Can You Beat Perfect Tic Tac Toe AI?

If the AI is implemented correctly, you cannot beat it. You can draw it. That is not a taunt. It is a statement about a tiny, fully known game tree.

What a draw looks like

Every threat is blocked. The board fills. Nobody has three in a row. You did not fail. You played the correct game.

If you 'won'

• You were on Easy, which is random, not perfect.
• You played a local human who was not the computer.
• There is a bug — in which case we want to know, because Hard is tested against every possible human line.

Why we still ship Hard

Because 'can I force a draw?' is a fair challenge, and because it teaches the never-lose policy faster than a friend who lets you take the center every time. Start a Hard game, then read how to never lose if the first loss surprises you.
