subsystem.

     DETAIL DESCRIPTION 
     Various embodiments of electronic gaming systems, including the relevant hardware and software, are disclosed. In general, the disclosed system can be implemented on dedicated, specifically designed hardware, on commonly available hardware, or on mixture of dedicated and commonly available hardware. In this sense, the invention provides an orchestration system that manages communications and processes among the various hardware pieces which form the multi-screens aspect of the multi-player gaming system. The orchestration system can be implemented purely in software running on, e.g., general purpose computers, video game consoles, PDA&#39;s etc., (when no dedicated hardware is used), or in combination of software and dedicated hardware. The inventive system introduces an augmentation layer that enables required transactions among the various screen units. Therefore, the inventive system can be conceptualized as an augmentation layer running on top of the native OS, and a game application running on top of the augmentation layer. In this respect, the augmentation layer may be generic and indifferent to the specific game being played. In addition to features described in details herein, this implementation also enables the system to operate on various platforms, wherein each platform is running a different operating systems (OS). Also, in certain implementation a generic core enables certain generic actions required for all games. Once a player selects a game, the core takes appropriate actions to load elements required for the specifically selected game. 
     According to certain aspects of the invention, the system may be implemented as a portable electronic gaming system allowing a plurality of players to play a game on a plurality of screens. When the system is implemented as a dedicated hardware, the system comprises a game board having a main display screen for displaying a portion of the game layout that is shared by the plurality of players, and a plurality of personal game terminals, each personal game terminal assigned to a respective player and having an auxiliary display screen for displaying a portion of the game layout that is associated with the respective player. The system enables communication between the main display and the personal game terminals, and optionally also among the game terminals directly. The system also enables seamlessly transferring digitized game objects between the respective auxiliary display screens and the main display screen, or among the auxiliary display screens, as triggered by, e.g., a game step or in response to touch-based interactive inputs received from the plurality of players. The system may also transfer or initiate coded rules associated with the transferred digitized game objects. For example, the rules can indicate where on the screen the digitized game object should appear, at what size should it be displayed, special animation that should accompany the transfer of the digitized game object, etc. 
     According to another aspect of the invention, the electronic gaming system can also communicate with and implement a game using conventional hardware. For example, iPod™, iPhones™, PDA&#39;s, smart phones, etc., (generally referred to herein as “smart device”) can serve as the personal game terminals and communicate with the dedicated hardware or other types of conventional hardware (e.g., Wii™, X-Box™, etc.). This is enabled, at least in part, by the inventive augmentation layer that enables transactions among hardware running on different platforms, and by the game application operating over the augmentation layer. As before, this arrangement allows for digitized game objects to move seamlessly among the plurality of personal game terminals and the main board in response to game rules/steps or interactive inputs received from the individual players. 
     According to yet another aspect of the invention, the gaming system may utilize a conventional display, such as a plasma or LCD television or monitor as the main screen, and utilizes dedicate, conventional, or a mix of dedicated and conventional personal game terminals. 
       FIG. 1  illustrates various possible implementations of the inventive multi-screen, multi-player gaming system. Elements that can function as a user terminal are indicated by (T), while elements that can function as the main board or console are indicated by (B). Shown at  100  is a system that is made of dedicated hardware, i.e., dedicated gaming board  102  and dedicated terminals  104 . The board  102  and terminals  102  can function as a complete gaming system and are capable of communicating among each other. On the other hand, a conventional smart phone or a portable gaming system can also be used as user terminals and communicate with any of the boards shown in  FIG. 1 , provided that these terminals run the software modules described below. Similarly, a conventional PC, Tablet PC, set-top box, or a TV (either a “smart” TV or a regular TV functioning as a monitor and coupled to a set-top box, PC, conventional gaming console, etc.), may function as the main board, provided that these terminals run the software modules described below. Communication can be provided between and among any of the terminals and main board shown in  FIG. 1 . 
     Other embodiments and advantages of the present invention are discussed in the subsequent detailed description section. 
     Overview 
     The present application discloses a novel digitally-enhanced gaming platform for playing existing and new social games. A typical gaming system comprises a main game display module and may have one or more personal game terminals having auxiliary game display modules and communicating with the main game display module. The personal game terminals may also communicate with each other. Various personal game terminals are enabled to exchange game-related information with other modules and to seamlessly move digitized game-specific pieces/objects (e.g., cards, tokens, tiles etc.) to other modules or to the main game display. 
     In certain embodiments, games can be played with shared public information displayed on the main game display module, and individual public/private information displayed on the auxiliary game display modules. In other embodiments, there is no main game display module, but a plurality of inter-communicating auxiliary game display modules are assigned to individual players. 
     The personal game terminals may be handheld devices, such as, smart phones, personal digital assistants (PDA), or dedicated personal game terminals assigned to individual players. The main game display module may be a portable dedicated digital game board, or may be part of an existing appliance, such as, a television screen or computer monitor coupled to a computer or game console (such as Nintendo Wii or Microsoft Xbox game consoles) running an appropriate gaming software. The main game display module may have other configurations, such as, a touch-screen-enabled tablet PC, or a laptop computer with a keypad, touchpad, trackball, etc. The digital board may be designed to be folded for portability and ease of storage. The main game display module may be a combination of one or more existing appliances and a dedicated digital game board. 
     The main game display module may be a single display unit, or a plurality of display units that can be coupled to each other. Coupling a plurality of display units to form the main game display module has the additional advantage of creating increased shared playing area that can accommodate more visual information related to the game. The plurality of display units may be physically pre-attached to each other by some fastening mechanism, such as, a hinge, a flexible backing tape, etc., or they may be removably attachable to each other, as required. When the plurality of display units are aligned together, the system automatically identifies the new structure and applies the game layout over the combined display units, forming a larger unified game surface. In one embodiment, a plurality of removably attachable display units can be used in at least the following ways: 1) two or more display units are used for public display, wherein digital game pieces can be seamlessly moved from one public screen to another, e.g., player finishes the game track on one public screens and continues to play on a second public screen, 2) one or more display units are combined to form a bigger display module displaying the shared playing area; 3) one or more display units are used individually as auxiliary game display modules, where the game does not necessarily need a shared playing area; 4) two or more screens that are duplicate of each other—this is especially beneficial for games played in teams, wherein each team receives one public screen having the same graphics as on the other public screens; 5) two or more screens that are calculated-duplicate of each other, i.e., part is duplicate and part is not according to certain game rules—this, for example, can be implemented for playing Submarines, where part of the screen is duplicated, but other part is hidden; etc. 
