Game 02

Tic-Tac-Toe

Choose your symbol, decide who starts, and challenge the computer. If your move is a real mistake, you will see a warning message: "perderai".

How it works

The computer uses full game-tree search for perfect play. You can configure first player and symbol before starting a new round. When the human player makes a suboptimal move, the page highlights it with the warning text "perderai". If the human loses, the computer celebrates on screen.
