🧩 XO Strategy Duel

<p>Hunt for the elusive fork and build your win streak against an AI that punishes the smallest mistake. XO Strategy Duel is noughts and crosses against a flawless AI that uses the minimax algorithm and never makes a mistake. Under the surface it's quietly training forward thinking, forks and defensive play. Because every session is brief but begs for 'just one more go', it's become a reliable daily habit for puzzle lovers. Wherever you play from, the experience stays fast, fair and frustration-free. Free to play and ready in a tap, it works the same whether you're on a laptop or a phone on the bus. There are no timers forcing you to rush unless the game itself adds one, so you can play at your own thoughtful pace. Controls are dead simple to learn but the depth keeps revealing itself the more you play. It sits comfortably alongside the other thinky games in our collection if you fancy a change of pace. Your best result is saved locally, so each visit you're really racing the toughest opponent of all — yourself.</p>
