BACKGROUND OF THE INVENTION

1. Field of the Invention

This patent application pertains generally to gaming systems, and more particularly, but not by way of limitation, to a system and method for displaying three-dimensional gaming effects in a gaming machine.

2. Background Information

Video gaming machines are popular within the gaming industry. They typically are operable to play traditional games such as slots, poker, bingo, keno and blackjack. Such machines have been enhanced in recent years by adding effects that make them more attractive, exciting and entertaining.

Pick games are a popular type of game. In a pick game, the player chooses from a number of selections. The selection then triggers particular gaming outcomes. Pick games are either used alone, or in combination with reel-based games to provide bonus events. Bonus events occur outside the reel spin, injecting either a random event or fostering some player interaction to trigger a random event.

The graphical capabilities of processors have increased dramatically over the last decade. At the same time, there is a continuing need to develop new and exciting effects for video gaming machines. What is needed is a way of harnessing the graphics power of processors to introduce new and innovative pick games in video gaming machines.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1illustrates an exemplary video gaming machine10, also referred to as a Video Lottery Terminal (VLT), in which embodiments of the invention may be implemented. In some embodiments, gaming machine10is operable to conduct a wagering game such as mechanical or video slots, poker, keno, bingo, or blackjack. The gaming machine10shown inFIG. 1includes a video display12such as a cathode ray tube (CRT), liquid crystal display (LCD), plasma, or other type of video display known in the art. In one such embodiment, a touch screen overlies the display12. In the illustrated embodiment, the gaming machine10is an “upright” version in which the display12is oriented vertically relative to a player. Alternatively, the gaming machine may be a “slant-top” version in which the display12is slanted at about a thirty-degree angle toward the player. Other orientations could be used as well.

Gaming machine10includes one or more credit receiving mechanisms14for receiving credits to be used for placing wagers in the game. The credit receiving mechanisms14may, for example, include a coin acceptor, a bill acceptor, a ticket reader, and a card reader. The bill acceptor and the ticket reader may be combined into a single unit. The card reader may, for example, accept magnetic cards and smart (chip) cards coded with money or designating an account containing money. In some embodiments, credit receiving mechanism14receives credits through a network interface.

In some embodiments, the gaming machine10includes a user interface comprising a plurality of push-buttons16, the above-noted touch screen, and other possible devices. The plurality of push-buttons16may, for example, include one or more “bet” buttons for wagering, a “play” button for commencing play, a “collect” button for cashing out, a help” button for viewing a help screen, a “pay table” button for viewing the pay table(s), and a “call attendant” button for calling an attendant. Additional game specific buttons may be provided to facilitate play of the specific game executed on the machine. The touch screen may define touch keys for implementing many of the same functions as the push-buttons. Other possible user interface devices include a keyboard and a pointing device such as a mouse or trackball.

A processor controls operation of the gaming machine10. In response to receiving a wager and a command to initiate play, the processor randomly selects a game outcome from a plurality of possible outcomes and causes the display12to depict indicia representative of the selected game outcome. In the case of slots for example mechanical or simulated slot reels are rotated and stopped to place symbols on the reels in visual association with one or more pay lines. If the selected outcome is one of the winning outcomes defined by a pay table, the processor awards the player with a number of credits associated with the winning outcome.

FIG. 2is a block diagram of a control system suitable for operating the gaming machine10. Money/credit detector22signals a processor20when a player has inserted money, tickets, tokens, cards or other mechanism for obtaining credits for plays on the gaming machine through credit mechanisms14. Using a button panel16and/or a touch screen18, the player may select any variables associated with the wagering game and place his/her wager to purchase a play of the game. In a play of the game, the processor20generates at least one random event using a random number generator (RNG) and provides an award to the player for a winning outcome of the random event.

Alternatively, the random event may be generated by a remote computer using an RNG or pooling schema and then transmitted to the gaming machine. The processor20operates the display12to represent the random event(s) and outcome(s) in a visual form that can be understood by the player. In addition to the processor20, the control system may include one or more additional slave control units for operating the display12and any secondary displays.

System memory24stores control software, operational instructions and data associated with the gaming machine. In one embodiment, the system memory24comprises a separate read-only memory (ROM) and battery-backed random-access memory (RAM). However, it will be appreciated that the system memory24may be implemented on any of several alternative types of memory structures or may be implemented on a single memory structure.

A payoff mechanism26is operable in response to instructions from the processor20to award a payoff to the player. The payoff may, for example, be in the form of a number of credits. The number of credits is determined by one or more math tables stored in, for example, system memory24.

In one embodiment, gaming machine10includes a reel-based game with three-dimensional game effects.

In one embodiment, three-dimensional games are implemented using a game design package such as RenderWare Studio 2.0 running, for example, on a processor designed by Intel or AMD.

An interesting pick game can be made based on the simulation of physical objects. In the example shown inFIG. 3, an array of pick fields40is shown located above rows of pegs42and spinners44on a display12. A player selects a pick field40, releasing a drop of fluid from the vicinity of the pick field40. System10simulates the effects of gravity as the drop falls into the field of pegs42and spinners44, breaking into smaller drops as they encounter the pegs42and spinners44. The drops either fall into buckets46or appear to fall off display12.

In one such embodiment, each drop adds some volume to the fluid accumulating in the bucket46into which it falls. The player can track how full each bucket is by comparing the level of the bucket46to gradation levels48. At the end of game play, system10evaluates each bucket and pays out based on the level of fluid in each bucket46.

In one embodiment, as is shown inFIG. 4, processor20displays an image at50having two or more picks. Processor20receives the player's pick at52and simulates at54a drop of fluid falling through objects such as pegs42and spinners44to fall in or past buckets46. Processor20then determines a gaming outcome at56as a function of the simulation.

In one embodiment, the fluid simulated is a dense liquid such as mercury.

In one embodiment, players select from variables effecting game play. For instance, one player may select to play in a system with low gravity, or to play in a system with many, smaller drops of fluid, or with different or multiple fluid densities.

In one embodiment, players can activate two of more pick fields40, generating two or more drops that cascade through pegs42and spinners44fall on or past buckets46.

In one embodiment, drops come in more than one color. In one such embodiment, drops layer into buckets46such that the colors do not mix. In another embodiment, the colored drops mix, with the shade of color in each bucket46acting to multiply the bucket's value. In yet another embodiment, a particular “special” color globule (e.g., red or gold) falling into a bucket46turns the bucket that color, multiplying the bucket's value.

In one embodiment, a drop changes color when it contacts particular objects. For instance, a gold peg would change the color of a drop to gold. If that drop fell into a bucket, it would multiply the bucket's value.

In the above discussion, the term “processor” is defined to include any digital or analog data processing unit. Examples include any microprocessor or microcontroller capable of embodying the inventions described herein.

Examples of articles comprising machine readable media are floppy disks, hard drives, CD-ROM or DVD media or any other read-write or read-only memory device.
