An abstract strategy game played on a 7x7 grid. Four starting spaces are marked in the four player colors. The object of the game is to visit each of the four colored spaces on the board, ending with the space of your own color. Movement is controlled by a pair of dice, one dictating which direction the piece must turn during the move, and the other setting the distance of the move.
