Everyone knows tic-tac-toe. Everyone also knows that two people who know what
they are doing will draw every single time. XO Mini fixes that — with two rule
changes that turn a solved game back into a real one, and boards big enough to
think about.

THREE WAYS TO PLAY

Classic — the original. Take turns, line your marks up, and the first complete
row wins.

Misère — reversed. Completing a line LOSES you the round, so the whole game
becomes about avoiding one while pushing your opponent into making it. It feels
wrong for about three moves, then it feels brilliant.

Vanish — you only ever hold a few marks. Place a new one and your oldest
disappears, so the board never fills up and a round never grinds to a
stalemate. Position matters more than territory.

THREE BOARDS

3×3 — three in a row. Quick rounds, no room to hide.
5×5 — four in a row. Enough space to build two threats at once.
7×7 — five in a row. A single block no longer saves you.

PLAY A FRIEND, OR THE COMPUTER

Pass one phone back and forth for two-player games, or take on the AI at three
levels:

Easy makes mistakes you can punish.
Medium is solid, but not flawless.
Hard is perfect on 3×3 and ruthless on the bigger boards.

The AI plays every mode, and it understands each one properly — playing to lose
in Misère is a genuinely different problem from playing to win, and it adapts
to how fast your phone is so it always uses its full thinking time.

EVERYTHING ELSE

• A leaderboard for every mode, ranked by wins
• A How to Play guide with each mode shown in action
• Portrait and landscape, sized properly for small phones and tablets alike
• Music and sound effects, each with their own volume — or off entirely
• Sounds written for the game: X and O have their own note, so you can follow
a round without watching

PRIVATE BY DEFAULT

No account. No sign-in. Nothing to create. The game plays completely offline.

Your settings, the names you type and your leaderboard stay on your device —
they are not sent to us, and they are deliberately left out of Android's
automatic backup, so they never reach a Google account either. Uninstalling
removes them for good.

Free to play, with a small banner ad.
