About Four in a Row
Four in a Row is a classic two-player connection game, here pitting you against a sharp computer opponent. You drop your coloured discs into a grid, and they stack from the bottom up. The first player to line up four discs — in a row, a column or a diagonal — wins.
It is easy to learn but surprisingly tactical. Because discs fall to the lowest free slot, every move also shapes the moves available to your opponent. Strong players set up "double threats" the AI cannot block both of, while staying alert to the same trick being used against them. Quick to play, hard to truly master.
