Pairs of cards can be removed if their values total 13. In this game, Jacks value at 11, Queens at 12, and Kings at 13. Thus, kings can be removed immediately. Cards must not be covered. Thus when an Ace rests on a Queen, that Queen can not be removed. When going through the stock, the cards are drawn one at a time with no redeal. To win, get all the cards from the pyramid to the foundation.
To play, drag a card over top another card and if they add to 13 they will be discarded automatically.
