AFAIK house edge of the dice game at roobet is 2%, if I'm correct about it then I cant say that it is pretty low like what you say.
Most other dice sites has 1% house edge which is the standard house edge of dice in this gambling industry IMO, so I wonder how can you say it as pretty low.
No personal offenses to roobet, just wondering which other sites you use to compare the house edge. Freebitco.in?
I never said it is the lowest out there, but I mentioned that it was low. 2% is still low though not as low as other sites. 2% house edge plus their roo-rewards make them an appealing choice for gamblers interested in reward systems basically.
Why do you need to move on to another site when you are already playing at a trusted site, stake.com. Even if you are able to find a better site for high rollers, there won't be much difference. Also the new sites can offer more better reward programs but they may scam you in the end. Better to stick with stake.com as you know that they won't cheat you.
He was simply inquiring about casinos with great reward systems and Stake is not the only option in this case as other posters including me pointed out above.
