3Dice are a fantastic casino and in many ways you'd be hard pressed to find a better place to play. And I don't just mean as a US player who doesn't have many choices, because in many regards 3Dice are pretty much class leaders.
I really got into 3Dice a few months ago and TBH I have no 'real' complaints about them whatsoever.
Their customer service is fast, friendly and responsive.
Their payout times to Neteller are superb, almost always within 12 hours and quite often within 3 hours or less, even over weekends and holidays (on one occasion it was inside of 30 minutes IIRC).
Their slots are unique, and the payouts seem to be fair, albeit a bit on the low side RTP-wise with around 95% T-RTP, plus they don't list the RTPs on slot-by-slot basis but they do report actual payouts in two main categories over a variety of timeframes, which immediately makes them a billion times better than anything Microgaming can be bothered to do.
I did have a couple of issues with them in the end however, which is why I stopped playing there.
1) Their VIP system is pretty opaque. I was working my way up the ranks reasonably well but it seemed that the only way to progress was for me to wager more in one 'qualifying period' than I had done in the previous qualifying period, it almost felt like I was compelled to deposit even when I didn't really want to, just to maintain my status, let alone get demoted a rank.
After a really bad run on one of their slots (Fortune Falls) which I got far too involved with (entirely my own fault), I tried some stupid roulette gambles with my rainy day funds, busted out on them as well, and then in my 'cooling off' period (I didn't really feel like playing or depositing there), just watched my VIP status drop down every ten days because I wasn't depositing.
I had used and replenished my rainy day funds once before, but didn't feel inclined to do so again.
2) Slot design is a bit off IMO, they do list the variance of their slots based on their 'own scale' which is absolutely to be applauded. However, with a slot like Fortune Falls, a chunk of the RTP is tied up in the 5-scatters bonus, despite it being listed as a medium variance slot, if the player doesn't hit that round it really can be quite a tawdry experience to play - death by a thousand cuts.
Now again, I cannot fault 3Dice in any way here in that I asked them specifically what the odds of hitting the 5-scatters bonus round was, and their CS got back to me with the exact numbers, very impressive transparency - but my annoyance at the design of the slot was not mitigated
3) I reported the misspelling of 'LUCKY NUGGET' in their video poker games (in fact, they manage to spell it wrong in two different ways), and the CS person I communicated this to said they'd fix it. They never did, it's still misspelt. This sort of stuff looks rubbish and annoys me.
4) They also told me they'd split out the T-RTP of their slots down to a game-by-game basis, this hadn't happened either when I uninstalled.
OVERALL - 3Dice are a fantastic casino with some truly original games and even though I've made the choice not to play there any more, I would still suggest others give them a fair crack of the whip. I am an incredibly fussy customer (see point 3 above
) - and none of my problems with 3Dice are what I would consider to be deal-breakers, I just decided that on balance I didn't want to play there any more.
If they fix points (1) and (4) above, I'll almost certainly go back to playing with them again. (3) would be nice as well, seriously dudes, just open a dictionary.
