Make 10 pyramid card game

The aim of the game is to clear all the cards from the table by making pairs which total 10. Only cards which are completely uncovered can be paired together. Once no more pairs can be made, a card can be taken from the draw pile. If no pairs can be found with this card, another card can be drawn. Continue this until you have removed as many cards as you can from the table. Any cards left over, you add together the total number of points and that is your score for the game.
