Tic Tac Toe is the classic game of Xs and Os — now with a friendly robot opponent. Take turns placing your mark on a 3×3 grid; the first player to line up three in a row, column or diagonal wins. Play against a classmate on the same screen, or test your logic against three levels of robot.
About Tic Tac Toe
The Easy robot makes plenty of mistakes, perfect for younger children learning the rules. The Smart robot usually blocks you, and the Unbeatable robot plays perfectly — the best you can do against it is a draw! Can you prove it?
A running scoreboard counts wins for each side and draws, which makes Tic Tac Toe one of the best 2 player games unblocked for short tournaments during indoor recess.

Why play Tic Tac Toe? Benefits for kids
Logical thinking
Kids learn to look for winning moves and block their opponent — the basics of strategy.
Turn-taking
Playing with a friend practices patience and fair play.
Thinking ahead
Creating a "fork" (two ways to win) teaches planning more than one step ahead.
Sportsmanship
A score table invites friendly rematches and learning to lose gracefully.

🍎 Using Tic Tac Toe in the classroom
Use the Unbeatable robot as a challenge: can anyone in the class win? (They can’t!) Then discuss why perfect play always leads to a draw — a great introduction to strategy and game theory for older students.
