Quoted from DarthXaos:If skill is a factor, why would a Vegas casino put this in and risk having a Keith Elwin or somebody show up and break the bank on them?
From NanoTechGaming's website:
An above-average Score percentile will result in an above-average probability of winning, but only if there have been sufficient below-average scores in the Database to balance this award.
So as I understand it, the machine's not going to pay out any more (in aggregate) than a similar non-skill-based machine would, but rather when it does pay out it's going to pay the better players more (or more often) and pay the shitty players less (or less often.)
