Fruit Machine Chat

i recentley walked into my local pub to find a refill key hanging out of a machine, without hesitating i grabbed it and left, i understand that you can change the volume and check the last win and all that crap but when i try it in a machine it first flashes *refill coins* then it will say 1pound x???, a differant amount each time, a what amount will it be playing best, i think its when the amount is as low as possible coz there was one that said 11 and i put a tenner in and won £20, so is it saying to me add this amount for it to be ready to pay out?, any help would be greatly appreciated

what about the £500 machine in service sttions, i put the key in and it flashed up a balance of nearly £25k, what does this mean?

Not sure tbh mate, they deffo don't hold 25k!!

The keys are useless on them anyway as they're more often than not played with notes (and random but let's not go there again )

it wouldnt be 25k, it could be 25000p, tis possible that the 500ers count in 10p's or single pence?
