Snakes & Ladders in Aquarium

Players spin the dice and move their character for the number of steps indicated by the dice. If they land on the lower-numbered end of the block with a "ladder", they can move their way up to the higher-numbered block. If they land on the higher-numbered square of a pair with a "snake", they must move their character down to the lower-numbered square. The first player who successfully arrives at the last block in an exact number of steps is the winner.
