I enjoyed this alot! Really well made and I love the jazzfunk classics lol. There's a huge amount of depth here for a jam game and yet despite that, I was able to pick up what's happening pretty easily. One I saw was that once you stacked chips on a slot, which it's great you accounted for, there didn't seem to be a way to unstack them. Also felt like the economy was hard to manage, with there rarely being enough cash to buy upgrades. I wonder if you could play with upgrades that change the roulette probabilities themselves, rather than just the table? Could be interesting.
I hope this gets expanded, there's a lot here to keep developing.
