Abstract:
A hand-held opaque playing board has a different maze structure on each of two faces with holes passing through the board between the two maze structures. Each maze structure is divided approximately in half by an impassable barrier. Gravity moves the playing piece when the board is tilted. When the ball passes through the board from one maze structure to the other, the board must be turned over to view the other maze structure. The ball must travel from the start position at one end on one face through the maze structures back and forth through the board until the playing pieces lands in the finish position at the other end on the other face in the shortest time. The maze can also be played on a hand-held electronic device or on a stationary screen device, such as a computer, using a controller to simulate tilting and turning the board.

         [0023]    U.S. Pat. No. 615,413, issued Dec. 6, 1898 to Sharpe, illustrates a puzzle board provided with a series of pins and suitably-arranged pockets or receptacles, said pins forming labyrinth paths in which a ball is made to travel by tilting or otherwise manipulation the board, and are thus caused to enter said receptacles or pockets. 
         [0024]    U.S. Pat. No. 3,785,651, issued Jan. 15, 1974 to Smith, is for a cube having a maze contained therein through which a ball is movable. The puzzle has a transparent outer enclosure containing the maze and ball. Nontransparent intermediate walls are positioned inwardly of each transparent wall providing a space on each side of the cube in which the ball is freely movable. The nontransparent intermediate walls are provided with the holes through which the ball is passable to the maze within the intermediate walls. One hole is bisected by an inner wall thereby allowing the ball to go in one of two opposite directions. The maze extends vertically and horizontally through the cube. 
         [0025]    U.S. Pat. No. 3,787,054, issued Jan. 22, 1974 to Stafford, shows a puzzle having a maze through which a contained ball traverses. A cubicle main body is provided with non-transparent outer walls with a plurality of inner walls mounted therein defining a single non-continuous tortuous passage having a start and finish without any dead end passages. A pair of transparent windows mounted to the outer walls of the main body are positioned at the start and finish of the passage. A ball is positioned within the main body and is movable from the start window through the passage to the finish window. The ball is not removable from the main body. In one embodiment, the inner walls are nontransparent thereby preventing visual determination through the windows of the tortuous passage. In another embodiment, some of the inner walls are transparent allowing a person to visually determine through the windows a portion of the tortuous passage. In another embodiment, all of the inner walls are transparent. 
         [0026]    What is needed is a two sided maze structure with a different maze on each face of an opaque playing board with a middle barrier in each maze on each face dividing each face into two adjacent visible mazes with no passageway from one to the other and with openings through the playing board between the two faces requiring a user to tilt the playing field to roll a ball through each of the mazes and drop the ball from a top face to a bottom face and back and forth repeatedly with only one face visible to a player at a time requiring the player to pass from a starting indentation at one end of a top maze and land the ball in a finish indent in an opposite end of the bottom maze in the shortest period of time. 
       BRIEF SUMMARY OF THE INVENTION 
       [0027]    An object of the present invention is to provide a three dimensional puzzle maze played as an individual skill puzzle or a competitive game comprising a two-sided maze structure with a different maze on each face of an opaque planar playing board with a middle barrier in each maze on each face dividing each face into two adjacent visible mazes with no passageway from one to the other and with openings through the playing board between the two faces requiring a user to tilt the playing field to roll a ball through each of the mazes and drop the ball from a top face to a bottom face and back and forth repeatedly with only one face visible to a player at a time requiring the player in order to pass from a starting indentation at one end of a top maze and land the ball in a finish indent in an opposite end of the bottom maze in the shortest period of time, which three dimensional puzzle maze may be played on a hand-held, double-faced casing with a transparent cover over each face manipulated by hand or mechanical means or on an electronic simulation of the same structure in a hand-held device or viewed on a screen. 
         [0028]    In brief, an opaque planar playing board with a different maze on each face is fabricated by molding or machining a synthetic or natural material to form the two-sided playing board or to create two different planar maze structures with a maze on one side and flat on the other and securing the flat sides together by conventional means such as using an adhesive or a heat staking process or using mechanical fasteners or by enclosing the two different planar maze structures in a sealed casing. The maze structures may also be constructed on each of two sides of a single flat opaque board or on two boards connected together. The mazes are configured to allow a sphere to roll on the planar playing board through the maze. Holes are drilled or formed in the planar playing board at various locations on the mazes to allow the sphere, a metal or other type of ball, to pass through the holes from one maze face to the other. A transparent cover over each of the two maze faces may be attached over maze configurations with elevated edges or the transparent cover may be part of a casing housing the opaque double-sided maze. The transparent cover retains the ball within each of the maze structures along with elevated edges around the mazes and also enables a user to view one face of the maze at a time. The same configuration and playing characteristics may be simulated electronically in a hand-held device with a viewing screen on two opposing faces and manipulated in the same fashion as the physically constructed, encased maze puzzle or with the two-sided maze puzzle simulated and the motion of the simulated casing viewed on a game screen or computer screen or television screen and played by using electronic control means. 
