Those recommendations (Bitstarz & Winz.io) - I looked them both up and they get slated on sites like Thepogg?
On my original post, discovered more, which is a bit worrying - I played the same slot (Esqueleto Explosivo 2) at different casinos (and different owners) and each time I went into the game, it brought up my stake amount I had finished on from the previous casino.
To me that smells of the game itself knowing my IP address and is the game operator themselves who are controlling payout rates etc.
Meaning: I play on that game on one casino and win. I go to another casino and the game knows I've won before, so could potentially reduce payout.
The only reason I'm suspicious is because on both Hyper Casino and Casilando (different operators, which Thepogg shows as highly reputed), the stake stays the same as it was when I played the other.
What do people think:
1. That an individual slot game has an overall RTP across all the casinos it's available on and regarldess of where we play it's going to pay out or not depending on everyone else who has played it across multiple casinos? or ...
2. The payout is independent on each casino it runs on?
3. Something else?
To put that another way, if I bet £10 on a game and it pays out £500, it's the casino I'm on that pays out, not the overall game supplier.
Just trying to work out how these things all work in the background.
