Lol...I retrieved the previous year's losses, gradually. That wasn't my best ever run, that took place at Casumo in my old euro account there, made 12-13k euros in a few weeks. Sky Vegas was a disaster for me, I had 94% stats from Bonanza during my total time there, and an incredibly bad 90% on Starclusters. So over the last 2 years, before I ran out of UKGC casinos, I finished about par on it, what I consider to be extremely fortunate. I actually checked bank statements a couple of weeks ago, as I can go back 6 years until when I first played it. It's difficult to be exact, because I lost on The Rapist and Twin Spin etc. too, but based on the assumption I played 80% of my time on Bonanza my net losses over that period are worse than I actually thought, approx 24k and over 30k overall including the sessions I played other slots.
Considering the vast turnover I had on it, I would say my RTP was actually around 95%, it's hard to be accurate. So not great, but not as depressing as if it had been say 92% as that would have made that 24k well over 50k.
Having now had well over a month off of it, I can't say I miss the game or gambling at all for that matter. The game isn't 'bent' but simply has awful RTP distribution due to the high variance and unlike other HV slots, it doesn't seem to make up swings in consistent play. I bet if I had chosen DoA or DoA2 for that period and amount of spins, I would have had numerous wildlines and wins over 5000x on the former, or even 30-40000x on the latter. Just by sheer weight of numbers. And that's the only thing that gets me regarding Bonanza - how daft I was chasing the rainbow of the 'potential' 10k x in the feature when in reality all I got was a third of that twice and a quarter once. And never saw an 8+-scatter trigger, only once got 1000x in the base game. If nothing else, the Bonanza slot is the master of illusion and irrational hopes and expectation. The 'psych-ops' of online slotting.
Looking back, the final year I had on it was my luckiest ever and I am surprised and even grateful it occurred, as it made what would have been a very painful 5-year net loss of nearly 40k into a more bearable, albeit still dreadful one of around 24k. So I am glad I cut my losses, literally and have no plans to return to it even if I can find a new UKGC site or crapto one, if they have the game.
One final word of advice - if you are well down like me, and are enduring a sub-par RTP in the medium term, remove all optimism and expectation from your mindset - you'll NEVER retrieve the situation and that statement carries more weight and reality the longer you've been playing the game.
