In the "13 is a winner" solitaire you need to disassemble the layout of cards, removing 2 face-up ones, with an additional condition: the sum of the card values must be 13. You can also take a card from the auxiliary deck, which is located at the bottom of the screen. Tens give 10 points, Jacks - 11, Queens - 12, Kings 13 (the only card that is removed alone, kings do not need to find a pair) and Aces - 1 point.