     A processor within the main display unit can implement a positioning process. According to this process, the processor of the main unit maps the physical location of every game unit, i.e., public and personal game units, with respect to the main unit and other units. To illustrate, the processor can utilize a North-South, East-West grid centered at the center of the main public screen. If four players with four personal game units are seated around the main screen, then the processor identifies each personal unit and maps them according to the North-South, East-West grid. To enable this mapping, the processor establishes a communication protocol to recognize each personalized game unit and to approve-disapprove its joining the game. If the personal unit was approved to join the game, the unit establishes a physical location for that unit. For example, the processor may display a symbol identifying this unit at a certain coordinate on the main screen. When the user of that unit is actually seated in a different location or would like to move to a different location, the user can “drag” the symbol on the main screen to a different location. 
     The above process is not limited to 4 players and supports the allocation of few players to the same side with virtual separation between them (e.g. Half-Half). Furthermore, the same process is applicable without physical game units, in case the entire game play is happening on the same board (e.g. Chess). In such case, virtual image/avatar of each player is used to define his/her position around the board. 
     As mentioned above, digital game pieces can be seamlessly moved among the various private and public screens. For example, a user may move a game piece, e.g., a card, from his personal unit to the main unit using, e.g., an assigned button, softkey, or hand gesture. In this respect, the digital game pieces can be grouped into two type of digital game pieces: “dumb” game pieces, i.e., digital game pieces that have basically only graphical representation but no function, e.g., cards, chess game pieces, etc., and active or “intelligent” pieces, which have internal function, akin to a widget or applet, e.g., die, warrior, etc. Additionally, when a game piece is transferred from one terminal to another, whether personal or public, a rule set is implemented to that specific transfer. The rule set may include, for example, the location for displaying the object on the transferee screen (for example, at an indicated place on the public main game board, at a location closest to the player transferring the piece, etc.), the size of the object to display (for example, enlarge or reduce depending if moving from a small to large screen or vice versa), any motion of the piece (e.g., if moving a covered card from main screen to private screen, flip the card to reveal its face), enact action per game rule, (e.g., when moving money in Monopoly from private screen to bank at public screen, action can be activated, e.g., game piece goes out of jail if payment was made to get out of jail), activate audio corresponding to the game piece, etc. 
     Combining the positioning concept with the seamless motion of game pieces, according to one embodiment, during the positioning process the processor displays “gates” on the main screen for each player. The gates may be displayed graphically in any shape or form, as long as each gate is identified as corresponding to a personal unit or player participating in the game. Then, when a digital game piece is moved from the public screen to a personal screen, it is graphically moved on the public screen towards the gate corresponding to that specific personal unit. The reverse is also true: when a user moves a game piece from a personal unit onto the public screen, the game piece “enters” the public screen through the gate associated with that particular personal unit. 
     Combining the above with the natural game turns enables the players to use their entire side to exchange objects with the board, as compared with sharing the side with other players wherein each player gets a smaller defined gate. 
     Various Playing Configurations 
     The gaming system components can be used in different playing configurations allowing the player(s) to play different type of games. 
     Examples of different playing configurations are discussed below with specific game examples for each. In these examples, without limiting the scope of the invention, a dedicated digital game board is recited as the main game display module, and dedicated game terminals are recited as the auxiliary game display modules, for illustrative purposes. 
     Single-Unit or Multi-Unit Game Board with No Personal Game Terminal 
     In this configuration, the game is played using only one game board, where one or more players play a game using a touch screen (or keypad, trackball, joystick, touchpad etc.) on the game board. The game board displays shared “public” playing area. The game board may be a single display unit. Alternatively, as discussed before, two or more display units may be combined together to expand the display area of the game board. Examples for games suitable for this configuration are Snakes and Ladders, Memory game, Chess etc. 
     In an extension of this configuration, multiple shared “public” game boards may be used. Examples of this configuration are strategy games like “the Settlers of Catan”. Since a large public playing surface is often required, a multi-unit game board is often suitable for this configuration and game pieces may be moved seamlessly from one main board on one display unit to another main board on a second display unit. 
     Single-Unit or Multi-Unit Game Board with Personal Game Terminals 
     In this typical configuration, the single-unit or multi-unit game board is used for the game&#39;s shared “public” playing area, which all the players can see and use, and the personal game terminals are used for each player&#39;s personal playing area. The “personal” playing area may be “public”, i.e., visible to other players, or may be “private”, i.e., exposed only to a specific player and hidden from the other players. Personal “private” playing area may be selectively accessible by collaborators, but not by the competitors. The personal game terminals exchange information with the game board. 
     Examples for games suitable for this configuration are Monopoly, where the terminals are visible to all the players, yet hold the respective player&#39;s properties information (such as the money stack of a player), and Scrabble, where the terminals hold the respective player&#39;s letter tiles and this information is hidden from the rest of the players, and many card games, where the terminals hold the respective player&#39;s private cards. 
     Personal game terminals may be used for a variety of functions, including, but not limited to, privately browsing game rules, consulting game strategies from available suggestions, consulting references (e.g., looking up a dictionary in a Scrabble game), taking private notes (e.g. in the Clue game), planning privately the next game steps, and optionally, for remotely controlling the game-specific pieces/objects on the main board. 
     Multiple Game Boards Used as Personal Game Terminals 
     In this configuration, there are a plurality of single-unit or multi-unit game boards. The game boards exchange information with one another. Personal game terminal functionalities may be available in each of the game boards, when each player holds his/her own board, and there is no separate main display module. In this configuration, the “public” playing area is displayed in all the single-unit or multi-unit game boards acting as personal game terminals, and the “private” playing area, if any, is superimposed or co-located with the public playing area. 
     Examples for games suitable for this configuration are Battleships. In the Battleship game, the public playing area is the main grid of the game, which is seen by all the participating players in their “Terminals”. But, on top of that, individual players see their “private” game-related information hidden from the other players. Stratego is another example game suitable for this configuration. 
     Example Gaming System 
       FIG. 1A  shows one example of a gaming system  100 , according to an embodiment of the present invention. In this embodiment, the system comprises a main board  102  and several personal game terminals, here four are shown,  104   a - 104   d . Each of the main board  102  and terminals  104   a - 104   d  runs a piece of software, indicated as QS, that enables execution and orchestration of various games, as selected by the users. In some circumstances, a general device, such as a PDA, smartphone, etc., can be used as a personal game terminal. In such a case, as shown in the callout of terminal  104   b , an augmentation layer AS runs on the native OS, and a game application GA runs on the augmentation layer. The augmentation layer and game application can be conceptualized as the QS software. 
