Yeah , the ones I used to play on had a habbit of not paying out as well , but I got my own back.
I was playing on one whilst I was on hols at Butlins once. There were two lines which never paid out , despite the red and black numbers on them. But then I managed to get my coin onto a number 6 , and it paid out like about 50p. So , I tried it again , and it eventually did it again. Everyone kept looking at me as the coins kept rolling over the glass. I`m sure they thought i`d been banging it or something.
I had to leave for dinner not long after , but I was gonna go back the next day and try and clean it out. Strangely , the machine had vanished overnight.
Ah Butlins , those were the days. A bit like staying in a `Chicken Run` theme park , and just as hard to escape from as well.
