Is it possible for a casino to go bankrupt because a player gets a very big win?
I think maybe that's hard to happen if we look at casinos that are already big and well known. But suppose there is a new casino, and there are some players who are very good at playing, so they can win continuously, can the casino go bankrupt? or do they already have an algorithm or a way so players can't keep winning?
I don't think this can ever happen. Wagers from gamblers are not the only ways that casinos make money. There are other ways casinos make money that is in their business model. Some land based casinos have bars, lodging facilities, and other things attached. Therefore, no matter how much a wining a gambler makes, they'll make payment comfortably. This is however not for very small casinos without investors. Small casinos may not be able to handle large winnings. It may not bankrupt them but it would have grave consequence on the business.
