    01 · The twist

    No black box

    Most tic tac toe bots just move. This one shows every square it considered, the outcome it expects from each, and a plain sentence on why it chose its move.

    02 · How it thinks

    Minimax, in short

    The AI plays out every possible game to the end. A win scores +10, a loss -10, a draw 0, and quicker wins score higher. It picks the square with the best guaranteed result.

    03 · Your record

    Can you beat it?

    On Unbeatable, the best you can do is a draw. On Friendly it sometimes slips, so you can win.
