royal flush - ace, king, queen, jack, 10,
straight flush - has to be in the same suit, the cards must go in order. Like from 8, 7, 6, 5, 4
flush - 5 cards in the same suit
full house - Same 3 cards of one kind, plus 2 cards that are the same of one kind. Like 3, 3, 3, 2, 2
I know I'm missing some. Straight, sometimes I get it's rules mixed up but it seems to be mixed cards of different suits in order.
