Had a first go on Big Bass Vegas 1000, took 97 spins to get the feature and paid 72.6x
the first 96 spins, were 84 dead spins, and 5 LDW (Losses disguised as wins) thus 89 losing spins.
the rest were 3 equals and 4 profitable spins. best base win was 5.5x (spin #18).
the first 96 spins the RTP was 23.75%
after the feature the RTP was 98.35%
this was on the 94.52% RTP version.
I've played this one a bit and didn't find it too bad. Features came in pretty quickly while I didn't notice any longer dead spins spells either. Didn't get any notable wins on it but all in all a typical Big Bass - for better or for worse.
I was just playing the newest one: Big Bass Vegas 1000. Now, this was brutal. 250x gone in no-time. Feature came in after 300 spins but could only salvage a small portion of that. Looks equally brutal to BB Splash 1000. Probably won't play again.
