Everyone remembers the game Tic-Tac-Toe, but odds are you don’t play it much anymore.  There’s a good reason for this — most of us learned back in elementary school that the game is bound to end in a draw.  But as the great math puzzle guru Martin Gardner once said, “Many players have the mistaken impression that because they are unbeatable, they have nothing more to learn.” 




Join Yale professor Nathan Kaplan as he shows us that there is plenty more to learn about Tic-Tac-Toe.  Together we'll explore interesting strategies and investigate fascinating unsolved problems.  Who knew Tic-Tac-Toe could be this much fun?! 

Bring your strategic ‘A-game,’ and you’ll have the chance to become the Family Fridays Tic-Tac-Toe grand champion.

Recommended for ages 9 and up.
