Higher wagered players never going to care about that small cashback rewards they are getting but its good appreciation from the sites to be honest because they don't want to keep all the profits they made into their pocket alone.
To be honest, that's was important too for them.
So, they are a big player and got a nice rake back could help them on gamble but also add more money when they are winning. Instance a deposit bonus sometimes with a stupid wager requitment, I more aggre casino giving a turnback from the platform.
I think this place is not the first place that gives cashbacks to people, there is certainly a lot of places that gives cashbacks and rewards. However roobet is basically known as the best one to do that, it is really built around the fact that they are giving way too much away and constantly doing that non-stop, which makes this website not unique but best at what they do.
You do not have to be unique at what you do, obviously there could be a ton of things roobet does that would exist in other places as well, but at the same time this is a casino in the end so there is limited amount of stuff they can do, the important part is that not only they give cashbacks and many other stuff, they also end up with doing it the best way possible. Is the games best games?
I can argue with that, is the design best design? Maybe, maybe not, is the tech the best one? I am not sure. BUT, I know that rewards are definitely the best.
