So i have tons and tons of these cards called Jack of Spades- Delux, or other names, what am i suppose to do with them ? Venders seem to sell them, and you can pickpocket them off people, but i dont see use for them ?

I think they are for the game called "Caravan". I tried to play and was told I need 30 cards, which I assume is what we're talking about.

Yea but how do i use them with the deck that was given to me ? I still dont know how to play caravan lol.. Anytime i discard a card i cant do anything else but discard a card or end the game and lose.. lol