         [0029]    Alternately, a virtual playing board with virtual opposite face maze structures and virtual playing piece is displayed on a screen of an electronic device. A hand-held electronic device with internal motions sensors can be used by tilting the hand-held electronic device to electronically activate the electronic controls to simulate the motion of the virtual playing piece through the virtual mazes. A hand-held electronic device with both a top and a bottom screen shows the two virtual mazes in a similar fashion to a physical version of the invention and must be turned over in a similar fashion when the virtual playing piece travels through a virtual opening from one virtual maze structure to the other. A hand-held electronic device with a single screen can automatically change the image of the virtual mazes each time the virtual playing piece passes from one virtual maze structure to the other. 
         [0030]    An electronic device, such as a computer or gaming console, has a stationary viewing screen showing a virtual case housing the virtual playing board with two opposing virtual maze structures to tilt on a stationary screen operated by controls, which may be one or more joy sticks, to cause a virtual playing piece to traverse the maze structures. When the virtual playing piece passes from one virtual maze to the other, a player must manipulate the controls to flip the virtual case over on the screen to view the virtual maze structure containing the virtual playing piece.

         [0044]    In  FIGS. 1-5 , a playing board  20  comprises an opaque planar surface having two opposing faces  21 A and  21 B and a maze structure  23 A and  23 B on each of the two opposing faces of the playing board  20 . Each of the maze structures  23 A and  23 B comprises spaced walls  26 A and  26 B in various orientations and of various lengths to create passageways along the playing board  20  between the spaced walls  26 A and  26 B with some dead end passageways and some through passageways communicating with other passageways. 
         [0045]    In  FIGS. 1-5 , a playing piece (or ball or sphere)  30  moves on the playing board  20  through each of the maze structures  23 A and  23 B along the passageways, the playing piece moving in a direction of a downward tilting of the playing board  20 . The playing board  20  has a plurality of openings  25  therethrough at various locations to admit the playing piece  30  to pass from a first maze structure  23 A on a first face  21 A on one side of the playing board to a second maze structure  23 B on a second face  21 B on the opposing side of the playing board  20  and back. The playing board  20  also comprises edge walls  27  around the outer perimeter of each face  21 A and  21 B to define the peripheral edge limitations of the maze structure  23 A and  23 B. 
         [0046]    A start location  22  at a first end  11  of the playing board  20  in the first maze structure  23 A on the first face  21 A is the location for placing the playing piece  30  to start the passage of the playing piece  30  in motion, A finish location  28  at a second end  12  of the playing board  20  in the second maze structure  23 B on the second face  21 B is the final resting place of the playing piece. 
         [0047]    Each of the maze structures  23 A and  23 B has a barrier wall  24 A and  24 B extending between the two longer opposing side walls and midway between two ends of each of the maze structures  32 A and  23 B to prevent the playing piece  30  from moving directly from one end  11  of each of the maze structures  23 A and  23 B to the other end  12  of the same maze structure on the same face. The barrier wall  24 A and  24 B on one face  21 A is positioned out of vertical alignment with the barrier wall on the other face  21 B, thereby requiring the playing piece  30  to pass back and forth through various openings  25  between the maze structures  23 A and  23 B on the two faces  21 A and  21 B and traverse the maze structures  23 A and  23 B in order to move from the start location  22  in the first maze structure  23 A on the first face  21 A to land on the finish location  28  in the second maze structure  23 B on the on the second face  21 B at the opposing end of the planar playing board  20 . 
         [0048]    The object of the game is to tilt the playing board  20  in various orientations to cause the playing piece  30  to traverse the maze structures  23 A and  23 B and to travel through any of the openings  25  to pass between the two maze structures  23 A and  23 B, requiring the opaque planar playing board  20  to be turned over each time the playing piece passes from one maze structure  23 A and  23 B on one face to the other maze structure  23 A and  23 B on the other face in order to view the face and to cause the playing piece  30  to travel from the start location  25  to the finish location  28  in the fastest time. 
