The object of the game is to be the first to connect your four colored discs in a row horizontally, vertically or diagonally on the playing field.
Players take turns to move. The player who moves first throws one of his colored discs into any of the columns on the playing field.
The disk falls straight down and occupies the lowest available space in the column.
After the disk is placed, the turn passes to another player who does the same thing, dropping a disk into any column.
The game continues until one player lines up a row of four discs of his color vertically, horizontally, or diagonally.
