Thanks. I was hoping to build up a bigger coin stash before trying those rooms. Currently, I'm just trying to get apparel, so I've just been playing Chelsea, with all SE clothing, to get the extra chests.
I have been thinking about what would maximize the rate of apparel I get, as I understand from the Forum that the higher rooms usually drop a higher percentage of Gold/Platinum than Chelsea, and more apparel per chest.
However, I'm also concerned that I wouldn't win nearly as often as I do in Chelsea in the higher rooms, and I've heard it takes a lot longer to find a partner, so I'd probably be playing fewer games during the sponsor period. Additionally, in a good month I win about 66% of my games in Chelsea. If that drops below 56% in a higher room, then I'll be going backwards in coins.
