God no - we don't want compensated fruit machines online...
UnionJackpots.com tried something like this (although of course they tried to do them randomly to remain legal) and they were dreadful...
This thread shows, unfortunately, that there is a lot of misconception, misbelief, misinformation, etc.. about how slots work. I've tried to explain it in the AMA thread, but of course some people will never believe me... but anyway, slots are mathematically balanced so that over time they will of course hit the RTP. The balance is in the law of large numbers...
Here's an example - around 1/3 of all the FOBT machines in Ladbrokes in the UK in any one day will make a loss. Some make huge losses. But the other 2/3's will either break even or make a profit. And because of the large number of games played, in any one day the overall RTP of all the games is pretty much smack on what it should be. And that's how it works.
Some of you, especially in this thread, won't ever believe me - that's fine... but please do one thing for me... If you ask a question or post a comment, at least have the decency to consider the answer rather than just dismiss it out of hand. Remember guys, i have 100% proof that all the slots i've made, and from all the providers i know personally, are not rigged. You guys just have "feelings" and "experiences" which is, i'm afraid to say, not the same as actually having done the maths for games!