     In one example for implementing the system of  FIG. 1A , the main game display module is a dedicated digital game board  102 . Board  102  is used for displaying the game layout, such as, the grid in a Scrabble game, and for enabling ‘public’ game related activities, such as, moving publicly visible Scrabble tiles and composing words on the game grid. Board  102  may be a TFT-LCD (Thin film transistor-liquid crystal display) or LED panel digitally emulating a printed game board. Game objects or game-specific pieces (dices, tokens, cards etc.) are emulated by digital graphic images. The game board  102  may be placed horizontally allowing several players to sit around it and play just like they would have done when playing with the paper-printed version of the board game. The board  102  may comprise more than one display units. Each display unit is capable of being coupled to another unit even if no other unit is physically connected to it at a given time instance. When the multiple display units are physically or logically aligned and coupled together, the system automatically identifies the new expanded available display structure and applies the game layout over the combined display units, forming a larger unified playing surface, duplicating the main image, partly-duplicating the main image, etc. 
     The game terminals  104   a - d  are used by each player for ‘private’ game activities, such as, privately viewing his/her current set of tiles in a Scrabble game or Cards in Texas Holdem. Though four terminals are shown in  FIG. 1A , the scope of the invention is not limited by the number of game terminals. Also, any type of smart personal device with a display, such as, a smart phone, a PDA, a personal media player, etc., may be used as the game terminal  104 , as long as the device is running the QS software so as to be configured to communicate with the game board  102 . 
     Players may interact with the system modules by using finger gestures (or a stylus) on the touch-screen on one or both of the game board  102  and the terminals  104 . Alternatively, a keypad, a set of buttons, a joystick, a trackball etc., may be used to receive player input. The movement of game specific pieces, known collectively as game objects, between the game board  102  and the game terminals  104  should be seamless. For example, a Scrabble tile&#39;s digital image may be ‘dragged’ from a game terminal  104  and placed on the main Scrabble grid on the game board  102  using, e.g., a hand gesture on the touch screen of terminal  104 . 
     According to one embodiment, movement of physical object can also be incorporated into the game. For example, a dice  103  is equipped with a transmitted device, such as Bluetooth or other transmission protocols or methods. Once the dice lands, it transmits the value shown by the dice. The main board  102  includes a receiver that receives the transmission from the dice and uses the information to advance the game. A similar implementation may be made with, e.g., sand clock  107 , game pieces, etc. 
     In an alternative embodiment, a role of a dice is implemented using transmission from the personal terminal  104  to the main board  102 . In such an implementation, an accelerometer may be embedded within the personal terminal  104 , so that when the user shakes the terminal it simulates shaking of the dice. Then, when a user makes a motion as if to “spill” the dice onto the main board game  102  (this can be sensed using, e.g., an inclinometer embedded in the terminal), the personal terminal  104  transmits to the main board  102  a transfer command that may include an identification of the dice, its speed of role, the strength of the user&#39;s motion, etc, whereby the personal terminal  104  shows a graphic of the dice falling off, while the main board  102  uses the data transmitted from the terminal  104  to show graphics of the dice rolling onto the main board  102  at the appropriate force and direction. The dice may also roll from one board to another, when more than one board are used for the main display. 
     In one example, when the main board is implemented as a television or remote monitor, the personal units operate in two modes: game mode and control mode. In game mode, the personal unit displays the personal screen of the game, and command entries of the user affect his/her personal terminal. For example, in card game the unit will display the personal cards of the player and the player may reorient the order of the cards shown on his/her personal display, add/remove cards from his/her personal display, etc. In control mode the unit is used to control the objects displayed on the main screen, e.g. to shuffle the card stack on the main board and distribute cards to the various players. 
     Each one of the game modules, i.e., main board  102  and personal terminals  104 , communicates with the other modules using either wireless or wired communication or shared memory interface to exchange game related information, timing information, and control information. 
     The gaming system  100  may have a games repository (shown in  FIG. 2 ), so that the same hardware can be used to play a variety of games. Games repository may be coupled to a web-based game repository  110  accessible via the Internet  108 , allowing players to download games into the system. Games repository may also reside on local permanent storage media (e.g., a hard drive), or removable storage media (e.g., a CD, an SD memory card, a USB flash memory device etc.) configured to load games into the gaming system  100 . The removable storage media insertion slot (shown as input slot  212  in  FIG. 2 ) may be built into the board  102 , or may be on an external work station  106  coupled to the board  102 . Work station  106  may also serve as the gateway to the Internet connectivity for game download, if the board  102  itself is not Internet-enabled. Work station  106  may also serve as the platform for developing and testing new games, or adding/modifying several features of existing games, managing individual player profiles, etc. All the activities that require for the ongoing usage of the system including players management, users&#39; favorites, handling terminals positioning and the merchandise of games content are available directly from the game board user interface. 
     The above configuration tasks are hidden during the game play and available through floating dashboard that can be launched anytime from pre defined key (e.g. &lt;Esc&gt;) or hot spot on the board (e.g. bottom left corner). 
     For a further illustration,  FIG. 1B  depicts an example of a set-up wherein a first main board  102   a  is a dedicated hardware placed on a table, and a TV set  102   b  is used as the second main board. Two personal units are used in this example, unit  104   a  being a dedicated hardware—here attached to the main board  102   a  so as to receive power for charging its batteries—and unit  104   b  being a standard PDA, smartphone, etc., running the QS software and communicating with main board  102   a  wirelessly. Alternatively, the TV set may be connected to intelligent processing unit  116 , which may be a pc, a media center, a game console, a set-top box, or embedded in the TV appliance. In such a case, the main board  102   a  function is replaced by the processing unit  116  running the QS software. The personal units  104  may communicate with the board processing unit  116  wirelessly. 
     System Initiation 
     When the game is initiated, for example, from main board  102   a , the processor of main board  102   a  publishes/broadcasts its existence and activates its receiver to recognize any other main boards or personal units in its neighborhood. For example, in the embodiment of  FIG. 1B , the main board recognizes the presence of the second main screen  102   b  and may prompt the users to select whether they wish to extend the main board display to unit  102   b . If so, the processor may prompt the users or use internal rules to determine how to extend the main screen into unit  102   b . That is, depending on the game selected by the users, unit  102   b  can be used to duplicate the screenshot of unit  102   a , to extend part of the screenshot to unit  102   b , to “smartly-duplicate” to unit  102   b , etc. Conversely, the main board may receive requests form other main boards to serve as a secondary board. Upon receiving such a request the main board may prompt the user for approval. The main board also loads the game from local or remote sources. 
