Agreed - slotastic and slottocash (i believe they are the same company) have been good.
Don't think that's true. Some quick searching says that slotocash = deckmedia, slotastic = jackpot capital.
In my own experience, there's no such thing as a perfect RTG casino now.
Slotocash group has been decent (slotocash, fairgo, uptown aces, think they might also have a rival and WGS casino), but live support is really slow and when i won a few months ago they (fairgo) kept screwing me over on the bitcoin exchange rate - once as bad as 10% off. There's no reason that should happen, the player shouldn't have to check every withdrawal to make sure they didn't get screwed, and many probably don't. They did correct the biggest one after i went through the pain of talking to a customer support agent for half an hour who kept telling me that they're not responsible for price fluctuations, despite the error having nothing to do with price fluctuations. They do have good bonuses though.
Haven't played slotastic directly recently, but played lucky club (think it's the same owner?) with a few hundred dollar win and they're sure taking their time on the cashout. Been almost two weeks since I submitted verification documents. Support is very slow, email support didn't even respond to me.
Casinomax group has quick support, but pretty bad bonuses and the jackpots are all pretty low right now due to low player volume. Also have a weird phone verification step that no one else does (?).
Casino Extreme has quick payouts. Bonuses aren't the best but better than casinomax. My own bad results + terrible video poker payout tables make me worried about what the slot payouts are set at though (Real time gaming has configurable RTP settings, which I hate personally since I never know if I'm just unlucky or getting screwed by unfair games).
RTG or not, I don't think I can name a US facing casino that I'm 100% happy with now, it's always a bunch of tradeoffs.
Out of curiosity, does planet 7 really have a 50,000 jackpot on paydirt right now? Don't feel like making an account to check, but that's crazy if true - it's like a 1 in a million chance of getting that high. Guessing the display is probably wrong. Though it doesn't matter anyway unless they use a decent RTP setting and pay out winners in a timely manner, sounds like some people have had problems there.
