Four in a Row

Take turns dropping discs into the seven columns. First to line up four in a row (across, down or diagonally) wins. The Hard computer searches a dozen moves ahead.

Four in a Row is a quick strategy game for two players. Take turns dropping coloured discs into a grid of seven columns and six rows. The first player to line up four of their discs in a row, column or diagonal wins.

It is simple to learn but has real depth: the Hard computer looks a dozen moves ahead.

How to play Four in a Row

Red goes first. Tap a column (or press 1 to 7) to drop a disc. It falls to the lowest empty space.
Take turns. Try to line up four of your discs across, down or diagonally.
Block your opponent whenever they have three in a line with a free space.
If the grid fills up with no four in a row, the game is a draw.

Tips

The middle column is the most valuable: play there early.
Look for moves that create two threats at once. Your opponent can only block one.
Be careful about filling a column under your opponent's threat.

Questions

Who goes first?

Against the computer you choose. Online, the host chooses or it is random.

Can the first player always win?

With perfect play the first player can force a win, but it is very hard for a human to do.
