Apologies if this is common knowledge but my small addition to the rule documentation is that the spinner seems to only function as a scoring device. It seems to have no function in rules progression.
It starts at 1000 per spin and builds the value to as high as 50K per spin. At that value I was able to generate around 1.5 million with a strong shot to the spinner, though that might be an unlikely achievement in the real world, particularly as it seems to reset with each ball.
I think a simple application would be to have the spinner re-light Escape at say, 100 spins or so. If Escape is already lit perhaps it could increase the value (2x, 3x, etc). It would make some logical sense as the spinner animates Jack running.
