There are 18 crabs on the beach trying to reach the other side of the board (made by a sort of leather). Your 9 crabs must be faster than the opponent's crabs. A crab cam move a space or jump over one or two adjacent crabs. Ending in a column with either one or three opposing crabs entitles you to an extra move.+ This is the game Sniggle from Sly, but only for two players.
