Archimedes was a Greek mathematician, scientist and all-around uber-genius who discovered the laws of the lever, which in playground terms is basically a teeter-totter. Combining strategy, skill and a little bit of luck, the game consists of a wooden board that rocks like a teeter totter, a special die and 28 marbles. To be the winner in this best selling Marbles game, just be the first player to oh-so-carefully get four marbles to your end of the board without reaching the tipping point, causing it to touch the table. For 2 players ages 8 & up.
