Holkapolka,
You used to get 35% of what players lost. If they won you got nothing.
Now you get a percentage of what they wager.
That means that if I sign under you and deposit $50 and play and play and play some slots, where I win and lose and win and lose and it keeps me playing, and then cash out $100, you still get paid on the wagering I did. The longer I play, the more you get.
This is how all the land casinos do it.
You don’t ever worry about whether your players win or lose, and you don’t get your comissions wiped out by winners, ever. What you see is what you get.
If you do the math, you still make around the same percentage on average.
