Description
Instructions: Use your mouse to play this game.
Tic Tac Toe HTML5 brings noughts and crosses to the browser. Besides the familiar 3x3 board it adds two larger grids, 5x5 and 7x7, and on those a line of three is no longer enough, because you need four marks in a row.
The bigger boards change the game quite a bit, since there is far more room to set up threats and far more to defend. You can click your marks onto the grid at a desk or tap them in on a smartphone. More thinking games are in Strategy.
Rules on each board size
On the classic board the two sides take turns placing X and O, and whoever completes three in a line across, down or diagonally wins. The 5x5 and 7x7 boards follow the same idea, except the winning line is four marks long. Like any tic tac toe, a grid that fills up without a winner ends in a draw.
Playing it well
- On 3x3 the center square takes part in the most lines, so it makes a strong opening.
- Before you work on your own line, see whether the other side is one mark away from theirs.
- On the 5x5 and 7x7 boards, try to build two possible lines at once so a single block cannot stop both.
