Tic Tac Toe IO is a new take on the classic game of tic-tac-toe that lets you play against people from all over the world in a tactical way. You need to line up three identical symbols horizontally, vertically, or diagonally to win. The game has a simple look and is straightforward to play, but it requires smart math.
Players take turns picking boxes on a 3x3 board and marking them with "X" or "O" symbols. The first person to make a row of three symbols in a row in any direction wins.
Online mode: Match and compete with real players from all over the world.
2-player mode: Play directly with friends on the same device.
Computer mode: Compete against the computer with many different levels of difficulty, suitable for both beginners and experts.
Use your mouse to click on the box you want to mark.
