Pyramid⁞ 與 Classic Pyramid Solitaire 使用情況與統計

Pyramid solitaire is a well-known solitaire game. The goal in this game is to remove all cards on the pyramid by pairing the cards which give a sum of 13 points regardless of their suits. You can click to remove any pair of cards on the pyramid or the discard pile that gives the sum of 13, for example A and Q, 10 and 3, while a K can be removed by itself. When no moves are available, click the stock pile and get a new card. Count your steps wisely, clear all cards and win the game!
