Frequently asked questions

How is this different from normal tic-tac-toe?
The win/lose condition is reversed: the player who completes three in a row is the LOSER, not the winner.
Is the AI beatable?
Yes — the AI uses simple heuristics, not a perfect minimax, so a careful human player can outmanoeuvre it.
