Thinking further, we deposit into each casino so there’s got to be some sort of ‘control’ that stops any one game paying too much. Update on this – playing the same slot on a few different casinos past couple of days and it slaughtered me across the board! Dream would be that secrets get revealed and as a result all those that had losses on slots will get refunds  and those that had wins get to keep them Thanks everyone – I experimented further (chose casinos from ThePogg) and had two windows side by side in the same game (but on different casinos that had 10/10 ratings – both owned by the same group though). So, stick to a casino that tend to give you better gameplay all the time and avoid those that don’t.
