OK, I'll try to be as neutral as possible.
As you all know I have been playing this slot very regularly and had both, great times and bad times and as well as the real ugly times.
However, we seem to be all fixated on the statement from
BTG that bonus rounds happen on average 1x in 450 spins only because they pay on average over 100x bet. Hence, we do expect that every bonus round should go up to x20 multiplier and produce some big wins leading to a daily killer screenshot.
But what we forget and to keep the maths simple, if one bonus round ends with a 1,000x bet win that means there have to be 10 rounds with very low results. Nothing different as with other slots. How many times have we gone 500+ spins on DOA, TS2, IR or other favorites without a bonus round and then finally hitting it only to be served a 2x - 5x bet "win".
I don't have access to the details how the RTP is distributed on BTG slots, only got Netent sheets. e.g. to keep it comparable I took NRVNA which has as well only Free Spins plus rather high base game pays and no other features just like Bonanza.
Please remember, that this is the theoretical distribution which has been established by the math model and probably a few billion test spins. Deviations in both directions are absolutely normal, otherwise it wouldn't be a random game.
Hence, it doesn't ring any alarms when I see somebody doing 1,000 spins on Bonanza and ends up with a 73% RTP or has a few bonus rounds in succession with measly returns far below 100x bet. I had those periods too, just like anyone else.
Meanwhile, I have restarted more than half a dozen times the trophies for Bonanza at VS, plus hammered it considerably at
Rizk and Betat, yet I do not see any big difference to other slots. In contrary, I get more often longer sessions with my balance on Bonanza, even without a bonus round, than on other slots, e.g. BoD or DOA.
Bonanza can be a beast or an ATM in a matter of hours and the long waiting time for a bonus round is designed to appeal on the gambler's mind, e.g. "I played it so long, it must hit now soon". Hence, we are chasing that GOLD with a vengeance, only to be mostly deeply disappointed and then come onto CM to vent our frustration. Myself, I went in excess of 3,500 spins once to hit the bonus round, losing a ton in the process and getting a meager return after the 12 spins finished rather quickly.
Getting hooked up on that GOLD is dangerous and anyone prone to that should set a limit of spins before leaving the game and trying their luck on another slot, damn'it VS has over 2,000 available, yet we all stick to maybe 10 - 12 all the time, whereas 2 - 3 from those are getting the main share.
