How to play Connect 4
- 1
The board is a grid standing on end — 7 columns wide and 6 rows tall — and the goal is to be the first to connect four of your own discs in a row.
- 2
Red drops first, then Yellow, alternating one disc per turn.
- 3
Click or tap any column to drop your disc into it — gravity pulls it straight down to the lowest empty slot in that column, so you can't choose the exact row.
- 4
Connect four of your discs in a row to win — horizontally across, vertically up a column, or diagonally in either direction. The board highlights the winning line the moment it happens.
- 5
Watch the whole board, not just your own discs — you need to notice and block your opponent's three-in-a-row before they can complete it.
- 6
If all 42 slots fill up and nobody has connected four, the game ends in a draw.
- 7

Tips & strategy
Grab the centre column when you can — it takes part in the most winning lines.
Always scan for the opponent's three-in-a-row and block it before it becomes four.
Build a 'double threat' — two ways to win at once — so a single block can't save them.
