This game comes as five dice packaged in a tube with a short page of game rules. The ones on the dice are replaced with lobsters.
In the first game (just called "A Lobster Dice Game") players must successfully molt their lobsters by rolling the dice. Unsuccessful players are out of the game, and the last lobster to molt is declared largest and wins.
In the second game ("Lobster Fishing") the players score one point for each lobster of legal size caught (i.e., a lobster rolled along with a 4, 5 or 6.) After 10 rounds of fishing, the winner is the one who caught the most lobsters legally.
