Tic Tac Toe HTML5
Why We Picked Tic Tac Toe HTML5
Three board sizes, and only the smallest one is the game you remember from the back of a notebook: the 5x5 and 7x7 layouts ask for four marks in a row instead of three, which turns a solved game into something you can actually lose. On the small grid, perfect play draws every time, so the larger boards carry the interest. With 209 plays it is a footnote in the category, but the variant idea is better than most of the tic-tac-toe pages here.
How to Play
Three things decide whether a run here goes well:
- Switch between the 3x3 board and the larger grids, then claim one square per turn.
- On the small board, line up three marks; on 5x5 and 7x7, four in a row wins.
- Always block a two-in-a-row threat first, even when extending your own line looks more tempting.
Editor’s Note
A two-minute time filler, and the bigger boards are the only reason to open it twice. The page is bare of explanation, so pick a size and learn the rules from the grid.
