What is Connect Four?
Connect Four is a two-player game on a vertical 7×6 grid. Players take turns dropping discs into columns; a disc falls to the lowest free slot, and the first to line up four discs in any direction wins.
How to play
- You play red. Tap a column to drop your disc — it falls to the lowest free slot.
- Line up four of your discs in a row — horizontal, vertical, or diagonal — to win.
- The computer uses an alpha-beta search; raise the difficulty to make it look further ahead.
