Play connect four online for free on Classic Play Games. The classic two-player connection game — drop colored discs into the grid and be the first to connect four in a row horizontally, vertically, or diagonally. Challenge the AI or play against a friend, no account or download needed.
Connect Four is played on a 7-column by 6-row vertical grid. On your turn you choose a column and drop one of your coloured discs into it — the disc falls to the lowest empty slot in that column. The first player to line up four of their own discs in a row (horizontally, vertically, or diagonally) wins.
If the grid fills with no winning line, the game is a draw. Strong play is mostly about creating multiple threats your opponent can't block at once and controlling the centre column, where the most winning lines pass through.
Easier AI levels miss subtle double-threats and reactive blocks; stronger ones look several moves ahead and refuse to let four-in-a-row setups develop. Pick your level and step it up as you improve.
Local two-player mode lets you share one device — pick a column, drop a disc, pass to your opponent.