     When the main processor detects that wired unit  104   a  is connected to the main board  102   a , it may prompt the user whether to accept the unit  104   a  as a player. If so, the main processor may display a gate or other graphical indication  112   a  associated with unit  104   a . If the location of graphics  112   a  does not correspond to the physical layout of the players with respect to main board  102   a , the users may “drag” the gate to a different location on the main boards  102   a  and  102   b .  FIGS. 1C-1E  illustrate the player positioning feature according to embodiments of the invention. The “Board subsystem” manages the players&#39; position on the board. The process may start with the collection of players with terminals or the definition of current players on the board (e.g. in case of Chess the terminal is not mandatory). Players positioning view shows a “symbol” for each player and let the users drag their symbols to their preferred side on the board. The process supports any number of players that can share the same side. For example, in  FIG. 1C  five players participate in the game, and each is depicted using a defined player&#39;s name and an image, which may be, e.g., a player&#39;s picture, an avatar, etc. In  FIG. 1D , each player is assigned a different color, so that they can be differentiated.  FIG. 1E  shows each player using a colored or shaded image. The above process may also define the area in which the player objects will be exchanged with the board, e.g. when he/she drop tiles from his terminal to the board, or drags cards from the board to his terminal. 
     In many games, the “Board subsystem” manages the turn of the players. When the turn is well defined, multiple players can share the entire side for drag-and-drop actions (vs. the case of using fraction of the side depends on the number of players). 
     The above process may be performed before any game starts and can be altered during the game. The defined positions and drag-and-drop areas may be viewed during the game as names, colors, avatars, and/or players pictures as additional “players&#39; layer” on top of the board area, as exemplified in  FIGS. 1C-1E . 
     In some games, when it&#39;s important that all players will know each other assets/status (e.g. chips in Poker, cash in Monopoly, or score in many games), the “players&#39; layer” may show in addition to their names, colors etc., their assets/status. 
     Alternatively, the above players&#39; details can be defined as “players&#39; box” that can be dragged to any area in the board and thereafter used as the players&#39; “gate” to the board (e.g. in Poker it makes more sense to position the “players&#39; box” adjacent to the table vs. the frame of the display, as illustrated in  FIG. 1E ). If the personal units are wireless, e.g., unit  104   b  is wireless, they attempt to detect the main board and request to join its space, if approved, the same positioning process apply. 
     If the personal units are hosted on smart devices, it&#39;s the QS software role to follow the same protocol, e.g. discover the board, request to join, and participate in the positioning process. It should be noted that this “discovery and acceptance” process is especially important in locations where many main boards are operating, such as in video arcades, etc. In such situations, many smart devices may try to communicate with many available main boards. In order to ensure that communication from each personal unit is directed to the proper main board, the unit must be “discovered and approved” by the main board. Once approval is granted, the personal unit can participate in a game on that accepting board, and communications from that personal unit will not affect any other main boards in the neighborhood. Additionally, during the discovery process, various actions germane to the game being played may be executed. For example, if the main board determines that the particular personal unit has already participated in this game in the past, it may interrogate the unit or its own memory for assets remaining (e.g., weapons, lives, etc.) from the previous game and make a note of the list of assets and may send an update to the terminal unit. Conversely, if the unit has not previously participated, the main board may issue initial set of assets to the unit. 
     Once communication is established and a personal unit is accepted to the game, the user can utilize the personal unit to control his/her actions in the game, as described more fully below. Additionally, when the game board is displayed on the TV monitor  102   b , and a user wishes to take an action on that board, e.g., move a game piece, it may be inconvenient to require the user to get up and walk to the TV, or using the TV remote control to perform the action. If the main board displayed on  102   b  is a duplicate of what is displayed on  102   a , then the user may simply drag the game piece on board  102   a . However, if it is not duplicate, then according to a feature of the invention, the user may switch his/her personal unit to operate in a control mode, wherein action on the personal units affect the TV monitor  102   b . This feature is illustrated in  FIG. 1F . To help the user, the display of the TV monitor  102   b  may be replicated on his personal terminal unit  104   b . Additionally, the user may be able to “zoom in” on selected areas of the TV monitor that is displayed on his/her personal unit (shown in the left-hand zoom-in drawing), so as to make it easier to select a game piece. In this mode the personal unit may also function as a wireless mouse or other such wireless input device. When the user returns the personal unit to terminal mode, action on his/her personal unit affects the game in the normal manner as described herein. 
     When a personal unit has been accepted to the game and has communication channel established with the main board, it may request from the main board a list of all other connected personal units and their relevant data. It may also be used be to communicate directly with other connected or unconnected personal units, for example to exchange game pieces, to share views, etc. If a communication is established with a personal unit that is not connected to the game/main board, the personal unit may send an invitation to the non-connected unit to join the game. 
     According to aspects of the invention, game pieces are moved seamlessly between each personal unit and the main boards, and optionally between two or more personal units. When such an action takes place, transfer rules are implemented. The rules may include instructions regarding the display of the transferred piece, instructions regarding actions to be taken upon transfer of the piece, etc. For example, when moving a card from unit  104   b  to main board  102   b , the rules may include displaying animation on unit  102   b , showing the card entering from gate  112   b  and moving to stack  114 , as illustrate by the broken-line arrow in  FIG. 1B . The action to be performed may include sounding an audio clip, playing a video clip, issuing another card from the stack, calculating score, etc. 
     According to another feature of the invention, main board  102   a  also serves as a charging hub. That is, when personal units  104  operate on rechargeable batteries, charging several units would requires the same number of wall outlets or a multi-outlet cable. Instead, according to a feature of the invention, main unit  102   a  includes a charging controller coupled to several outlets, so that each personal unit  104  may be connected to the main unit  102   a  for charging. 
     Working Modes for the Gaming System 
     The gaming system may support different working modes, controlled by the game&#39;s underlying software, as will be described below. Some example working modes are discussed here. 
     Single Board Mode 
     In this mode only one main game display unit comprises the game board  102 , and is used to display game layout and to receive player input. 
     Master-Dumb Mode 
     In this mode more than one display units comprise a game board  102 . Each display unit displays a portion of the game layout and provides input means with respective touch panels. A main display unit is fully equipped with a full set of controls. The other display units may also be fully equipped with controls, or include only respective display screen and touch screen modules. The other display units are physically connected to the main display unit and serve only as display extension, where the main display unit supplies both power and display distribution data. 
     Master-Slave Mode 
     In this mode more than one display units comprise a game board  102  and all the display units are fully equipped with controls. One of the display units is assigned to serve as the “master” and the other display units are assigned as slaves. The roles for each display unit are automatically negotiated between the units themselves and are confirmed by each unit. The participating units are coupled to each other in two-dimension forming a large display structure and communicate with each other in order to exchange control and application related information. 
     Distributed Software Engine 
     The gaming system according to embodiments of the present invention is powered by a software engine distributed across the system hardware components, such as, the components shown in  FIG. 2 . The distributed software engine comprises several software packages, each of which handles different levels of the system, including the game board(s) and terminals, the game development environment and the web services. 
