About Nought Tactics

The three-by-three grid you already know, paired with an opponent that plays it perfectly on hard — a full search of the game tree, no shortcuts. Every hard game you do not lose is a draw well earned. Normal makes occasional human mistakes if you would rather actually win sometimes.

How to play

• Take turns claiming squares; three in a line wins.
• Hard is unbeatable by design, so a draw is the best result available.
• Wins, draws and losses are tallied for the session.

Tips from the people who built it

• Open in the centre. It sits on four of the eight winning lines.
• If the computer opens in the centre, answer in a corner, never an edge.
• Watch for forks — one move that creates two threats is the only way to win.
