🧩 Noughts and Crosses

<p>The schoolyard classic reborn against a perfect computer mind, where every move must be calculated. Noughts and Crosses 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. Bite-sized rounds and steadily climbing scores give it that moreish, come-back-tomorrow quality that brain games live on. Wherever you play from, the experience stays fast, fair and frustration-free. There's nothing to install — it loads straight away in any modern browser and plays beautifully on touch or keyboard. 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. Beat a personal record and the built-in share buttons let you challenge a friend on WhatsApp or Telegram in one tap.</p>
