Two players, one keyboard, and a very small screen between you. That is one classic shape of browser multiplayer. Another is a quick online match against whoever happens to be around. Either way, a session is a run of short rounds where the result depends on another person's decisions as much as yours. Trash talk is optional but common, and so is the rematch.
Tic Tac Toe Blackboard turns a laptop or tablet into a two-person arcade with no setup. It is free, needs no download or login, and rounds are short. The unpredictability of a human opponent keeps even simple games interesting far longer than they would be alone.
Suits pairs and small groups, from children playing with a sibling to adults at a kitchen table. Solo players who want online opponents also fit. It works best on a laptop or tablet.
