How to play four in a row

Red and Yellow take turns. On your turn, choose a column that still has room and drop one disc into it: the disc falls to the lowest empty space. Discs never move again. Four of your discs in a straight line — across, up and down or on a diagonal — wins at once, and a longer line wins too. If all 42 spaces fill up without a line, the game is a draw.