       FIG. 1G  shows a high-level schematic representation of the distributed software engine, where the software engine components are distributed between the game board  102 , terminal  104 , web-based game repository  110 , and work station  106 . Persons skilled in the art will appreciate that the distributed software engine automatically controls many of the features of the gaming system, while letting some other features (related to a specific game or a specific player profile) to be customized by the players so that they can enjoy a rich user-experience while playing (e.g. personalizing the pictures in the Memory game). 
     Customization can be done at the web-based game repository  110 , at the work station  106  (by the game developers), or locally at the game board  102 , as shown in  FIG. 1G . Players have the option to use predetermined game properties loaded as default options at the board  102 , at the game terminal  104 , at the work station  106 , and at the web-based game repository  110 , or customize the properties according to their preference. Some of the game properties may not be changed, for example, some fixed game rules are recommended to be left intact. Work station  106  may be used by game developers for creating new games or new features of an existing game using a game development software toolkit. Proprietary or standard communication protocols (indicated by the “comm.” functional blocks in the work station  106 , game board  102 , and game terminal  104 ) are used between gaming system components to exchange game-related information. Game board  102  may have intra-module communication protocol to identify and communicate with multiple display units in one main game board or multiple main game boards, and inter-module communication protocol for identifying and communicating with game terminals  104 . 
     A game board  102  may offer a generic player profile to the players, which can be customized by the players using profile manager software module, and the customized profile is saved in persistent database DB. 
     The web-based game repository  110  may provide various customer service options, such as, game download support (from server or from users using peer-to-peer services), subscription and billing management, new feature suggestion, user feedback collection, etc. 
     System and Application Software Packages 
     The two main software packages included in the distributed software engine are: the “System” package, which handles the platform dependent functionality, and the “Application” package, that handles the game related activities. The System package is responsible for managing and controlling different hardware elements (e.g., game-boards  102  and game-terminals  104 ) and their communication, and is responsible to provide all the services required by the Application package to execute and control any desired game independently of the actual hardware setup. 
     System Software Package 
     The system package of the distributed software engine may interpose an intermediate augmentation layer to work with an existing native operating system on various system components, so as to create an application-specific environment. Alternatively, the distributed software engine may also include a full-fledged stand-alone application-specific operating system, rather than interposing an intermediate augmentation layer coupling an application layer with a native operating system. When the system package is in the form of an augmentation layer, it provides two essential services: i. translating controls between the application software and the native OS, and ii. providing game-related services not provided by the native OS. Providing the translation services by the augmentation layer provides game developers with the freedom to develop games without regards to the OS the game will be played upon. It also enables playing a game with several units, each running a different native OS. The function of providing game-related services makes it easier for game developers to develop games by simply inserting calls to the augmentation layer when needing a service. For example, the augmentation layer may provide services such as, rolling a dice, shuffling a deck of cards (e.g., using random number generator), generating hectic sensation (e.g., by activating vibration in the handheld unit), etc. 
     The system package associated with the board  102  is referred to as a game board system package. The game board system package is responsible for identifying the working mode of the game, examples of which are discussed above. Upon game initialization, the main display unit of the game board  102  looks for the presence of other display units. As long as no additional display unit is detected, the board  102 &#39;s working mode remains “Single-Board mode”. In this mode, the board  102 &#39;s CPU (central processing unit) sends all the display information to its screen. In case another display unit was physically detected, the main display unit validates the other unit characteristics over the physical connection and moves to “Master-Dumb mode” or “Master-Slave mode” accordingly. In case of “Master-Slave” mode, all the display units negotiate in order to determine which board is taking the Master role. 
     In addition to communicating between the video controllers of the various display units to display the game surface properly, player input is also managed by the board system package according to the working mode. In Single Board working mode, the only source for player input is the board&#39;s touch panel or key pad (or trackball, joystick, buttons, etc.) going to the board&#39;s CPU. In Master-Dumb mode, both the master and dumb touch panels or key pads (or alternative tracking mechanisms) are connected to the main board CPU which identifies the input source and translates its position in reference with the entire displayed area. In Master-Slave mode, each board&#39;s CPU receives the player input from its own touch panel. Once received, each CPU immediately sends the input information to the other boards through the communication channel. In this mode, each CPU works independently and acts as if it is the one entity that manages the whole application (i.e. the application/game is simultaneously being executed on each one of the connected boards) but displays only the portion assigned previously by the master board. 
     Game board system package also handles low-level communication between the main game-board and the game-terminals by implementing a data transfer protocol to be used by the application package. The Game board system package also may establish communication with web-based game repository, for example Q-store by Quado Media. 
     The system package associated with the game terminal  104  is referred to as a game terminal system package. The game terminal system package is responsible for the display management in the terminals  104 , player input management in the terminal  104 , and the low-level communication between the terminals  104  and the game board  102  by implementing a data transfer protocol to be used by the application package. 
     Application Software Package 
     The Application software package is responsible of handling the interaction with the players and any related game functionalities. The package includes a 2D and/or 3D graphic engine and the implementation of different board games for the game platform. 
     The game board application package initializes the application software modules, and displays the main menu (home page) allowing a player to select any available game or sub-menu. Once a game is selected, the game board application package loads and displays the game layout and all the relevant game objects. The player may, by means of fingers gestures over the touch-screen, or pressing keys, or moving a joystick, move any game objects and position them in any desired location. Some game objects, upon movement and interaction with other game objects, may be configured to launch a set of pre-defined animation video clips and sounds. A game object may be moved by the player from the game-board  102  screen to be displayed on a game-terminal  104  screen and from the game-terminal  104  screen to the game-board  102  screen. 
     The application package uses the communication services that are provided by the system package to exchange game objects between the terminals  104  and the boards  102  as well as for sending game-related control messages. 
     Other functionalities controlled by the application software may include displaying the game instructions upon player request (e.g., when the player accesses the Help menu), saving game status for restoring session in future, indicating playing turns in a multi-player game, adding/removing players, changing game levels, adjusting audio and/or display, changing game skin, etc. In case a removable storage media is inserted, the application software may automatically launch the game stored on the storage media, or a game menu to choose from. 
     The game terminal application package initializes all the application software modules, and manages seamless visual transition of game objects between the game terminals and the main game board screen. In addition, the terminal application package displays game related controls and information, such as, the player&#39;s points or status. The application uses the communication protocols that are provided by the system package to exchange signals for transitioning game objects between the game terminals and the game boards as well as for sending game-related control messages. 
     Components of Distributed Software Engine 
       FIG. 2  shows a high-level representation of some of the components of an example distributed software engine with respect to the hardware components of the gaming system and associated functionalities in one embodiment. The broad purpose of the distributed software engine is to enable one or more players to play games interactively. Players interact with the game board  102  (which may also be an existing appliance with a display, such as a TV, a computer, a tablet PC, etc., running corresponding parts of the distributed software engine.). Each player may have a corresponding personal game terminal  104  (which may also be a cell phone, a PDA, a remote control device, a game console etc., running corresponding parts of the distributed software engine as discussed before). One of the tasks of the distributed software engine is to manage the players&#39; profile for a specific game or a host of games supported by the gaming system. Another task is to enable seamless transfer of digital game pieces between and among the terminals and the board or boards. 
