DuoXO: Tic-Tac-Toe

Challenge the AI or play together on one device. Make every round your own.

One more round? DuoXO brings tic-tac-toe to your phone with quick matches, playful animations and clear, comfortable controls.

PLAY YOUR WAY • Challenge three AI levels: Easy, Medium and Unbeatable. • Play with a friend on the same device. • You start the first round; rematches alternate the starting player. • Play offline, without an account.

A LITTLE STRATEGY, A LOT OF FUN Plan your next move, block your opponent and go for three in a row. Follow your local wins, draws and losses, then jump straight into a rematch.
