This is a great educational game that your tots will not be able to cheat at. Not that they intentionally cheat, they just can’t follow all the rules and wait for the next step. If you’ve ever played memory with a young tot, you know what I mean. The Cranium Cariboo has a key that the grown up holds on to and they can’t flip over their card without it because the card is attached to the game board. Underneath the board are balls that roll around so you never know where they all are. The objective is to find all the balls and put it in the track – once all the balls are in the track, the treasure box will open. It will not open without it. There are built in mechanisms to ensure that the game is played by the rules in an orderly fashion. At Amazon
