Tic Tac Toe 1-4 Player

Tic Tac Toe 1-4 Player starts in one click — a Puzzle game with nothing to install and no account to make. Designed around touch input, and comfortable on a small screen. Catalogued as 1 player, 2 player, 2 player games, 2d, mind.

It is drawn for a tall screen, so it fills a phone held upright rather than a wide monitor. Free to play in the browser, with no install step between you and the first round.
