Tic tac toe, rebuilt. A neon board, an AI that actually plays well, and everything runs offline.
PLAY AGAINST A REAL AI
Three opponents, not one. Chill blunders and lets you breathe. Sharp punishes lazy moves. Ruthless plays perfect minimax — it has never lost a game and never will. You cannot beat it. Hold it to a draw and the app counts it as the milestone it is.
TWO PLAYERS, ONE PHONE
Pass & Play for you and a friend on a single device. The first move alternates every round so nobody keeps the advantage, and the series score stays on screen.
BLITZ MODE
Five seconds per move. Miss the clock and the board plays a random cell for you. Fast, loud, unfair in the best way.
TRACK EVERYTHING
Wins, draws and losses for each difficulty. Win rate, current streak, best streak, and how many times you held Ruthless to a draw.
BUILT TO FEEL GOOD
Animated X and O strokes, a neon line that snaps across your winning row, confetti, haptics on every move, and three themes: Neon, Sunset and Mono.
NO NONSENSE
No ads. No accounts. No tracking. No internet permission at all — the app cannot phone home even if it wanted to. Everything you play stays on your device.
Also known as noughts and crosses, XO, or three in a row. However you call it, it is here — and it is finally worth playing more than once.
