the present invention comprises the concept of a strategy game comprising game pieces that can be moved into different positions on a game board and have one or more “ solution positions ,” which are visually distinguishable from “ non - solution positions .” the games of the present invention can be single or multiple player games . each player &# 39 ; s respective game pieces are preferably visually identical to each other on surfaces that are visible to the player during game play , when the pieces are on a non - solution position . each player &# 39 ; s game pieces provide a visual indication that a particular piece is in a potential solution position — i . e ., by sitting higher or lower on the game board , or by illuminating the game piece . preferably , each game piece will provide the visual indication in both the solution position and some non - solution positions ( hereinafter “ ambiguous positions ,” which are a subset of the non - solution positions for each game piece ). therefore , the only way for a player to confirm that a game piece is a solution position is when all of the game pieces are simultaneously providing the visual indication that they are in a potential solution position . fig1 & amp ; 2 show a first embodiment of a game 10 of the present invention . in this embodiment a rectangular board 12 has depth to allow reception of the game piece 26 shown in fig3 and to be described in greater detail herein . in this embodiment , two rows of five equally spaced holes are provided , all having the same diameter as the first hole 14 . each hole includes a cylindrical peg centered therein . the holes in each row each include a peg having a different diameter . in this embodiment , the pegs 16 , 18 , 20 , 22 , 24 in each row have decreasing diameters from left to right ( as oriented in fig1 ). fig3 shows a game piece 26 for use with the game 10 . game piece 26 has a generally circular base 28 and profiled body , a shaped upper portion 30 , shown in this embodiment as spherical , and a height great enough to allow easy grasp by a player . the upper portion shape 30 could be any of many other shapes conducive to manual manipulation by the game 10 player . referring to fig4 , cross - sectional views of the five nearly identical game pieces 26 - 26 d , chosen to illustrate this embodiment , are shown . each of the game pieces 26 - 26 d has a similar base and profile shape 28 , upper shaped portion 30 and height . each game piece 26 - 26 d is differentiated from the others by the diameter of the holes 32 - 40 in the base 28 . the holes 32 - 40 are progressively smaller in diameter as shown and fit closely on the pegs 16 - 24 in the board 12 shown in fig2 . therefore , each game piece hole 32 , 34 , 36 , 38 , 40 has a “ matching ” peg 16 , 18 , 20 , 22 , 24 — i . e ., a peg 16 , 18 , 20 , 22 , 24 that is slightly smaller than the hole 32 , 34 , 36 , 38 , 40 . hole 32 matches with peg 16 , hole 34 matches with peg 18 , and so on . in accordance with the present invention , the game pieces 26 - 26 d are indistinguishable from each other , except for a portion that is not visible when the game 10 is being played properly ( i . e ., not inverting the pieces 26 - 26 d during play ). the components of game 10 shown in fig1 - 4 could be fabricated from wood or machined from common metals , but the board 12 and game pieces 26 - 26 d are preferably made from a polymer , such as polyethylene or polycarbonate , which can be injection molded to provide the precision , as molded , detail required . game 10 is , in this embodiment , a game played between two players who alternate moves of game pieces 26 - 26 d ( each player &# 39 ; s pieces being the same color , but different from the color of the other player &# 39 ; s pieces ) until one player has his or her respective game piece holes 32 , 34 , 36 , 38 , 40 positioned on its matching peg 16 , 18 , 20 , 22 , 24 ( this will be referred to herein a “ solution position ”). a player can tell if all of the game pieces 26 - 26 d are in the solution position if none of the five game pieces 26 - 26 d is elevated — meaning that its respective hole 32 , 34 , 36 , 38 , 40 doesn &# 39 ; t slide over the peg 16 , 18 , 20 , 22 , 24 . if a game piece 26 - 26 d is elevated on the board 12 , the piece 26 - 26 d is situated on top of a peg 16 , 18 , 20 , 22 , 24 that is larger than the hole 32 , 34 , 36 , 38 , 40 on the bottom of the game piece 26 - 26 d . if a game piece 26 - 26 d is leveled ( i . e ., not elevated ), it is either in the solution position or situated on a peg 16 , 18 , 20 , 22 , 24 that is smaller than its hole 32 , 34 , 36 , 38 , 40 ( ambiguous / potential solution position ). typically , the game pieces 26 - 26 d would be placed randomly on the board . there are many different configurations that could be used to start a game and many different variations of rules for playing the game . for example , the game could be started by randomly positioning the game pieces 26 - 26 d three of the same and two opposing colors in alternating array , on the board 12 such that a player has only two of their own color on their side of the board . a player &# 39 ; s turn allows switching of one of their own game pieces 26 with another of their own or the opponent &# 39 ; s without moving the opponent &# 39 ; s piece 26 to the player &# 39 ; s side of the board 12 . in this embodiment the game is solved or won when all of a player &# 39 ; s game pieces 26 - 26 d are correctly positioned to fit on the pegs 16 - 24 in the board 12 . thus all game pieces 26 - 26 d are fully recessed into the holes 14 of the board 12 . if the player who started the game 10 finishes first , the opponent may have one more move to tie . the game 10 also finishes in a