     In  FIG. 2 , the thick arrows indicate many to one communication, and the thin arrows indicate one to one communication. 
     The game board  102  displays the shared public region of the game surface  232 . Game board  102  may have an input slot  212 , through which a specific game is loaded from a game repository  210 . Game repository  210  may be configured to download games from a web-based game store  110 , as discussed with respect to  FIG. 1A , or it could be local. 
     Game board  102  may or may not have a native operating system  220  (such as, Linux or Windows XP etc.). If a native operating system  220  exists in the board  102 , then the distributed software engine&#39;s augmentation layer comes into play to associate application-specific software components with the board&#39;s native operating system  220 . A portion of the distributed software engine associated with the board  102  controls the functions of a graphic engine  228 . Graphic engine  228  is configured to control the display of a game surface  232 , either spread across several display units constituting the board  102 , or displayed on just a single display unit constituting the board  102 . Graphic engine  228  may or may not dynamically change orientation of the game surface  232  based on player&#39;s viewing preference (which may be linked with the player&#39;s sitting position). Graphic engine  228  may also launch a game&#39;s fundamental layout, and starting position, e.g., laying out the grid in a Scrabble game, and organizing the cards in the players hand in card games. 
     Board server  222  is the “brain” of the distributed software engine for the board  102 . Note that the word “server” encompasses both the hardware and the software associated with performing a specific function of the gaming system. However, in the context of the description of the distributed software engine, the term “server” is used primarily to mean the software component. Board server  222  is implemented on top of an existing native operating system  220 , or board server  222  may include an application-specific operating system. The board server  222  detects and registers itself on the local network, communicates with other distributed software engine components, schedule games and manage licensing and caching functions of various games. 
     Board server  222  may implement other servers  226  for specific purposes. For example, a communication server may handle the communication and negotiation between various software engine servers (such as the board server  222  and a terminal server  244 ), a cache server may handle the caching of games content, a licensing server may enforce the games licensing policy, and so on. 
     Game server  224  is the active game “brain” that is spawned by the board server  222  when the players select a new game to start. Game server  224  records and updates the game status (e.g., maintains a list of current players, each player&#39;s scores etc.), manages the game flow, communicates with the game repository  210  for additional game-related information, and communicates with other servers (e.g. cache management communication with a cache server). 
     Game package  236  includes the code, graphical objects, logic, and essential licensing information that the distributed software engine understands and executes. Game packages  236  are available at the game repository  110  on the web, or on removable storage device that can be inserted or plugged in to the board  102 . Game package may also be loaded in the local hard drive of the game board  102 . Game package  236  is the part of the distributed software associated with the hardware described as the game repository  210 . 
     Game surface  232  is the graphic layout of the game. The game surface  232  can be defined on a single board  102  (with one or more display units), or on multiple boards  102  (each board  102  having one or more display units). The equivalent of game surface  232  that is extended to terminals  104  is called a terminal view  246 . Game widgets  240  and game objects  238  associated with the game are moved between different portions of the game surface  232  (and the terminal view  246 ) displayed on different modules. A component of game surface  232  is a surface area calculation engine  230 , which computes which portion of the game surface  232  is going to be rendered on which display unit, in the case of a multi-unit game board  102 . 
     A portion of the distributed software engine, called a terminal server  244 , resides on each terminal  104 , and helps associate individual players to corresponding terminals  104 . It may be possible to accept/reject players or terminals on the fly during an active game, and to associate players&#39; or terminals&#39; positions around the board  102 . Terminal server  244  is the “brain” on the corresponding terminal  104 . Terminal server  244  is typically implemented on top of the terminal&#39;s native operating system  242 . For example, a dedicated game terminal may have a Linux-based application-specific native operating system. On the other hand, a smart phone used as a terminal  104 , such as an iPhone, may have a native operating system (e.g., OSX) installed in it. Terminal server  244  acts as an application server that communicates with the native operating system  242  via an intermediate augmentation layer. Terminal server  244  communicates with the board server  222  and the game server  224  and manages player interaction. 
     A graphic engine  248  for the terminal  104  interacts with terminal native operating system  242  (possibly via the augmentation layer), and controls terminal view  246 , i.e. the portion of the game surface  232  that is displayed on the terminal  104 . Terminal view  246  usually includes a few game widgets  240 , game objects  238 , and other utilities that are used by individual players during the game play. 
     Game widgets  240  are special digital widget that are necessary for particular games. Examples of game widgets  240  are Scrabble bag, dictionary, dice tray, etc. Game widgets  240  have special function in the game flow and usually special location on the game surface  232  and/or terminal view  246 . 
     Game objects  238  comprise movable objects of the game, such as, tiles, cards, tokens, etc. Game objects  238  have a starting location on the game surface  232  or terminal view  246 , and associated moving rules, visual rules, impact rules, etc. Players typically move game objects  238  on the game surface  232  and to/from the terminal view  246 . The movement of game object  246  is seamless. For example, as soon as a game object  238  is ‘dragged’ out of a terminal view  246 , it appears on the game surface  232  on the game board  102 , so that a player can continue to use the same game object  238  on the game surface  232 . 
     Physical Components of an Example Gaming System 
     The gaming system according to one embodiment of the present invention comprises a main digital game board  102  and one or more game terminals  104 . The game board  102  acts as the shared public playing surface of the board game. As shown in  FIG. 3 , game board  102  comprises a display screen  302  (e.g., TFT-LCD panel, Organic light emitting diode (OLED) display or electronic paper or any other type of flat-panel display) for displaying a game board layout, and different game objects and graphic elements. A touch panel  304  may cover all or most of the display screen  302 &#39;s surface, providing input means to the players. Other components of the game board include a speaker  306 , a keypad  312 , a video controller unit  308 , a touch panel controller  310 , a central processing unit  314  (which may include a graphic processing unit GPU), random access memory (RAM)  316 , flash memory  317 , a removable media/memory insertion slot  318  (e.g., a SD card socket), removable memory  320 , a battery pack  322 , a power jack  324 , a power switch  326 , a wireless communication unit  332 , a wired communication unit  330 , one or more magnetic and/or mechanical connectors/sockets  328  (to couple one board unit with other similar units, and to connect game terminals  104 ), etc. Other optional/additional components not specifically shown in  FIG. 3  may include a microphone (for voice recognition interface), a vibrator for associating haptic feedback with the touch panel  304 , etc. Persons skilled in the art will recognize that not all of the above components are necessary in all embodiments, and there may be additional components in certain embodiments, but the scope of the invention is not limited by the cited example components. 
