Does the casino owner have to pay that amount? or the slot provider pay part of that win, because the slot provider offers an RTP and as a casino owner if the RTP is 95% it means the casino has won more than those $200k to pay for that bet, so, in other words, new casinos doesn't give big wins until the RTP is covered?
RTP is being set by the regulatory body, casino owners or slot providers can't just go and say I want to set the RTP to 95%. So it means that casinos should abide by this otherwise they could be subject to fines. So in your example, it should be the casinos that are going to pay for it.
Yes, but still going to be based on numbers and averages. There could be one big winners in a night, but if you compute it to let's say a month, the casino could still be in the net green numbers because the "house always win".
