Players have to collect four matching or one each of the four Teenage Mutant Ninja Turtles characters, to be first to take a shell. When the first shell is taken, all the other players try to quickly take a shell too. The player who fails to take a shell must cross out a "TURTLES" letter beside his name on the score sheet. The winner is the last player with "TURTLES" letters remaining on his scoresheet.
