How to play Connect Four
Take turns dropping coloured discs into the seven columns. A disc falls to the lowest free slot in that column. The first player to connect four of their discs in a row — horizontally, vertically or diagonally — wins. If the board fills up with no four-in-a-row, it's a draw.
Difficulty
- Easy — the computer often plays casually; great for a confident win.
- Medium — the computer looks a few moves ahead and blocks your threats.
- Hard — the computer searches six moves deep with a strong evaluation. You'll need a real plan.
Tips
- Play toward the centre column — it's part of the most winning lines.
- Watch for double threats: set up two ways to win at once so a single block can't stop you.
- Always check whether the computer is one move from four — and block it.
