Whether you are a beginner or a seasoned player, each grid offers a new level of challenge and fun.

How to Play

To start, choose your preferred grid size: 3x3 for a quick game, 5x5 for more complexity, or 7x7 for an ultimate challenge. In two-player mode, take turns placing your X or O on the grid. The first to get three in a row—horizontally, vertically, or diagonally—wins. In AI mode, you play against a smart computer opponent that adapts to your moves. Simply click or tap on an empty cell to make your move. The game highlights winning lines and keeps track of scores. No downloads or sign-ups are needed—just open and play!

Game Features

Multiple grid sizes allow players to choose their preferred difficulty. Two-player local mode is perfect for playing with a friend or family member. A computer AI opponent provides a challenging solo experience. The game automatically tracks scores and highlights winning combinations. No registration or download is required, so you can start playing instantly.

Tips for Success

To improve your game, practice recognizing patterns and planning a few moves ahead. Start with smaller grids to build confidence before tackling larger ones. In two-player mode, pay attention to your opponent's strategy and block their potential winning lines. Against the AI, try different approaches to learn how the computer reacts. Consistent play will sharpen your tactical thinking over time.
