Play Alone or With a Friend
Choose 1 player to play against the computer, or 2 players to take turns on the same computer or tablet. Two-player mode is perfect for siblings, friends or a quick family match.
Winning Strategy
- Take the middle column early; it is part of the most lines.
- Block your opponent as soon as they have three in a row.
- Set up two threats at once so they can only block one.
- Think about the row below: don't give your opponent a free spot.
Common Mistakes
The most common mistake is focusing only on your own line and missing your opponent's. Before every move, check every row, column and diagonal for three of their discs. Another mistake is placing a disc that lets your opponent drop into a winning space right above it.
Why It Is a Classic
Four-in-a-row games are quick to learn, fast to play and surprisingly deep. A single game takes only a couple of minutes, but there is always a cleverer move to find. It is a brilliant game for practising thinking ahead, and playing a friend is always fun.
A Short History
Four-in-a-row games have been around for a long time, and the plastic board version with falling discs became a family classic in the 1970s. Since then it has been played by millions of people of every age, from first-time players to serious strategy fans who study the best opening moves. Mathematicians have even studied the game and found that the first player can always win with perfect play.
