Office Pyramid Solitaire

You remove cards by creating pairs of 13 in face value. You can use every card that's not under another one. Pairing suited cards gives double the points! A king (value of 13) is removed just by clicking. Ace is valued at 1. You can deal new cards by clicking the deck on the bottom right. Note that the draw deck is not reused after the last card was dealt on any difficulty.
