Try playing mexican sweat. It's poker with craziness involved
I like cribbage and gin rummy.
Uno.
,BS! It's my favorite game.
There is always gold fish :)
Slapjack is the only one I can think of, the other being Uno, and the rest requiring more than two players... Another fun thing to do is make a card tower!
Spit or Speed. We used to have tournaments with my cousins. Two of my cousins still have a Spit tournament every year. With bragging rights for the whole year. We are a competitive bunch.
Well... Depends on the 2 people... Strip Poker is the best, when applicable lol
Cribbage.
