Think you're a master of strategy? Prove it in Tic Tac Toe IO—challenge friends, outwit the AI, and dominate the grid! Play now!

Tic Tac Toe IO is a sleek, modern take on the timeless game of Xs and Os—also known as Caro. With intuitive gameplay and strategic depth, it offers a fun and competitive experience whether you're playing solo, with friends, or against global opponents.

Gameplay and Modes

The core rules remain simple: two players take turns placing Xs and Os on a grid, and the first to align a straight line—horizontally, vertically, or diagonally—wins.

But Tic Tac Toe IO adds exciting variety with multiple game modes:

  • Online Mode: Compete in real-time against players from around the world.
  • Two-Player Mode: Share a screen with a friend and battle it out on different board sizes (3x3, 9x9, 15x15, or 21x21) with win conditions like 3 or 5 in a row.
  • Vs. Computer: Play against the AI at Easy, Medium, or Hard levels—great for practicing your tactics.

Controls

  • Mouse/Touch: Click or tap on the board to place your X or O.
  • Keyboard: In two-player mode, alternate turns using key inputs for a fast-paced local match.

Play Tips

  • Control the Center: Especially on 3x3 boards, the center offers the most strategic value.
  • Think Ahead: Always watch for your opponent’s potential moves and block them in time.
  • Bigger Boards, Bigger Brainpower: On larger grids, focus on building multiple lines to overwhelm your opponent.
