Play Four in a Row online with a friend
Four in a Row is a two-player strategy game about building a line while stopping your opponent from doing the same. Discs fall down a column, so you cannot place one anywhere you like. I like how a simple turn can create a threat several moves later, especially when both players are watching the centre.

How to play Four in a Row
Goal: Be the first to line up four of your discs in a row: across, up and down, or on a diagonal.
- Take turns dropping one disc into a column. It falls to the lowest free spot.
- Block your opponent’s lines while you build your own.
- Ring discs and dot discs have different shapes, so colour is never the only clue.
- Against the computer, 💡 Hint suggests a good move and says why.
