The subname for this cache is " Casino Night ". At ground zero you will find a special deck of cards. There are a set of instructions with the cards. I am making this a difficulty 3, just because it may take you a few minutes before you have that "ah ha" moment. Plus you will need a calculator and you will need to know your poker hands. ( 3 of a kind, flush, full house etc..) If you do not, then I suggest printing out a list of the poker hands and what they look like before leaving the house. Once you have figured out this field puzzle, you will have the combination to the lock on the ammo box full of swag and the logbook.
Have fun and if you enjoyed this cache, I do appreciate when a favorite point is added letting other cachers know this was a unique and fun cache to visit.
