Tall Tower Pyramid Solitaire
Tall Tower is a modified version of Pyramid Solitaire. It's a little different from Pyramid in that there is no stock pile to deal new cards from. It's a pretty difficult game, and it's rare that you can win, but the goal is to try and get as high a score as you can in any given game.
Like in Pyramid, you're trying to match up cards that have a total value of 13. You can just click a King to remove it from play because it has a value of 13. The pairs of cards you can make are Ace and Queen, 2 and Jack, 3 and 10, 4 and 9, 5 and 8, and 6 and 7. To win the game you have to remove all the cards from play. The game ends when you no longer have any matches left.
