Four in a Row: drop discs, line up four
Line up four discs before the computer — or a friend — does.
Drop discs into a seven-column grid. Get four of your color in a line — across, up, or diagonally — before your opponent does. Play the computer at three difficulty levels or pass the device to a friend.
How to play Four in a Row
- Tap a column to drop your yellow disc to the lowest open space.
- Players alternate turns.
- Line up four in a row horizontally, vertically or diagonally to win.
- If the board fills with no line, it's a draw.
Tips and strategy
- Claim the center column — it's part of more possible lines than any other.
- Watch for threats your opponent builds two moves ahead.
- Create two threats at once; your opponent can only block one.
- Think about which row each threat sits on — odd and even rows matter late in the game.
About the game
Vertical four-in-a-row games have been played for decades, and the standard 7×6 board has been studied deeply by mathematicians. Our computer opponent looks several moves ahead and gets sharper on Hard.