tie also if the last exchange of game pieces 26 makes both sides positioned correctly . fig5 - 8 illustrate an embodiment of another game 110 that may involve visually identical or indistinguishable playing pieces 126 depending upon the desired level of difficulty and the intentions of the inventor . fig5 is a player &# 39 ; s view of the game 110 . for this embodiment , a four by four array of game pieces 126 is shown in position on the board 112 with all sixteen game pieces a single color . two game pieces 126 a , 126 b are shown in a raised position which will be explained below . the number of game piece positions on the board 112 equals the number of game pieces 126 utilized . in fig6 , two game pieces 126 are removed from the board 112 to show differing peg patterns 116 , 118 in the board 12 and hole patterns 132 , 134 in the game pieces 126 c , 126 d . the hole patterns 132 , 134 in the game pieces 126 c , 126 d are different , but match and fit into the peg patterns 116 , 118 respectively in the board 112 . the game pieces 126 have a square , equal side length , base which allows any game piece 126 to rest in four positions rotationally on the board 112 . the differing peg patterns 116 , 118 enable two visually distinguishable positions of an individual game piece on the board 112 . specific game pieces 126 a , 126 b are shown in the “ up ” position ( indicating a non - solution position ) while all others 126 are shown in the “ down ” ( indicating a solution position or an ambiguous position ). in this embodiment , for a specific game piece 126 in a board 112 location with a compatible peg pattern 116 , 118 there is only one “ down ” position , but three possible “ up ” positions depending upon its rotational orientation . if the game piece 126 is positioned in a location with an incompatible peg pattern 116 , 118 all four possible rotational positions will result in the game piece in the “ up ” position . in other embodiments , a specific game piece could have more than one compatible peg pattern , which would decrease the level of difficulty . the single color game pieces 126 shown in fig5 illustrate a single player version of the game 110 . to begin the game the game pieces 126 are randomly located on the board 112 . for a move the player either exchanges location between two game pieces 126 or changes the rotational position of a game piece 126 . the movement of game pieces 126 continues until all of the pieces 126 are a solution position . a player is not allowed to look at the bottom of game pieces during play . the object would be to reach the solution position with all game pieces 126 in the shortest time or with the fewest number of moves . typically reaching a rapid solution requires the player to remember peg pattern 116 , 118 locations as well as game piece 126 hole patterns 132 , 134 rather than making random moves . the level of difficulty of game 110 can be increased depending upon a number of variables . for instance , this embodiment has been described as utilizing a board 112 with two distinct peg patterns 116 , 118 . it can be understood that the solution difficulty increases if the number of peg patterns 116 , 118 were to increase . also increasing the size of the board 112 and the corresponding number of game pieces 126 required could have a similar result . the details and fit required between the board 112 and the game pieces 126 would likely result in these parts being manufactured as molded polymer parts . as in the first embodiment , a polymer such as polyethylene or polycarbonate could preferably be used in an injection molding process to economically produce large volumes of consistent , precision parts . the size of game pieces 126 and board 112 is chosen to be appropriate for the intended end use , i . e . pocket or table use , and to provide for ease of player manipulation of the pieces 126 . fig7 & amp ; 8 illustrate some example variations that can provide other embodiments of the game 110 . fig7 shows game pieces 126 with one side in a different color . game pieces 126 colored in this way could be used to indicate hole pattern 132 , 134 orientation and aid the player in making moves toward a solution . fig8 shows game pieces 126 with a colored top surface . splitting the game pieces 126 into two groups using the differentiating top colors would allow two players to participate competitively . as in the original embodiment , the number of peg patterns 116 , 118 in the board 112 and corresponding hole pattern 132 , 134 in the game pieces 126 could be varied to provide a desired difficulty level . one way the two player game 110 could start would be with half of each color of game piece 126 distributed over the respective player &# 39 ; s side of the board . each individual player &# 39 ; s turn would involve the rotating in place or exchange of game pieces 126 between two positions . again a player may not move an opponent 3 s game piece 126 away from its side of the board 112 . the alternating repositioning of game pieces 126 would continue until one player has all their game pieces 126 in the solution position . the starting positions and / or move rules could be changed to provide variations of the game 110 utilizing the same board 112 and game pieces 126 . fig9 & amp ; 10 show a third embodiment of the present invention , which comprises a game that is an improvement of the puzzle disclosed in u . s . pat . no . 6 , 773 , 011 . fig9 is an exploded view of the pieces of an insert 232 that , together with other revised components of the puzzle disclosed in u . s . pat . no . 