Cards are dealt into 7 columns, with one "base" card beneath the others. You can remove any card from the columns that is either 1 higher or 1 lower than the base card. You may play an Ace on a King, and vice versa. Remove the cards by clicking on them. If there are no cards that can be played on the base card, you can take another card from the pile by clicking on it. The game ends if the pile is empty and there are no more moves.