     The game board battery pack  322  may comprise non-rechargeable use-and-throw batteries or may be configured to be charged from an external power supply unit, which is connected to the electricity outlet via power jack  324 . 
     The game application runs on the CPU  314  via the OS and augmentation layer, so as to make the CPU  314  execute various operations in conjunction with the other elements of the board. The communication may be made over a bus  341 , such that the CPU can send or receive communication from connection sockets, wireless and wired units  328 ,  330  and  332 , receive input from the keypad  312 , and send sounds to the speaker  306 , etc.  FIG. 3A  illustrates an example of a process executed by the CPU  314  for initiating a game session. The process initiates at Step  300  and at Step  302  the CPU publishes its existence by, for example, broadcasting a signal over the wireless unit  332 . At Step  304  the board checks whether the wireless unit  332  received any communication from another board and, if so, it continues to sub-routine at Step  310  by registering the properties of the second board in its memory, e.g., RAM  316 . At Step  312  the board displays the properties of the second board on the display  302  and query the user whether to add the second board to the session. If at Step  314  the user indicates to include the second board in the session, the CPU updates a registry at Step  316  to indicate that game applications can be displayed using both boards. At Step  318  the CPU checks to see whether another board is available to join and, if so, reverts to Step  310 . Otherwise, it continues to Step  306 , where it checks whether any terminals have transmitted a request to join the session. If so, it executes a subroutine starting at Step  320  where the CPU registers the terminal&#39;s properties in its memory, e.g., RAM  316 . At Step  322  the board displays the properties of the terminal on the display  302  and query the user whether to add the terminal to the session. If at Step  324  the user indicates to include the terminal in the session, the CPU updates a registry at Step  326  to indicate that the terminal may participate in the session. At Step  328  the CPU displays an icon (e.g., digital game piece, avatar, etc.) corresponding to the terminal and shows its position on the board (as noted elsewhere, the position may be changed by the user, and this can be handled using an interrupt subroutine). At step  329  the CPU checks to see whether another terminal is available to join and, if so, reverts to Step  320 . Otherwise, it continues to Step  330  and displays the game applications available. Once a user selects a game form the displayed application, the CPU uploads and executes the game application at Step  332 . 
     A single display unit  402  of game board  102 , as seen externally, is shown in  FIG. 4 , showing a display screen  302  and a touch panel  304  encased in a housing  450 . Housing  450  may be metallic or made of plastic or other materials. In this example embodiment, one or more sockets  430  located on the side(s) of the rectangular housing are used to connect the game board  102  to corresponding game terminals  104  (not shown) using specific cables. The connecting cables may feed power to the terminals  104  from the board  102 &#39;s power supply, if the terminals don&#39;t have their own power source or for charging the terminal&#39;s batteries. The connecting cables may also serve as communication link for transferring game-related information between the game board  102  and the terminals  104 . The cables may be connected to the board and the terminal using quick-release magnetic connectors or other type of fastening mechanisms. Alternatively, game terminals  104  (or other devices used as game terminals) may be wirelessly coupled to the game board  102 , as shown in  FIG. 9 . 
     Additional game-board display units can be optionally attached to the display unit  402 . The units  402  may be identical to each other, or may be an extension game board display unit which is driven by a main game board display unit, which serves as the ‘master’. An extension game board display unit may only have a subset of hardware components, such as an LCD display screen, a touch panel, and a video controller. For attaching one game board display unit  402  with another, one or more magnetic connectors  428   a - b  are provided on at least one side of the housing  450 . Other types of connectors may be used too. Magnetic connectors  428   a - b  are designed for firm attachment with another similar unit  402 . A power connector may be embedded within the magnetic connectors  428   a - b  or is otherwise formed (e.g., embedded within a multi-purpose connector  429 ) to enable power-sharing between display units  402 , or to enable feeding power from a master unit to an extension game board display unit. 
     The multi-purpose connector  429  is located for establishing communication (and/or power) link between two or more display units  402 . Inter-unit communication includes sharing touch panel input, multi-screen display sharing information, seamless game object movement, routing of terminal communication received by an extension game board display unit to the master unit&#39;s CPU, clock synchronization signal etc. 
       FIG. 5  shows an embodiment, where transfer of electronic signal between two game board display units  502  are carried out through a pin array  530  (magnified view shown in insert) embedded within the magnetic connectors  528   a - b . Display unit  502  is very similar to display unit  402  with a few exceptions. The magnetic connectors  528   a - b  facilitate in establishing reliable contact between pin arrays  530  of two game board display units by securing proper alignment and firm attachment. In the embodiment shown in  FIG. 5 , multi-purpose connector  429  may be redundant. Also, display units  502  may have externally hidden wireless communication ports for communicating with game terminals. 
       FIG. 6A  shows how two display units  502   a - b  are aligned side by side before attachment, and  FIG. 6B  shows how a unified dual-screen game board  602  is formed after the units  502   a - b  are combined. 
       FIG. 7A  shows that players have the option to keep two display units  502   a  and  502   b  separate, each displaying the same game layout, symbolically indicated by the smiley faces. Another option is to spread the game layout between two screens, as shown in  FIG. 7B . As the display units  502   a  and  502   b  are attached to each other, the system automatically spread the game layout among multiple screens. 
       FIG. 7C  illustrates an embodiment of the game wherein the main board  102  includes facility to contain the terminals  104   a - 104   d . In  FIG. 7C  terminals  104   a  and  104   b  are illustrated fully deployed and positioned for playing. On the other hand, terminal  7   c  is illustrated partially deployed from the “docking” position in the main board, while terminal  104   d  is illustrated fully docked to the main board  102 . 
     The game terminal  104 , shown in  FIG. 8 , may be a hand-held device, which acts as a player&#39;s personal playing zone with private personal information and/or public personal information in it. Game terminal  104  may comprise a display screen  802  (e.g., TFT-LCD panel, OLED display or electronic paper or any other type of flat-panel display) for displaying a terminal view layout, and different game objects and graphic elements. A touch panel  804  may cover all or most of the display screen  802 &#39;s surface, providing input means to the players. Other components of the game terminal  104  include a keypad  812 , a video controller unit  808 , a touch panel controller  810 , a central processing unit  814  (which may include a graphic processing unit GPU), random access memory (RAM)  816 , flash memory  817 , a battery pack  822 , a power jack  824 , a power switch  826 , a wireless communication unit  832 , a wired communication unit  830 , one or more connectors/sockets  828  (to couple via cable to the game board  102 ), etc. Other optional/additional components not specifically shown in  FIG. 8  may include a microphone (for voice recognition interface), a speaker, a vibrator for associating haptic feedback with the touch panel  804 , an accelerometer to enable player input by movement detection, etc. Persons skilled in the art will recognize that not all of the above components are necessary in all embodiments, and there may be additional components in certain embodiments, but the scope of the invention is not limited by the cited example components. Terminal battery pack  822  may receive power from main board  102  through appropriate connectors/cables. 
