Can you tell me:
* What kind of Joker game are you talking about? Is it a game you learned from friends or family? Is it a local variation on a more common game?
* What is the goal of the game? Is it about getting rid of all your cards, making the highest score, or something else entirely?
* How many players are involved?
Once I have this information, I can give you the rules and help you learn how to play!
