Pyramid Solitaire 3D のアプリ分析 7月28日

This is the classic game of pyramid solitaire. Pick pairs of exposed cards, that add up to the number 13, and place them on the discard pile to the right. The king's value is 13 so it can be discarded on its own. The game is complete when all the cards have been placed on the discard pile, so that there are none remaining anywhere else.
