I think this has been mentioned before, but over my years of using on line casinos there's certainly a pattern to suggest that RTP % trends should really be calculated by software provider rather than by game and casino. For example I've recently been playing IR and Playboy frequently over about 5 casinos. I was getting to a stage whereby I was about to give up and switch back to IGT given my cumulative loss across the casinos overall, as I guess you'd expect over time, although I was getting a few winners. My usual bet is £1.50 per spin.
Then I hit big on Playboy on one of the casinos, winning over £2000 on the running wilds feature, which I thought prudent to withdraw! My experience tells me that I'd be 99.9% likely to lose continuing to bet with the casino I'd won at, so I concentrated on the others. However, ever since this win I cannot win a bean on MG games at any casino. I haven't triggered a feature since and at one point I had over 65 spins at £1.50 per bet which only generated one winning spin which was 75p! Interestingly (and totally my fault of course) I'm nearly £2000 down across the other casinos overall, over the few days since I had the win.
The change in play on MG games since I had the win is very significant and leads me to believe that the RTP "levelling" works by player across casinos by software provider rather than by game by casino. I only subscribe to the random number generator that casinos quote in as much as the "number" generated is predetermined as a win or loss to level the RTP, hence are not random in the true sense of the word.
