How to play Linefall

1

Drop a disc

Pick a column and let go. Your red disc falls to the lowest open slot. On a phone, tap a column, or drag across the board to aim and lift to drop.

2

Line up four

Get four of your discs in a row: across, up and down, or on a diagonal. The computer is trying to do the same with yellow.

3

Outthink the AI

Casual looks four moves ahead, Sharp six, and Grandmaster seven. Center columns build the most lines, so the AI fights hard for them.
