Tic Tac Toe Pro

Tic Tac Toe Pro gives the familiar three-in-a-row contest a polished presentation and several ways to play. You can test your decisions against artificial intelligence with different skill settings or face a friend in a competitive match.

Each turn is a small strategic choice: claim a useful space, build your own line, and prevent the opposing side from completing one first. Its short board-based format makes every placement important.

Select an open space on the board with a mouse click or a tap to place your mark.

Take turns filling spaces while trying to form the winning line before the other player does.

Choose an AI skill setting when playing alone, or use the multiplayer option for a match against a friend.

Watch the developing rows, columns, and diagonals so your next mark serves attack or defense.
