Logic behind the game

Question

Ok, I honestly don't know how this works. How would I evaluate hands, Vulpes?
When I click deal and cards displayed then if anything above pair 10's would give player money otherwise it goes back to house / w.e you call him.
As you can see in my Game class I got PayOutMoney method that contains all the hands and such, but now how would I connect that methods with the cards that will be displayed?
