Infinite Tic Tac Toe
In Infinite mode your oldest mark vanishes when you place a 4th, so the board never fills up and every game has a winner. Play the AI or a friend. Offline, no account.

Each player keeps at most 3 marks. Place a 4th and your oldest mark vanishes. The board never fills up, so a game never ends in a draw. Play against the AI or a friend.
Adaptive difficulty from Easy to Medium to Hard. Win and the AI levels up. Hard never makes a mistake, so can you hold it to a draw?

Each player can have at most 3 marks on the board. When you place a 4th, your oldest mark disappears. Because the board never fills up, Infinite games never end in a draw. You can play it against the AI or with a friend.
Yes, Tactix is free to download and play. It shows a banner ad and optional rewarded ads for extra Hints, extra Undos, and Second Chance (after losing to the AI, watch an ad to undo your last move and keep playing, once per game). A one-time purchase of $0.99, Tactix Pro, removes ads, gives unlimited Hint, Undo and Second Chance without ads, and unlocks the exclusive Neon mark style.
Yes. Every mode works without an internet connection, and no account is needed. Scores and settings stay on your device. Ads need a connection to load.
