Drag cards from the cells, to the columns. Cards are removed from columns when that columns' total value equals 21. The goal is to collect as many stacks of 21 as possible in the time allotted. The most recently placed card in a column can be moved to another column at a cost of 5 points per card moved. Each time a card is moved from a clel, the remaining two cards in the remaining cells rotate to the next lowest cell.
