About Four

Four is a free daily Connect Four puzzle from Source of Truths. Every position is a real, reachable board with you to move and a forced win already there, and your job is to find the one column that keeps it. Tap a column and the disc drops, so there is nothing to learn before you play.

Each board has exactly one winning column, checked by two independent solvers, and the win takes exactly the stated number of moves against the stiffest defence, never fewer. What makes it bite is that a wrong drop is not refused. The engine is perfect and it plays the game out, so a careless move costs the win for good and leaves you fighting for a draw.

A new position drops every day at midnight Eastern, and Sundays step up to a win in five. No app, no signup, play free in your browser, keep a streak, and race the daily leaderboard. More dailies: Mate, our daily chess endgame, Etch, our daily nonogram, and Suds, our daily sudoku.
