Tic Tac Toe is a two-player alignment game. Players alternately place marks on a three-by-three grid, aiming to create an uninterrupted line of three. The game highlights turn-based strategy, spatial reasoning, and equilibrium. It serves as a teaching example in computer science. Draws occur when no remaining moves yield a line.
This online version lets you play instantly without installation. Choose to face a second human or a computer opponent that never makes an error. Reset the board anytime, then share the current position through the address bar and resume on another device. Animated highlights make each winning line clear for observers.
You can embed the game in lessons to demonstrate optimal play, or use it during breaks for light competition. The AI illustrates perfect decision making, letting learners test strategies and discover forced draws. Quick links allow tournament organisers to record pivotal positions for later analysis.
