Crowded Waters

Each player places a shark tile of his color on a designated starting space on an 8X8 board. On his turn, a player "moves" his shark by placing another tile of his color on the space next to his previously placed tile to which that earlier tile points. The newly placed tile may point in any direction, except to a space that another shark already points to or to an occupied space. Players eventually will get hemmed in and will be unable to move. Last shark standing or, rather, swimming wins.
