Tic-tac-toe goes all the way back to the ancient Romans, who referred to it as terni lapilli (Latin for "three pebbles at a time"). We're pretty sure this 3D version would knock their sandals off. It reinvents the classic game with a mind-boggling peg design, complete with stackable X's and O's. Hand-carved from Indian rosewood, the pieces can be played vertically, horizontally, or diagonally, giving you endless ways to stump your opponent. Toga optional. Crafted in India by artisans who are part of the Fair Trade Federation.
