Neon Abyss

I have grouped all of these cumulative achievements together, because while you'll make progress towards most or all of them while working on everything else, you're unlikely to unlock some or any along the way. There is, thankfully, a pretty easy way to grind out these achievements that doesn't rely on continual RNG for run after run. Basically, play a run, and whenever you come to a floor that has whatever one you need to grind (such as if you find a fishing room, a piano room, a roulette wheel in a shop, etc. Utilize it as much as you can, exhausting all of your money, keys, trades, etc., until you're out. Then, do the Save Reload Exploit mentioned in the roadmap. This will start you back at the beginning of the floor with all your resources back, and the grind spots will be in the same locations. Head back to the rooms/wheels/chests/etc., and repeat. The achievement tracker will keep increasing each time, making it pretty quick to grind these out.

A couple other points to make:
 

• If you're after a specific game room or two, such as just the fishing or piano rooms, you can go to your skill tree in the bar and turn off any other game rooms you may have unlocked, so that only the ones you want will spawn
• The roulette machines mentioned in this achievement specifically are NOT the machines that block your entrance to game rooms on each floor. If you've gambled at all, you'd realize those are slot machines, not roulette wheels. The Roulette wheel is unlocked in the fourth skill tree, and is a bigger wheel with red and yellow sections on it. I highly recommend buying the skill right after it that makes the first play on the wheel free, allowing you to progress this achievement every time you find one without having to risk losing money
