Unbeatable Tic-Tac-Toe

Latest version: v v2
App code: app30

Unbeatable Tic-Tac-Toe is a mobile-first, offline-ready HTML game designed to sharpen your Tic-Tac-Toe skills against a perfectly logical opponent. The computer uses a full minimax algorithm, evaluating all possible moves to ensure it never loses. If you play optimally, the best outcome you can achieve is a draw. This game is not about luck — it is about learning patterns, blocking strategies, and understanding why certain moves always fail. After playing a few rounds here, you will stop losing to friends, colleagues, and overconfident opponents who still play “by instinct”.
