Game
Join 4
Drop, stack, win — Connect 4 done right.
Join 4 is the vertical four-in-a-row classic: drop your discs into the grid and stack a line of four before your opponent does, going across, up, or diagonally. It looks simple, but the first player can force a win with perfect play, so every drop matters. Play free against sharp bots or online with friends.
