Zen Tic-Tac-Toe is a sleek, neon-styled take on the timeless strategy classic. Play against a smart AI opponent or challenge a friend in local two-player mode. The AI uses a neural decision tree to adapt its strategy — it blocks your winning moves, sets up traps, and forces you to think multiple moves ahead. Clean animations, satisfying win effects, and infinite replayability make this the most polished Tic-Tac-Toe available in a browser.

Desktop: Click any empty grid cell to place your symbol
Mobile: Tap any empty grid cell to place your symbol
vs AI: You play as X; the AI plays as O automatically after your move