6 , 773 , 011 , comprise the game 210 . game 210 utilizes visually identical or indistinguishable playing pieces / inserts 232 that must be relocated by movement or rotation into a correct position in order to arrive at a solution . insert 232 and like inserts ( not shown ) are mechanically interchangeable with inserts 32 - 34 disclosed in u . s . pat . no . 6 , 773 , 011 and the new game 210 components are mechanically identical to the corresponding components in the referenced puzzle disclosed in u . s . pat . no . 6 , 773 , 011 except as otherwise disclosed herein . in fig9 , the insert 232 is shown comprised of an upper surface / disc half 274 , led / printed circuit board 282 with a light emitting diode 284 (“ led ”) and lower surface / disc half 276 . the upper surface 274 and lower surface 276 are preferably made of a polymer such as polyethylene or polycarbonate . the led / printed circuit board 282 is preferably made with flexible circuit board material with the led 284 attached to the top side and the contacts 286 , 290 protruding from the bottom of the board just enough to allow electrical continuity with the contacts 288 , 292 embedded in the lower surface 276 . the upper and lower surfaces 274 , 276 are snapped , adhered or otherwise mechanically fastened to each other to form the complete insert 232 which is spherical and symmetrically shaped . led / printed circuit board 282 is located by the led 284 cover and retained mechanically by being sandwiched in place between the upper and lower surfaces 274 , 276 . fig1 is a cross - section of a sphere / element 218 and the insert 232 described above . the sphere / element 218 is mechanically identical to spheres 18 , 20 , 22 , 24 disclosed in u . s . pat . no . 6 , 773 , 011 and inserts 232 are used in place of inserts 32 - 34 , but both have functional modifications that have been or will be described . there are four distinct locations for the versions of the contact 292 in insert 232 which correspond to four versions of the sphere / element 218 . referring to fig9 and 10 , contact 292 aligns with contact 296 labeled 2 in the recess 226 of the sphere / element 218 . the contacts in the other three recesses of sphere 218 are in the same location , thus the sphere 218 shown is dedicated to position 2 . in the other three versions , each dedicated to one of the contact positions 1 , 3 or 4 , the contact on the lower surface of the respective insert would align with the contact positions labeled 1 , 3 or 4 . in this way , the insert &# 39 ; s led would only have continuity to the contact in the sphere / element when positioned in the correct recess . each of the four sphere / elements is dedicated to a singular insert contact configuration . the contact 288 centered in the lower surface 276 of the insert 232 is the led 284 ground connection . it provides continuity through ground contact 294 centered in the recess 226 of the sphere / element 218 and with the ground connections similarly located in each sphere / element 218 recess 226 , 230 . this circuit connects to a power source , not shown , contained within the sphere / element 218 . the power source is preferably a small dry cell battery contained within the sphere 218 . each distinct recesses 226 contact 296 , labeled as 1 , 2 , 3 or 4 also connects with the battery power source , not shown . thus when any insert 232 is positioned in the recess 226 with an aligned contact 296 , the led 284 has electrical continuity with the power source and will light . the sphere / element 218 is preferably made of a polymer such as polyethylene or polycarbonate with the imbedded contacts 296 being circular to enable continuity with the lower surface contacts 292 in any rotational position of insert 232 . this embodiment of game 210 differs from the previously disclosed puzzle in that four sphere / elements 218 and three similar others , replace the sphere / elements 18 , 20 , 22 , 24 . insert 232 and two similar others replace the inserts 32 , 34 , 36 . the mechanical manipulations necessary to play the game 210 are the same , but the asymmetrical nature of the inserts 232 results in two passes being required to return the led 284 to an outward facing position . after randomly positioning the inserts 232 , the player moves them by rotation or passing them between sphere / elements 218 until all leds 284 are illuminated ( solution position ). thus the solution / game object is lighted leds rather than a color pattern such as a single color on each side of the case . for increased game solution difficulty or variety the leds could be different colors and / or the contacts in the sphere / element recesses could be scrambled . in addition , the electrical contacts 288 , 292 could be configured to illuminate the led 284 on a particular insert 232 when the insert is not in a solution position ( ambiguous / potential solution position ). while the principles of the invention have been described above in connection with preferred embodiments , it is to be clearly understood that this description is made only by way of example and not as a limitation of the scope of the invention .
a game having page pieces and a game surface including game piece receiving members . each of the first set of game pieces also includes a solution position and non - solution positions in which the game surface - engaging member is mated with one of the plurality of game piece receiving members . when a game piece is in a solution position it exhibits an indication , such as sitting lower with respect to the game surface or illuminating a light , which visually distinguishes the game piece from at least some of the game pieces which are in the non - solution position . aside from the visual indication , each game piece is visually indistinguishable from all other game pieces for each game player when the game pieces are located on the game surface in an upright position .
