Did you mean VIP Clubs/RooWard, they only have that's. If you mean VIP Clubs, its a service from Roobet for a qualified user maybe with a big wagers has been spending into the platform to get a personal manager support roobet. So, when they have a problem and other things they will get priority support from roobet kinda different with normal player when they contacting support need to wait first.
If you mean "RooWard" how they work, you will get a cashback certainly % from the amount money you lose on the platform. The maximum level reward is "10", just click rooward if you want to see how many left you need to wager to the next level. You can claim with daily, weekend and monthly as long the claim button show up that's mean you can claim the reward.
I believe the % of rooward around 3-5%, I lose some money around 100$ they give me in the range 1-2$ for each claim daily, weekend and monthly. Total rakeback from my claim around 4-6$, so definilty they give a % for toward around 5%.
the vip club. there is not any information on what to expect from it, what wagered amount is needed, etc. i am wondering if i should change from rake and butsir to this site but i have no way to compare the benefits
Ryza is right about the returns though, you get like 5% and even more stuff and considering all the promotions and other stuff with it, you basically drop the house edge down under 1% with all you win (if you are lucky for some of them) and that is what matters, dropping the house edge while making money from other promotional stuff, it at least guarantees a smaller loss chance.
