How to play

Red goes first. Click a column — anywhere in it — to drop your disc into the lowest open slot.

Line up four in a row horizontally, vertically or diagonally to win.
If the board fills up with no line of four, it's a draw.
In Player vs Player you can undo the last move. In Computer mode, undo is disabled.

Hard difficulty looks several moves ahead — it'll punish loose play.
