Infomation:
Monte Carlo is a pair matching solitaire and uses only one standard deck of 52 playing cards. At the beginning of the game, 25 cards are dealt in a five by five grid. The remaining cards forms a face-down Stock pile on the side.

Your goal is to clear Monte Carlo of cards by selecting 2 adjacent cards (horizontally, vertically or diagonally).
In the Doubles (x2) mode it should be a same pair (two Kings, to Sixes).
In the 13 mode they should add up to 13. Aces count as 1, Jacks - 11, Queens - 12. Kings count as 13 and can be removed on their own. All other cards count at their face value.
