True, a few have looked, but apart from Trada i have not really tested either of those: i did sign up to Trada and Slotsmillion recently, and also after reading a lot of good things here and elsewhere: but, i have not cashed out there yet, and don't know enough about their loyalty scheme to advise you to go check them out..
But as Jazzy stated, if you like MG then 32Red should be a perfect fit: they have excellent loyalty rewards, especially if you get into Club Rouge - if you don't. or if that takes too long to achieve, then their Management and/or Player Experience or VIP team, will take care of you if you show loyalty.
Nowhere else have i been treated better consistently over the years, save for 3Dice maybe, but despite their (3Dice's) awesomeness, they don't even come close to the pampering i received from 32Red..and that says a lot if you know how generous 3Dice is
Both places are great, and reward player loyalty much more then elsewhere, as far as i know, and i played at
a lot of places!
Don't know about the CAD, but i know they do pay without hassle.
If you want the (nowadays) more common multisoftware platform, then i'd say don't expect any loyalty rewards..
I have no good experiences there, at least not consistent -
fast payouts yes, and plenty of regular promo's, such as match-ups, races, cashback and whatnot, but nothing compared to the 2 Casino's i mentioned above.
The accredited Casino's i play at (or have played at) extensively, are V&J, MrGreen,
Unibet & Maria,
Rizk and Guts, and i also have dabbled in BetAt and VS, and since recently as stated Slotsmillion and Trada - fast pay-outs and such at most of these, plenty of software at most of these but nothing worthwhile in terms of consistent player rewards - although i perhaps jumped the gun regarding BetAt and VS, as i didn't really play there enough to build up loyalty, but that was because i didn't like their bonus systems..
On that note it's worth to mention that although i only did a few deposits in Slotsmillion so far, they were nice enough to chuck in a 20 Euro freebie, without asking for it, so perhaps they will prove to be great as well..
Casinoluck is worth a special mention: i think they were the best multiplatform for a long time, in terms of consistent rewards/loyalty scheme, but since the transition to the new platform recently, i haven't been compelled to play there anymore. which is a damn shame!
If you read around, there are loads of regulars that were/are really happy with BetAt and VS, they've won numerous awards already, and also were quite involved, so my limited play and experience there may not be enough to give a fair picture. But my play @ MrGreen, V&J, Uni/Maria, and Rizk and Guts definitely was!
Mind you, these are top rated Casino's and are worth your dough, but if you're looking for Loyalty rewards...you may be disappointed..
And again, i say consistently -which to me is a very important point: i don't care for loads of juicy freebies and whatnot in the start, and then nothing after years of play, unless you have to ask or 'threaten' to stop playing - that to me are hook, line and sinker tactics, or regressive rewards, and i utterly despise that
So, i hope that helps a bit..
