Four in a Row

How to play Four in a Row

1. Tap a column to drop a disc: it falls to the lowest free spot.
2. Line up four of your discs in a row, a column or a diagonal to win.
3. You play red against the computer, or choose 2 players for a game with a friend.
4. If the board fills up with no line of four, the game is a draw.

Tips

• Play in the middle column: it is part of the most possible lines.
• Watch the diagonals: they are the easiest threats to miss.
• Build two threats on top of each other: the opponent cannot block both.
• Before dropping a disc, check whether it lets your opponent play just above it.
• On Easy and Medium, and with two players, Undo takes back your last move along with the computer's answer. On Hard, every move counts.

About Four in a Row

Four in a Row is a classic connection game played on a vertical board of 7 columns and 6 rows. Gravity is the twist: you can only play on top of what is already there.

The computer uses minimax with alpha-beta pruning: on Medium it looks 3 moves ahead, on Hard 5 moves, and it values open lines and the center column.
