If machine wants to earn more money, it needs more people sticking £1 in. People like to win. Letting some hints tips and cheats out into the wild mean 20 people stick £1. 1 to 18 get nothing, 19 gets £6 and 20 gets £10. Machine gets £4.
Punters 19 and 20 taking money out ofthe machine doesn't alter its profitabity. It probably increases it, as 1 to 18 think they can do it, too.
The machine wants people to win
Thats the 'normal' for a non f*cked machine - for ones with emptiers or other things its more like - the machine has a £125 float (so £125 in money from the people who own the machine and various other punters over time).
Persons 1-9 put their pound in and the machine keeps 20% of their money for its profit.
Person 10 comes along and over the course of maybe around 30 - 50 quid takes all the money in the hopper / tubes out of the machine , the box at the bottom will have 20% of what he put in as 'profit' but there is nothing in the machine at all to pay out (they walk away around £70 up)
In the case of 'accounted for' cheats the machine will do all it can to claw back the money it has lost so persons 11-XXX put their pound in and win nothing
In the case of non accounted for cheats , person 11 comes along , puts in £1 and wins £2 , the machine shows empty and the bar / owner / whoever needs to give them money from 'elsewhere'
In the 90's I played a *lot* of machines but never really had any emptiers i just learned the machines , learned when and what to play for , and could hit the skill shots often enough to make money out of them especially when the other players did not.
I generally only found out about the emptier afterwards , but I'll see about writing up a few to explain whats going on if i get the chance to this afternoon - what i would also say is there is often a lot of skill setting up an emptier , and its often very boring to do.
And a very quick one to illustrate that - and i cant remember the damn machine name - it would be a 20p / £8 jackpot barcrest with a cannonballs / soldiers theme and a big feature board at the top.
Basically one of the features was badly coded - it was a skill stop on the number real and the number real went from 1 to 12 but not in sequence , you were supposed to stop it on 12 (or as close to as you can) to get the highest win.
The code also gave you a commiseration prize if you were unlucky to stop it on a 1 , it gave (i cant remember exactly but lets say) 20p and gave you another spin to try and do better.
So most people played , if they got that feature (which was pretty early) , they got a win , the end , or they were unlucky to stop on 1 and got the 20P and stopped it on something better the next time , the end.
However someone worked out that if you stopped it on 1 every time , it just kept going .... and going ..... and going .... so by standing there and hitting skill stops on the 1 , you could empty the machine , it would take a really long time to do but you could take everything from the machine just by hitting the 1 every time.
No idea if this was accounted for in the system or not
Another quick one :
In the upgrade from £10 jackpots to £15 jackpots there was an Ace (the brand) machine with a cowboy theme , one of the features on there was two numbers which would count up on a screen which would move up and down at random in 20p increments , you got what was shown on the screen at the end. The RED (special) feature version of this was a slow climb which on the £10 version always went up to £5 in each column to give you the £10 jackpot.
On the £15 version the bug was that it could not get to £7.50 on each column so instead it went to £7.60
It took those , added them together for £15.20, rounded up to £16 which it knew was not a valid win so put £15 in the bank and 'forgot' it had done that - next play it would still know it wanted to pay out so you could get the feature again , to do the same again.
This one was not accounted for , so the machine would get emptied.
