Learn how to play Connect Four and the tactics that win, then take on the computer in the board above.
Be the first to line up four of your discs in a row, horizontally, vertically or diagonally.
The middle column is part of the most possible winning lines, so playing there first is a strong advantage.
Aim to create two ways to win at once. Your opponent can only block one, so the other wins the game.
Because discs stack, the row a threat sits on matters. Think about which squares will be reachable after the columns fill, not just the current move.
Never ignore an opponent's open three that can become four on the next move. Block it unless you have an immediate win of your own.
Players take turns dropping discs into seven columns, and each disc falls to the lowest empty slot. The first player to line up four of their discs horizontally, vertically or diagonally wins.
Play the centre column. It belongs to the most potential four-in-a-row lines, and with perfect play the first player who starts in the centre can force a win.
Create a double threat, meaning two separate ways to connect four on the same turn, so your opponent cannot block both. Always take the centre early and block any open three-in-a-row your opponent makes.
Yes. If all forty-two slots fill up without either player connecting four in a line, the game is a draw. Good play, however, usually forces a win or loss well before the board fills.
