Welcome to Metagrid β the evolution of Tic-Tac-Toe. Metagrid (also known as Ultimate Tic-Tac-Toe) takes the classic game you know and adds a layer of strategic depth that changes everything. How it Works: The game is played on a large 3x3 grid, where each cell contains a smaller 3x3 board. The Golden Rule: The cell you play in standardizes which board your opponent must play in next. Win a small board to claim that cell on the main grid. Win three small boards in a row to win the game! Features: Single Player: Challenge our "CPU" AI and sharpen your skills. Local Multiplayer: Pass-and-play with a friend on the same device. Stunning Design: A clean, minimalist interface with fluid animations and a "frosted glass" aesthetic. Highlight System: Intelligent highlighting shows you exactly where valid moves can be made, making the complex rules intuitive to learn. Forget draws. Forget boredom. Enter the Metagrid.
