Like most club machines of the time you had to learn to play them in a way that they didn’t fight you against forcing them, I used to just always go for nudges, £10 was the target to then gamble out.
Using George for the first £10 would often give you an indication of any value in the machine from the off if you hadn’t got any recent info, eg by watching some mug doing a brute force and getting shafted.
The only way I had Cashpots was the usual roll in, you know straight away as it spins slower the same as the hold after nudge type spin.
IMO this is where compensated machines fall into the 'should never have existed' category, they only managed to proliferate in the first place by skirting around gambling regulations by (somehow!) achieving the arcane classification of 'AMUSEMENTS WITH PRIZES', and yet as we all know, even by the £4.80p token jackpot era (1990), there were machines that could save for streaks of £50-£60 (the original ACE Hidden Treasures machines, for example), which in today's money is £143, is that really just 'amusement with prizes'?
I mean, it's all very well for us to sit here in the year 2024, with decades of accumulated knowledge, and also the ability to dissect machines in the emulator in a way that was never possible on the real thing, including doing stuff like 'rewinding time' with VM snapshots to prove certain cheating/dishonest behaviour, like I did with the Betcoms 'switching the box' on the player on their DOND style game.
However, back in the day it was basically just the wild west, with the manufacturers of these machines essentially able to do pretty much whatever they wanted, with all sorts of bonkers compensators, pots, saved for value, anti-force code and all the rest of it.
Specifically in the case of Super Blackjack Club, the original 'correct' way to play this, on earlier chips, was the straight gamble force technique, and then Barcrest pushed out a ROM revision that categorically fought against that behaviour, essentially turning it into an entirely different machine, and reducing its payout by 20% if played in that manner, and there was no requirement whatsoever to inform the player of this. (And of course, when the new ROMs were put in the machine, it'd reset all its internal meters, so anything owed to the player at that point was just lost forever.)
For my money, there's no 'good' way to do compensation, some methods are fairer than others, but fundamentally it's a shit idea and I'm glad it's now dead in the real world, but that it can live on through emulation.
