I got no issue with it in itself, the owner can take out what they want.
Is it greed? yes, but it is what it is, its capitalism and there is nothing wrong with taking money out of a business you own.
Away from bet365 tho I found something interesting with problem gamblers.
There is a guy on youtube who posts videos from him betting. Including some fruit machine videos.
What got my attention was that he prefers UK machines to american style machines.
To those who dont know, UK machines are actually rigged, they guarantee a ongoing profit for the operator of the machine, they achieve this by been able to force losses on feature games and such.
So both american and british machines have a target win % where typically the highest it can be set to is 98% I think. With american machines, every roll is random, and the win % is achieved as an average over a period of time by the odds of outcomes. British machines will tend to go on long runs with only small wins or no wins been given out but then suddenly have a happy period where you may get jackpot or two in short succession. What actually happens is on a british machine when it detects its fell too far below the win rate, it will manipulate winning combinations, allow for successful gambles on features an may even activate a invincibility mode, where it forces a winning gamble up to the top feature (the player still has to choose to gamble, if they do they will always win, e.g. betting low on a 2 will roll a 1), once big wins are paid out, it will go back into its normal mode, where it becomes tight and set limits on the feature section how far a player can progress at any given time, e.g. if £4 is the set limit then a gamble on £4 will have a 100% chance of loss.
So this gambler plays on various machines and I watch the video noticing how crappy the british machines are, then he moves onto the american machine, and keeps winning ever few spins, they not big prizes, but he is making a profit, at the end of the video he goes on about how he hates the american style machine, so I asked him on the comment section what the issue was as he made a profit on it and didnt have long spells of no wins, he said the prizes are too low he plays for big money wins only.
After watching some more of his videos where he plays online poker and roulette I work out he is an addict, he does things like carry on when he is well in profit and then loses it all, because he is chasing previous losses.
Conclusion? I feel that the uk fruit machines are designed to keep addicts playing, to be able to pay out jackpots, they have to have long winless runs so they still make a profit, but gamblers like this guy likes them for that reason because of the big payouts.
