The hand with the highest total wins as long as it doesn't exceed 21; a hand with a higher total than 21 is said to bust or too many. Cards 2 through 10 are worth their face value, and face cards (jack, queen, king) are all worth 10. An ace's value is 11 unless this would cause the player to bust, in which case it is worth 1.
Have fun playing Spy Solitaire and try to beat all the levels. Your goal is to get the 2 identical cards together till getting the table empty. If your don't find the pair you can ask for a hint 3 times.
