Dice Chess - Rules

Rules

The players alternate rolling the dice and, if possible, moving. On each of the dice, the one represents a pawn, two a knight, three a bishop, four a rook, five a queen, and six a king. The player may move either of the pieces indicated on the two dice. For example, a player rolling a one and a two may move either a pawn or a knight. A player who rolls doubles (the same number on both dice) may play any legal move. Otherwise, standard chess rules apply, with these exceptions:

• a player who has no legal move with either of the pieces indicated by the dice loses that turn (passed turn);
• if castling is otherwise legal, a player may castle upon rolling a four, six, or doubles;
• an en passant capture of a pawn is possible only if the player rolls a one, or doubles, immediately once the opportunity for the en passant capture arises;
• a player who is in check can only play a legal response to that check (capturing the checking piece, moving the king, or interposing a piece);
• a player who is in check but does not make a roll allowing a legal response to the check loses that turn, but does not automatically lose the game;
• except in the unlikely event that the game ends in a draw pursuant to the standard rules of chess, the game ends when one player either checkmates the opponent or captures the opponent's king.
