A-mazing rooks

Material: a double 6 dominoes set (with gaps separating the halves of each domino), a pair of rooks of different colors, a rectangular board and two rings.

Rules: the players set the dominoes randomly upon the board, and choose their departure and arrival squares upon the opposite edges of the board. Then they move their rooks each turn accordingly to the number of steps indicated by the domino upon which their rook sits, changing direction each time they meet a gap. First player either to reach his arrival square, block his opponent from moving or capture the opposing rook wins the game.
