Basically there's not many people that would feel comfortable putting $800 in one go at a slot machine, but many end up doing so by putting small notes, $1, $5, $10, at a time, and then trying to recover loses, etc. If you sum up all that they will realize they paid more than $800 even though they wouldn't have done it in one go.
He must be quite rich and have a large initial capital if he wants to use such a large base bet, the casino will call the high rollers. It will be difficult to immediately get a high multiplier with just a few spins if he does 10x spins it has spent $ 8000 maybe players can buy bonus features and expect will produce very good results or at least achieve what is used to repeat the same thing until finally getting a big win because luck has approached him, and players like that will be treated very well by the casino because it is profitable for their business.
People with a higher chance of winning are those who have a large amount of money balance in their wallet, a large amount of wallet do you have a higher chance you will get the chance to win the multiplier if you are just a regular player like me for having a $100 minimum for the bet entertainment satisfaction, and make a bet of $10 per spins, base on my experience I win most of the time but it does not apply to all players after those wins still get loose tons of money due to getting greedy. Also large pool players have the higher chance to be part of the reward system of the platform seems like a rakeback or rewards to you at the same time its a win win situation for the large players.
