Wolfy Casino started their own thread last year, you can check what others have said
here 
WOLFY CASINO looks pretty good. KYC verification for cryptocurrency players is not required, which is a very big plus these days. Haven't seen any negative feedback so everything looks really positive. However, there is definitely a lack of activity and marketing on Bitcointalk.
seems that this casino has no budget for promotional activities. also, the OP is not active in this forum. but looking at their site, they have some bonuses going on. maybe, they got their players outside this forum and they are sustaining their business without actively promoting this here.
