I’ve got a couple of questions about the game!

1: What is the best way to not eff up the entire board when you begin a turn, then realize 6 tiles in that it’s not going to work? How do you remember where everything was? Is there a strategy to that?

2: what is the strategy to win? Hold onto the jokers? Use them early? Big runs? A bunch of 3 tile groups?

Any tips?