         [0049]    In  FIGS. 1-5 , the maze puzzle game  10  comprises a rigid planar board  20  having a rigid maze structure  23 A and  23 B on each face housed in an enclosed case  27  having a transparent cover  29 A and  29 B (in  FIG. 3 ) over the top of each of the maze structures  23 A and  23 B to prevent the playing piece  30  from escaping up out of the top of the maze structure  23 A and  23 B and to prevent the playing piece from jumping over the walls  26 A and  26 B and to allow a user to view only one maze structure  23 A or  23 B on one face of the playing board at a time, when the case is held in at least one hand of a user and tilted and turned over manually. 
         [0050]    In  FIGS. 1-5  the playing piece  30  comprises a rolling object to travel through the maze by the force of gravity, wherein the playing piece comprises a sphere.

The planar electronic case  50  is held in at least one hand of a user and the case is tilted manually to activate the motion sensors which activate the electronic controls to move the playing piece  30 A through the mazes to simulate the motion of an actual physical playing piece  30  (in  FIGS. 1-5 ) in response to gravity, including falling from one maze structure  23 A or  23 B to another maze structure  23 A or  23 B through the openings  25 , causing the virtual image of one of the maze structures  23 A or  23 B to appear to flip over to present the other of the maze structures receiving the virtual image of the playing piece  30 . 
         [0054]    In  FIGS. 10 and 11 , the maze puzzle game  10 C is played on a computerized electronic device  60  comprising a programmed electronic control  62  communicating with a stationary viewing screen  61  for creating an image of the virtual case  20  on the stationary viewing screen showing a visual image of the maze structures  23 A and  23 B one at a time. The electronic control  62  is operated by a user to tilt the virtual image of the virtual case  20  on the stationary viewing screen  61  to simulate the tilting of an actual physical case and move the virtual playing piece  30 A through the virtual mazes  23 A and  23 B to simulate the motion of an actual physical playing piece  30  (in  FIGS. 1-5 ) moving through the physical maze structures  23 A and  23 B (in  FIGS. 1-5 ) in response to gravity, including falling from one virtual maze structure  23 A or  23 B to another virtual maze structure  23 A or  23 B through the virtual openings  25 . The user is required to manipulate the controls  62  to turn over the virtual case  20  to view the virtual maze structure  23 A or  23 B containing the virtual playing piece  30 . 
         [0055]      FIGS. 10 and 11  show the maze puzzle game  10 C with electronic controls  62  comprising at least one joy stick. 
         [0056]    In a preferred embodiment of the physical hand-held maze puzzle game  10 , as shown in  FIGS. 1-5 , the three components comprise the playing board  20  with built-in maze structures  23 A and  23 B on opposing faces, as well as built-in edge walls  27 , a ball  30 , and two clear lens covers  29 A and  29 B, as shown in  FIG. 3 . The ball is preferably approximately ¼ inch diameter or less depending on the size of the playing board  21 A and  21 B, maze structures  23 A and  23 B, and openings  25  which would be limited in size for a hand-held case. The elements can be made of plastic, glass, or of a metal material. 
         [0057]    The center two-sided maze piece which will contain the actual mazes or maze structures  23 A and  23 B, passages  25 , and the two start/stop locations  22 / 28  may be milled utilizing a solid piece of nylon or similar material. The preferred approximate dimensions are 3 and ⅝ inches wide by 8 and ⅛ inches long and ¾ inches thick. A ⅜ inch wide end mill may be utilized to cut the maze channels to no less than a 5/16 inch depth on each side of the solid block. The holes  25  may be drilled through the block with a 17/64 inch drill bit to allow passage from one maze structure  23 A or  23 B to the other, and a 5/16 inch drill bit is used to counter sink an inset for the two start/stop positions  22 / 28 . The counter sink cannot go through from one plane to the other. Also a vent hole in each end of the block should be made using a 1/16 inch drill bit to keep the case from clouding up. A thin clear lens material may be cut to size and glued to each side of the maze block after installing the ball. 
         [0058]    An alternative to milling a solid material is to utilize a mold or molds to create the maze block from a plastic material. 
         [0059]    In use, present invention is a unique puzzle utilizing a network of passages and pathways with two adjoining planes on opposing faces of the playing board. There is a color coded start/stop  22 / 28  position inset in each of the two planes. The objective of the puzzle is to locate the ball  30  in one of the two start/stop positions, and then as quickly as possible try to relocate the ball to the other color coded start/stop position on the other side of the board. After completing the maze, the stop (or finish) position becomes the start position and the player tries to relocate the ball back to the original start position that then becomes the new stop or finish position. Several puzzles can be utilized by several players to race and determine the quickest player.
