If youre barred from an arcade how about revealing which machines are in that arcade and posting it on this site? This will attract pro players who know and favour certain machines to go and rape them at their own leisure...
Cant say Ive ever been ejected, but then Im far from a pro..the only tricks I know are the vivid ones and generally which machines to avoid and which can often give a quick jackpot...
I must be te only person in the world who doesnt know an tricks for jackpoteers...unless the best one is knocking back IM by taking £1 red?
