Play Cowboy Gin Rummy at Solitaire Paradise
Create sets of 3 or 4 cards consisting of either all the same numbers or a sequence in the same suit. All cards that are not in combination count towards your deadwood total. If your deadwood total is less than 10 you can "knock" and see who the winner of the hand is. Beware though, if you try to hold out too long your opponent may knock before you and win.
Try to beat the cowboys you are up against.
