Tic Tac Toe of Different Sizes

Childhood board-game tension returns in Tic Tac Toe of Different Sizes. The usual noughts-and-crosses match branches into rule sets that change the size of the grid and the length of the winning line. Solo rounds pit you against a computer opponent with very tough play. Local matches also support a second person, making head-to-head rounds easy to run with a friend or a parent.

How to play?

Choose borderless mode and place marks until five identical symbols line up, with the grid expanding automatically near the edge. Fixed boards offer 3x3, 4x4, 5x5, 6x6, and 7x7 layouts, each requiring a row that matches the board's target length. Standard 3x3 uses the classic rule set most players know, and larger boards raise the required chain to four, five, six, or seven marks.
