OP and everyone, at the end of the article, it says "Contrary to rumours, he is not actually prohibited from visiting any of the city’s popular areas; rather, he simply encounters significant roadblocks from some locations that wish to keep him out." Dana White clarified that “It’s not that I’m banned from casinos, it’s just that they don’t want me to play there.”
He's just given a certain limit. He's not banned.
Yes but they do offer high roller gaming in the first place, which shouldn't surprise them that high rollers also come to them.
But think about the interesting complexity here: on the one hand they want players to know that their casino is provably fair and that there are huge payouts possible because those payouts get very likely publicly known. Maybe not necessarily who won it, but that someone won it, which then again is good advertisement for them. On the other hand if they restrict or ban players who won big time, how will other high rollers react to that? They have reason to believe that they get banned as well. Although I assume that in any case they pay the player the money. But if those machines are provably fair, I don't fully understand why a casino would ban a high roller. He was lucky and that was part of their calculation.
They offer high roller gaming of course. They offer all kinds of VIP treatments and privileges. That doesn't just come in an exclusive table, lower house edge, high maximum, etc. This also come even in non-gambling related perks like complementary presidential suites, wine, meals, etc. But all of this is with the assumption that the casino would earn from them because the rule is that the house always prevails.
The house edge always wins in the end. But when luck comes into play and these high rollers are racking up millions, that's the time the casino would start to worry a little and do certain things to somehow control the lucky gambler. Limiting bets is one of them. The expectation is that these rich people are just throwing money away for having nothing else to do with their time and riches. But sometimes luck changes things.
