I did have a thread on this a while back, but most of the people that posted had a pretty high overall RTP. Mine is currently sat at 99.5%.
Up until around a month or two ago it was around 94% pretty consistently, then I had the luckiest month of my life on slots (several 400x to 1000x+ wins, made around £11k in total from £1 to £5 spins), and it rose to about 104% RTP.
Since then I’ve only gone down, and that’s why it’s sat at 99.5% now, which is still healthy.
92% is pretty bad, but it’s all swings and roundabouts I guess – the law of averages!
