This game is a close relative of the Slimetrail game. There are two players: red and blue snails. Initially snails are placed in the opposite corners of the rectangular board. The snails can be moved to adjacent cells and may not move to a cell occupied by the opponent's snail or re-visit a visited cell. The game ends up when one of the players cannot move his snail on his turn. The other player wins in this case. Usually played with progressive-moves variant.
