How to play Connect Four

Connect Four is a two-player game on a grid seven columns wide and six rows high. Players take turns dropping a disc into a column, where it falls to the lowest empty space. The first to line up four discs in a row, across, down or diagonally, wins.

Red always drops first. If the grid fills up with no line of four, the game is a draw. Play the computer on Easy, Medium or Hard, or choose 2 players to take turns on one device.

Connect Four questions

What is the best first move in Connect Four?

The centre column. It takes part in more possible lines of four than any other column.

Can I play Connect Four with two players?

Yes. Set Opponent to 2 players and take turns on the same device.

How good is the computer on Hard?

It searches many moves ahead and takes any forced win it finds, so it punishes mistakes quickly. Easy and Medium are far more forgiving.