     The game application runs on the CPU  814  via the OS and augmentation layer, so as to make the CPU  814  execute various operations in conjunction with the other elements of the terminal. The communication may be made over a bus  841 , such that the CPU  814  can send or receive communication from connector  828 , wireless and wired units  830  and  832 , receive input from the keypad  812 , and send sounds to the speaker  806 , etc.  FIG. 8A  illustrates an example of a process executed by the CPU  814  for initiating a game session. The process initiates at Step  800  and at Step  802  the CPU searches for available boards by, for example, listening for a broadcasting signal received over the wireless unit  832 . At Step  804  the terminal checks whether the wireless unit  832  received any communication from a board and, if so, it continues to sub-routine at Step  810  by registering the properties of the board in its memory, e.g., RAM  816 . At Step  812  the terminal sends a request to the board to join the session. If at Step  814  the terminal receives a signal from the board that indicates that the terminal may join the session, the CPU  814  updates a registry at Step  816  to indicate that terminal has been accepted to participate in a session with that specific board. At Step  806 , the terminal checks whether any other terminals are available to join the session. This information would generally be provided from the main board/console. If so, it executes a subroutine starting at Step  820  where the CPU registers the terminal&#39;s properties in its memory, e.g., RAM  816 . At Step  822  the terminal sends a signal to the other terminal requesting to establish communication. This can be done by communicating via the main board. If at Step  824  the other terminal indicates that it accepts the invitation, the CPU updates a registry at Step  826  to indicate that the terminal may participate in the session. At Step  828  the CPU checks to see whether yet another terminal is available to join and, if so, reverts to Step  820 . Otherwise, it continues to Step  830 , wherein, if a user selects a game form the displayed application, the CPU  814  receives a signal from the board indicating the initial properties (available currency, cards, lives, turn in the game, etc.) of the terminal according to the game application. 
     Smart Mobile Device as Game Terminal 
     As discussed before, instead of a dedicated game terminal provided by the gaming system, smart mobile devices, such as, smart phones, smart media players, PDAs, etc. may be used as game terminals.  FIG. 9  shows smart phones  904   a - b  interacting with a game board  602 . 
     In case a smart mobile device is used as the terminal, an application software running on the mobile device will implement all the standard terminal protocols to communicate with the game board. 
     In addition, the application software running on the mobile device, upon registration, may report to the game board the device&#39;s physical properties (such as, screen size and resolution details) in order to allow the game board application software to tailor the relevant properties to the device&#39; attributes. 
     Packaging of the System 
     The game board display units may be hingedly pre-attached to each other, and placed in an external casing device such as a folding plastic case to allow a convenient method of storing and deploying several units. For example, in a two-screen device, when the external casing is folded, the two units are vertically stacked against each other with the display screens facing each other. 
     Another packaging method is to include magnetic and/or mechanical contactors around the periphery of the display screen of each detached game board display unit, so that when two display units are stacked on top of each other, the corresponding display screens face each other and are held together by the contactors. 
     The game terminals may be placed on one of the game board display unit&#39;s back plane, and may be held securely by magnetic and/or mechanical contactors. 
     The scope of the invention is not limited by the packaging and storing method. However, in various embodiments of the present invention, game boards  102  and game terminals  104  are designed to facilitate easy storing and easy deployment. 
     Examples of Player Interaction 
     This section discusses various examples interaction methods used by the players, which the system interprets as appropriate commands. Most of these interactive methods are associated with finger gestures on a touch screen, but persons skilled in the art would understand that these illustrative examples are not limiting the scope of the invention. 
     Drag—When using a movable game object like a scrabble tile or chess piece, the player touches the piece and while touching it, moves the finger along the display area. The selected object will follow the finger as long as it touches the screen surface. Depending on the game specifics, the object will may stay (graphically) on the game surface (e.g., in a chess game), may be “lifted up” when moving around to avoid collision with other objects (e.g., in the Checkers game). In case multiple display units are involved, the moving game object may be moved from one display unit to the other by continuous “dragging” across the boards. 
     Spin—When using a spinning object like a roulette wheel or carousel, the player touches the object and while touching it, moves the finger in the spin direction and then lifts the finger up. The object will start spinning to the selected direction using the finger movement speed to determine the spinning speed. 
     Throw—When using a game piece that requires the player to throw it across the board, like a dice, the player touches the object, which will graphically “elevate”. While touching the object, the player moves the finger in the throwing direction. The object will follow the finger moving velocity and direction, and the moment of release to determine the bouncing scheme. In case the object collides with other game objects, it will change its direction accordingly until it will come to a halt. If an accelerometer is incorporated into the handheld device, the user may simply shake the handheld device, e.g., to shake the dice, and then gesture as if to spill the dice out of the handheld device. 
     Object exchange between different modules—In order to move objects from the shared public zone to a personal public/private zone, and vice versa, one option is to graphically define a “gate” on the display area. Once the object is dragged into the players “gate”, it will disappear and reappear onto another display screen. To move from the terminal to the board, the player will drag the object towards a physical boundary of the display screen, and once most of the object body will cross the border, it will disappear from the terminal and reappear at the player&#39;s “gate” on the main board. The gate may be located near the terminal&#39;s cable socket or location. 
     Page Flip—In case an game object resembling a page, a page flipping emulation can be done by touching the page corner and moving it to the opposite direction 
     Collision—In case two objects are colliding, collision behavior may be emulated with visual, audio, or audio-visual effects. 
     Push—When a finger is moved gently touching a movable object, the object will be ‘pushed’ along with the finger movement. 
     Hit—Unlike the push gesture, in case the finger moves fast enough when touching a movable object, the impact will simulate a hit, where the object will bounce to the finger&#39;s movement direction. 
     Flip—In order to flip a card or tile, the finger will touch the object&#39;s center and while touching, will move fast toward one of the card edges and then will release the touch. The object will be flipped with animation effect. 
     Write—Using a stylus pen or finger on a predefined area, the player can write or draw, if required by the game. 
     Zoom out and in—Using finger pinching or expansion, a player may zoom out or in on certain portion of a game surface. 
     Rotate board—Special control on the board, on the user terminal, or gesture on the board layout enables to rotate the entire board and pieces to the user side. The same function may take place automatically when the user turn arrives as part of the game play. 
     Physical buttons or keypads, mouse, virtual keyboards, joysticks, trackballs, touch pads, etc. may be used instead of a touch screen to interact with graphical objects on a display screen.
