Four in a Row
Drop discs and line up four before the computer does.
About Four in a Row
Four in a Row is the classic vertical strategy game: drop discs into a seven-column grid and be the first to line up four. Simple rules, real tactics — beat the computer to earn a place on the leaderboard.
How to play
You play red and go first. Tap a column to drop a disc into the lowest free space. Line up four of your discs horizontally, vertically or diagonally to win — and block the computer's lines. A full board is a draw. Faster wins score higher.
Tips and strategies
- The middle column is part of more lines than any other — take it early.
- Look for moves that create two threats at once; the computer can only block one.
- Check what your disc lets the computer do on top of it before you drop.
Four in a Row strategy guide
Control the centre column. A disc in the middle belongs to the most possible lines, so start there and keep a presence in it.
Build two threats at once. A position where you threaten four in two places can't be stopped with a single disc.
Mind what you set up. Before dropping a disc, check whether it lets the computer play on top of it into a winning spot.
