Abstract
Abstract A board game comprising a multiple layer game board the top two layers of which are separable but maintained in registration and several sets of playing pieces, each set distinguishable from the other. The top layer is transparent and has an array of playing positions marked on it. The second layer carries indicia which can be seen through the top layer and which influence the placing of playing pieces on the game board in accordance with the rules. The third layer and the playing pieces are magnetically attracted to one another thus securing the pieces placed on the game board against moving out of place. The playing pieces are stackable and a stacked piece is mechanically or magnetically secured to the piece upon which it rests. The game played in accordance with the rules described is a remarkable simulation of auto racing and closely duplicates the physical laws of motion and the natural effects of speed, acceleration and momentum. The separable layers of the game board provide for interchangeable race tracks to add variety to the game. In addition, flexible barriers which interact magnetically with the game board can be placed on the surface of the board for rapid design of new track configurations by the players.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
271 words
Competitive game apparatus comprising: a plurality of sets of playing pieces, each one of said plurality of set of playing pieces having a plurality of playing pieces which have a common characteristic which distinguishes them from the plurality of playing pieces of every other set of said plurality of sets of playing pieces; stacking means included by at least some of said playing pieces whereby said stacking means permits one of said playing pieces to be stacked upon another and said stacking means also tends to prevent lateral movement of such stacked playing pieces relative to one another thereby tending to prevent an upper playing piece from falling off of the playing piece upon which it is stacked; a multiple layer game board, having a top layer which is essentially a flat sheet made of transparent material, at least one second layer which is essentially a flat sheet located beneath said top layer, and a third layer which is essentially a flat surface located beneath said second layer, said top layer and said at least one second layer being separable; a first indicia, which designates the playing positions, carried by said transparent top layer; a second indicia carried on at least one surface of said at least one second layer, said first indicia being different from any part of said second indicia and said second indicia being visible through said transparent top layer and influencing the placing of said playing pieces on said multiple layer playing board in accordance with the rules of the game being played; magnetic means which provides magnetic attraction between said playing pieces and said third layer.
Claim 2
Dependent Claim
271 words
Competitive game apparatus comprising: a plurality of sets of playing pieces, each one of said plurality of set of playing pieces having a plurality of playing pieces which have a common characteristic which distinguishes them from the plurality of playing pieces of every other set of said plurality of sets of playing pieces; stacking means included by at least some of said playing pieces whereby said stacking means permits one of said playing pieces to be stacked upon another and said stacking means also tends to prevent lateral movement of such stacked playing pieces relative to one another thereby tending to prevent an upper playing piece from falling off of the playing piece upon which it is stacked; a multiple layer game board, having a top layer which is essentially a flat sheet made of transparent material, at least one second layer which is essentially a flat sheet located beneath said top layer, and a third layer which is essentially a flat surface located beneath said second layer, said top layer and said at least one second layer being separable; a first indicia, which designates the playing positions, carried by said transparent top layer; a second indicia carried on at least one surface of said at least one second layer, said first indicia being different from any part of said second indicia and said second indicia being visible through said transparent top layer and influencing the placing of said playing pieces on said multiple layer playing board in accordance with the rules of the game being played; magnetic means which provides magnetic attraction between said playing pieces and said third layer.
Claim 3
Dependent Claim
53 words
Competitive game apparatus as set forth in claim 1 further comprising: flexible barrier means which comprises long thin strip means made of flexible material, said flexible barrier means constructed so as to interact magnetically with said third layer so as to experience magnetic attraction between said flexible barrier means and said third layer.
Claim 4
Dependent Claim
31 words
Competitive game apparatus as set forth in claim 1 further comprising: register maintaining means which prevents substantial lateral shifting of said top layer and said second layer relative to one another.
Claim 5
Dependent Claim
26 words
Competitive game apparatus as set forth in claim 1 further comprising: at least one additional second layer having at least one side which has no indicia.
Claim 6
Dependent Claim
70 words
Competitive game apparatus as set forth in claim 1 further comprising: a plurality of said second layers, more than one of said second layers having second indicia on at least one surface, each of said second indicia of said plurality of second layers being different and said plurality of second layers being interchangeable so that each one of said plurality of second layers may be placed beneath said top layer.
Claim 7
Dependent Claim
21 words
Competitive game apparatus as set forth in claim 1 wherein: said stacking means comprises magnetic attraction means between said playing pieces.
