@Don Pedro Thanks for the reminder to brush up on my maths, so what is this commission you're talking about, is it your term for the house edge itself? Because I thought commission is only charged on games like Baccarat.
Well, I have to say that I know in poker it works like that, and I understand that in casino games it will work like that too because if not, the casino would be at a loss with respect to the players who increase the %.
In general, I am referring to the House Edge, what the House makes.
If it is 2%, out of every 100 dollars and in the very long term you will get 98 dollars back. The long term is important because in the short term we all know that you get jackpots and other prizes.
So, what you get back has to be calculated on 2%, not on 100%, which is what you thought here:
Rakeback for my level now (Expert) is 7.5%, which is way more than the below 2% house edge of roulette. I never truly calculated though!
It gives you back 7.5% of the 2% it takes, which means that instead of keeping 2% of every 100 dollars, it keeps 1.85%. In the case of Saint-loup, which is 10%, it keeps 1.8%.
I don't know how livecasino.io works from the inside, but for me it makes more sense that you get a refund on HE, than on the total, which would be a ruin for the casino.
I don't know if anyone from the casino or who knows how casinos in general work in terms of cashback can confirm, deny or qualify this.
