And is it worth trying to recreate one? I would imagine it's already too saturated. Either way, I was mostly curious about how much these guys actually make (margin-wise). If anyone had some insight on this, I'd love to hear.
Your choice and its indeed saturated.Gambling sites do really make good money this is why we do see new gambling sites do launch even the games being given is already on the market for how many years and thats why they end up on failure due to lack of interest because a certain gambler would always go the top ones than on newly ones which is normal.
From what I know there's only one field of online gambling were it is still possible to create something which will be in demand among gamblers. It is poker. With the recent closing of poker section by established gambling sites a niche has been created and I constantly see like poker fans play on crappy sites just because they love the game. I'm talking about poker tournaments and table games where people can play against each other, not about video poker which is more like a slot game to me.
There are actually gambling sites that do offer poker but later on they do remove it due to lack of demand.I agree there are really gamblers who do seek out these card game but not totally even on those dice or slots.
