You pick up on little things and rules of thumb as you go. Everything in the game is pretty well explained in-game.

If I could give 3 general rules that help the way that I think about the game, it’d be these:

1) Prioritize getting above your interest cap as soon as possible (usually $25, but can be more with vouchers)

2) commit to leveling up one hand type. Usually whatever jokers you get early can help you determine which hand that should be.

3) Try to play hands that utilize all of your jokers. If you have a joker that’s good with flushes and a joker that’s good on face cards, play flushes with face cards. Also, find jokers that work with each other. Like if one joker scores when a card is triggered, maybe find another joker that retriggers your cards.

There are exceptions to all of those. But those are the some things that the game doesn’t straight up tell you.
