From the manufacturer:
"A fun strategy game for older players who like tic-tac-toe and checkers… One player is TOOT and the other player is OTTO. Each takes six O’s and six T’s. The first player who spells his or her name - up, down, sideways, or on the diagonal - wins!
“A fill & find game for younger players. Simply drop all the T’s and O’s in the tower and when it’s full, search for how many TOOT’s and OTTO’s you can discover!”
