XO Arena: 3D Tic Tac Toe

Four stunning 3D worlds, an unbeatable AI, and a twist: in Vanishing mode your oldest piece fades away. Tic-tac-toe has never looked, sounded or felt this good.

Tic-tac-toe, rebuilt from the ground up as a living 3D experience.

Every piece drops onto a real-time rendered board with glowing light, soft shadows and a satisfying bounce. Win, and your line bursts into a beam of light and a shower of confetti. Tilt your phone and the whole arena shifts with you.

FOUR WORLDS, ONE TAP AWAY • Neon Pulse – electric city nights • Crystal Dream – glass, light and prisms • Royal Marble – walnut, marble and gold • Fire & Ice – molten gold versus frozen crystal Switch themes mid-game and watch the board transform.

PLAY YOUR WAY • Solo vs AI – Easy, Medium, or Impossible (good luck) • Pass & Play – two players on one device • Nearby Duel – challenge a friend over Wi-Fi & Bluetooth, no internet or account needed

TWO RULESETS • Classic – the timeless 3×3 duel • Vanishing – each player keeps only three pieces. Place a fourth and your oldest one dissolves. No more draws, only pure strategy.

FEEL EVERY MOVE Hand-tuned haptics and a soundtrack that rises with every move make each placement feel alive.

No ads. No tracking. No sign-up. Just the best-looking game of X and O on your iPhone and iPad.
