No big issues, but their bonuses aren’t that great. FreeSpin casino is ok.  I’ve won there a couple of times. Raging Bull is okay, but they limit cashouts on almost all of their bonuses, which I find annoying. I’ve been in and out of VIP status at both casinos, too.

Which UK casino sites have the best welcome offers?

And they were they first sites I ever played at until i discovered Rival and Betsoft at Drake i think it was, and they sucked me in. Tbh ive only deposited a handfull of times when i did use RD and El R. I used to use Red Dog or El Royale but they switched (actually does anyone have a provider list for them? There are some games ive never seen before).

On one window the slot was totally dead (but had won in days before). Oft wonder why some games run on different platforms – eg Bonanza has about 3 – is it geo reasons? Is it the individual casino or the provider of the game? Uptown Aces – Have had some luck there recently, new casinos not on Gamstop cashed out $600 on a free spin bonus play. There are about 20 games and I like most of them. So you need time to grind these play throughs.

II.Betway – Strong Alternative

If you looking for a reputable list of RTG casinos I would list them for you. But you can pay a visit to Casino Extreme if you REALLY want to play in an RTG casino. You’re better off playing in DAMA N.V. RTG games also have poor paytables and poor payout history. Or the games from the random provider on Red Dog and El Royale LOL.
