Abstract
Abstract A chess game wherein the pawn, bishop, and rook pieces are typically circular in shape and have an arrowlike designation on the top face thereof, which indicates the permissible direction or directions in which the piece can be moved. One feature of the game is that in addition to being able to move a piece from the square which it is currently occupying, it is also possible to execute a rotational move only with one of the above pieces. In one form the rotational pieces have octagonal projections engaging octagonal recesses on the board. In a simpler form, the weight of the piece holds it in its rotated position.

Claim 1
Independent Claim
276 words
In an improved chess game comprising (1) a playing board including a matrix of playing spaces, and (2) playing pieces consisting of for each side eight pawns, two rooks, two knights, two bishops, a queen, and a king, the improvement comprising said pawns, bishops, and rooks each having a designation thereon indicating the permissible direction or directions in which the piece can be moved from one of said playing spaces to another one of said plaYing spaces and means for maintaining said piece on said one playing space in any selected one of a plurality of permissible angular positions on said playing board, said designation including a pointer in alignment with said another one of said playing spaces when said piece is in said one angular position where the designation of each pawn includes one and only one pointer indicating that said pawn can be moved from said one space to said another space where said another space is pointed to by said pointer, where the designation of each bishop includes two and only two oppositely directed pointers indicating that said bishop can be moved from said one space to said another space where said another space is pointed to by one of said two pointers, and where the designation of each rook includes two and only two pairs of pointers, the pointers of each pair being oppositely directed and the first pair being orthogonally disposed with respect to the second pair, indicating that the said rook can be moved from said one space to said another space where said another space is pointed to by one of said pointers of said two pairs of pointers.

Claim 3
Dependent Claim
55 words
The improvement of claim 1 where said means for maintaining said piece in said one angular position comprises an octagonal portion connected to said piece and an octagonal hole disposed in said one playing space whereby said octagonal portion mates with said octagonal hole to permit only 45* positioning increments or an integral multiple thereof.
Claim 4
Dependent Claim
37 words
The improvement of claim 1 where said means for maintaining said piece in said one angular position comprises the body of said piece whereby the mass of said body maintains said piece in said one angular position.
