How to play Connect 4

Connect 4 (also called Four in a Row or Captain's Mistress) is a two player game on a grid of 7 columns and 6 rows. The rules take a minute to learn. Mastering the strategy takes a lot longer.

The rules in 60 seconds

1

Pick a column

On your turn, drop one token into any of the seven columns. Gravity pulls it to the lowest open slot.

2

Take turns

Players alternate, one token per turn, no skipping. Red always plays red, blue always plays blue.

3

Connect four to win

Line up four of your tokens in a row: across, up and down, or diagonally. First to four wins on the spot.

4

Full board is a draw

If every slot fills and nobody has four in a row, the game ends in a draw. Online, a rematch is one click away.

Who goes first, full columns, five in a row, and every other rule question: the complete rules.

Five ideas that win games

1

Take the centre column

More winning lines run through it than any other. Open there.

2

Build double threats

One threat gets blocked. Two at once cannot be.

3

Watch the diagonals

Most beginner losses are a diagonal nobody noticed.

4

Think in odd and even rows

First player wants threats on odd rows, second on even.

5

Don't hand over the winning square

Check what sits above the slot you are about to fill.

Variant: Pop Out

Pop Out adds one rule that changes everything: on your turn you can drop a disc as usual — or pop one of your own discs out of the bottom row, sliding that whole column down one space. A pop can complete a line anywhere in the shifted column, so no position is ever truly safe. Careful, though: pop carelessly and the discs that slide down can hand your opponent their four — if your pop completes a line for them (and not for you), they win. Pop Out has its own ELO ladder, separate from Classic.

Is Connect 4 solved?

Yes. Connect 4 was solved in 1988, independently by James Dow Allen and Victor Allis. With perfect play from both sides, the first player always wins by starting in the centre column, needing at most 41 moves. Humans don't play perfectly, though, which is what makes ranked games fun.
