Monaco Solitaire Card Game. The aim of the game is to remove all cards. A pair of cards (or an Ace) will be removed, if they add to 15 (Ace, K+2, Q+3, J+4, 10+5, 9+6 or 8+7). The cards of that pair must be from adjacent places (vertically, horizontally or diagonally).
The remaining cards will be shifted in direction of the top left card and empty spaces will be filled with news cards. If no more cards are to deal and all cards are removed then you have won. Good luck!
