The game is played on a board divided into squares. One player is black, the opponent is red. Each has one starting square on each side of the board. At each turn, the player rolls three dice with black/red patterns on it: curves or bridges of both colors, or white crossings useful for both players. The player choose two dice to be placed on the board wherever he wants, building paths across the board. (The first player rolls two dice for the first two turns, to balance the starting advantage.) White crosses must be chosen. The player connecting his four starting squares wins. If in doing so he also connects his opponent's starting squares by mistake, he loses instead.
