How to play Connect Four

- Block your opponent’s rows of three while you build your own.
Common questions
How do I drop a disc?
Click or tap the column you want — your disc drops to the lowest empty slot in that column.
Is there a computer opponent?
Yes, the game plays against you using a Minimax strategy, so it offers a real but fair challenge.
