Swap the Shells to Solve this Memory Puzzle! You may be familiar with the classic shell game where the “shuffler” tries to trick his or her spectators into thinking an object is hiding under one “shell” or “cup” rather than another. In most instances, no matter how hard you focus, getting the right answer seems to be a gamble. In our twist on this classic, we use Sea Shells and Hermit Crabs. The goal is not to deceive, but rather to improve your memory and logic skills to help you win. Ages: 8 to adult Players: 1
