The dice have six symmetrical and square faces, the faces being marked with identifying designations resembling the profiles of different playing pieces of a conventional chess set. In one embodiment, a die has its six faces marked with symbols rcsembling the profiles ofa Pawn, Rook, Knight, Bishop, Queen and King, respectively. Each player alternately throws the dice and is permitted to move one of his own pieces corresponding to the symbol appearing on the upward face of either die, or if this is not possible, he can then move any oneof his other pieces. In an alternate embodiment, the dice each have one blank face, indicating a free move, whereby a player is permitted to move any one of his pieces when such a blank face has appeared on eitherof the throwndice. The permissible moves of each playing piece follow conventional chess rules.
1 Claim, 19 Drawing Figures CHESS GAME APPARATUS INCLUDING DICE FIG. 8 is a top plan view of a modified die, wherein BACKGROUND a designation representing the King has been included This invention relates generally to chess games, and more particularly to modifications of the game wherein an element of chance is introduced into play. The rules of conventional chess have remained fairly constant for hundreds of years. After prolonged periods of play, the game may tend to become monotonous and boring.
Also, heretofore the outcome of a contest between two players has almost entirely depended on the relative skill and playing experience of each. As a result, contests between players of widely varying chess backgrounds has tended to be rather one-sided and uninteresting. Also, due to the complex nature of chess, frequently play has tended to progress at a very slow rate, since after each move there are so many moving possibilities that confront a player.
SUMMARY The above disadvantages and drawbacks of conventional chess are obviated by the present invention, which has for its object the provision of a modified and improved chess game which results in greatly increased enjoyment by the players, while substantially reducing the playing time required. A related object is to provide a game as above characterized, which tends to equalize a contest between players of widely varying abilities and background, thus making the game more interesting and challenging to both. i
The above objects are accomplished by a novel, modofied chess game comprising a game board having 64 squares, a set of 32 chess pieces, and a set of dice, each die being in the form of a cube and having six symmetrical, square faces. The faces are marked with identifying designations representing some or all of the playing pieces of a conventional chess set. Five of the faces are marked with symbols representing respectively a Pawn, Rook, Bishop, Knight and Queen. The sixth face can alternatelyhave a-symbol representing the King, or another Pawn, or else can be blank. During play, each player alternately throws the dice, and is permitted to move one of his pieces corresponding to the designation on either of the two upturned faces of the rolled dice. The permissible moves of designated pieces are dictated by the conventional rules of chess.
Other features and advantages will hereinafter appear.

Referring to FIG. 1, in accordance with the present invention, there is provided a novel chess game comprising the combination of a chess board 10 having a plurality of squares 14 of alternating color and juxtaposed to one another, a set of chess pieces 16, and a pair of novel chess dice 68'and 20. Referring to FIGS. 2-7, according to one embodiment of the invention, the die 18 illustrated therein comprises a cube having six, symmetrical square faces 22, 24, 26, 28, 30 and 32, the faces 22, 24, and 28-32having identifying pictorial designations 34, 36, 38, 40 and 42 respectively corresponding to the playing pieces of a conventional chess set. As shown, the face 22 is marked with a profile outline of a Rook, to thereby represent the same; similarly, the faces 24, 28, 30, and 32 are marked to represent a Queen, a Pawn, a Bishop and a Knight, respectively. The face 26 is left blank, or alternately may have a symbol representing something other than achess piece, the purpose of which will be explained later.
Another embodiment of the invention is illustrated in FIGS. 8-13, showing a die 20 having faces 44, 46, 48, 50, 52 and 54, the faces having identifying designations 56, 58, 60, 62, 64, and 66v representing the chess pieces Rook, Queen, King, Pawn, Bishop and Knight, respectively. This embodiment differs from the embodiment of FIGS. 2-7 in that the blank face 26 of FIG. 4 in the first embodiment has been marked with a designation 60 representing a King, such that each of the six faces has a designation corresponding to a different one of the six different kinds of playing pieces which occur in a conventional chess set.
Still another embodiment of the invention is illus trated in FIGS. 14-19, showing a modified die 68 having faces 70, 72, 74, 76, 78 and 80.The face has a designation 82 representing the chess piece Rook, and similarly the remaining faces are marked with symbols 84, 86, 88, and 92 representing a Queen, at Pawn, another Pawn, a Bishop, and a Knight, respectively. The embodiment of FIGS. 14-19 differs from that of FIGS. 8-13 in that a Pawn (FIG. 16) has been substituted for the King (FIG. on one of the die faces.
Referring again to FIG. 1, the game is played on the chess board 10 having 64 squares 14 of contrasting color, each player having I6 pieces comprising eight Pawns, two Rooks, two Bishops, two Knights, one Queen and one King. To commence play, the pieces are arranged on the board in the conventional manner, and are permitted to move in accordance with conventional chess rules. Normally, two dice are employed, and for purposes of explanation it will be assumed that the die of FIGS. 8-13 and the die 68 of FIGS. 14-19 are employed. The first player to move rolls the dice before making his move. He is then permitted to move either of his own pieces corresponding to the symbols appearing face up on the rolled dice. The player must move one of these pieces, unless the standard rules of chess prevent such a move (such as would be the case if, for example, a Rook was cornered by two adjacent pieces). If neither of the pieces designated can be moved, the player then must move another one of his pieces. His opponent then rolls the dice and moves according to the same procedure. This process is continued throughout the game, with each player rolling the dice at his turn to determine which of his pieces he has the option of moving.
Castling is permitted whenever either a Rook or a King is rolled, provided that both pieces involved are posted in their original squ ares lf a players King is in check, he then foregoes rolling the dice at his turn and may move any of his pieces, one at a time, to overcome the check. Also, if either player has only his King left on the board, then rolling of the dice is dispensed with, and both players are free to move any of their pieces, alternately, one at a time.
Variations in the game are possible. If two identical dice 68 of the type illustrated in FIGS. 14-19 are employed, wherein the dice each have two Pawn designations and no King designation, the rules can be moditied to permit the King to move at any time, regardless of the results of the throw of the dice. Due to the large number of Pawns occuring in the game at the commencement thereof, it has been found desirable to employ at least one die with Pawn designations on two faces. In the case that the die of FIGS. 2-7 is employed, the blank face 26 can indicate that a free move is available to the player, wherein he can move any one of his pieces during his turn corresponding to that particular roll.
From the above it can be seen that I have provided a novel, modified chess game which greatly adds to the enjoyment and diversity of conventional chess. Unusual situations are created which require decisions by the players that are frequently different from those encountered in conventional chess. Since the range of allowable moves is narrowed during each players turn, play tends to be faster, and the effects of large differences in playing experience between the players tend to be minimized because the dice introduce an element of chance into the game. As a result, the level of strain for the average player is reduced, and his enjoyment of the game is enhanced. The game thu's represents a distinct advance and improvement in the field of chess and chess-like games.
Variations and modifications are possible without departing from the spirit of the invention.
