This upgraded version of the classic Tic-Tac-Toe game from Giiker is smart enough to be challenging fun for adults and kids alike. Flip the switch on this compact yellow square to play Tic-Tac-Toe with a twist: your first X or O disappears once you place a fourth on the board. Play Infinite Tic-Tac-Toe against the device or switch to Head-to-Head Mode and play against a friend. Switch to Memory Mode to start a brand new game: press on the squares to follow the lights in sequence as they flash. Finally, you can pull open the box to play Cover-Up Tic-Tac-Toe: a physical game with blue and red pieces in different sizes that can cover each other up. As always, three in a row is a win! The Tic-Tac-Toe Bolt runs on two AA batteries (not included) and measures 2h x 3.5w x 3.5"d. For ages 3+.
