On the tableau, there are four space for building cards (foundation). You place the cards on each foundation in ascending sequence from A to K, each foundation being the same color. Cards on the tableau can be piled in a descending sequence from K to A. At this time, cards should be piled in alternating colors, i.e. black (spade/club) and red (heart/diamond). Only K can be placed on a vacant column. Cards of other numbers cannot be placed there.
