GAMEPLAY: THINK FAST, MARK FASTER
Each match in Tic Tac Toe IO starts with customizing your challenge—board size ranges from 3x3 to 21x21, and win conditions vary between 3 or 5 marks in a row. Before playing, you also have a chance to select difficulty (Easy, Medium, or Hard) and set a timer for each move. The objective stays classic: place your marks in a straight line before your opponent does on a grid that fits your chosen scale.
Three game modes deliver variety across every play session. Online Mode connects you with real players worldwide in live battles. Two Player Mode allows local competition on one device for quick rival showdowns. Meanwhile, Vs Computer Mode puts you against AI with escalating skill. Each match sharpens logic, timing, and prediction. Larger grids bring longer battles, demanding deeper strategy to outmaneuver your opponent and control space on an ever-expanding digital board.
How to Interact
You just need to click the mouse to set your turn in every mode. If you play with your friend, this command key is still used for each turn, one after another.
