Connect Four

Rules

1. Red starts, then players alternate turns.
2. Select any non-full column to drop a disc to its lowest open square.
3. Make a horizontal, vertical, or diagonal line of four discs to win.
4. If all 42 squares are filled without a line of four, the round is a draw.

Controls

Select any square in a column to drop your disc into that column. This version is for two players sharing one device.

A brief history

Four-in-a-row games existed before the well-known retail version. Milton Bradley introduced Connect Four in 1974, and its vertical board turned a simple alignment game into a compact contest of threats, blocks, and forced moves.
