Waraporn Khamsuk creates challenging tic-tac-toe. Handcrafted from a rain tree, the game features a square board with nine standing pegs for the addition of complementary X and O shapes. Just like traditional tic tac toe, the goal is for one of two players to arrange their shapes three in a row. With this game, however, the rules of the old pastime are brought into a three-dimensional space, fun for the whole family.
