Play Lounge's Ultimate Tic-Tac-Toe expands the classic game: win a round and the board grows — 3×3, then 4×4, then 5×5 — with the goal still three in a row each round. The growing grid opens far more lines and threats than standard Tic-Tac-Toe, rewarding players who plan ahead and create multiple simultaneous threats instead of chasing a single line.

Instead of one 3×3 grid, the board expands each round (3×3 → 4×4 → 5×5). The bigger boards create many more lines and threats, so games are deeper and rarely end in a quick draw.
Pick the game, create a room, and send the invite link to the second player. They open it, join automatically, and you take turns each round.
Yes — free with no account and no download, and it installs as an app on any device.
