In 3X3 Mode, you must get three Xs or Os in a row to win (Horizontally, vertically or diagonally). Simply click or tap on the square of your choice to add your mark to the grid. For players with some Tic Tac Toe experience, choosing ‘Hard’ is the best option.
For absolute beginner players, we recommend the ‘Easy’ setting as the computer opponent is quite weak. Remember, X always goes first, and O goes second. Once the game loads, tap or click to choose to play on a 3X3 or 5X5 grid, select your difficulty level (Easy or Hard), and whether you want to play as the Red X or Blue O.
How to Play: Note for players on mobile phone / tablet: To play the game with full screen, you have to turn your device horizontally. This fast-paced, mouse-clicking, observation, skill and strategy-based game requires logic, high concentration, a competitive edge, accurate screen or keyboard tapping skills, and an element of luck (Sometimes, in evenly-matched games, you must stay solid and hope for your opponent to make a mistake). In this fun online version called X vs O, you can choose to play on a standard 3X3 grid, or on an expanded 5X5 grid where you must place 4 Xs or Os in a row to win! Good old-school tic-tac-toe combined with fun animation: Play Tic Tac Toe against the computer on your desktop, laptop, tablet, or mobile device! Also called ‘Xs and Os’ or ‘Naughts & Crosses’, Tic Tac Toe is a classic, one-on-one, pen-and-paper-style game for little kids, teens & grownups where you race to place three X or O marks in a horizontal, vertical, or diagonal row on a grid (or board).
