Are you sure you have got the jumper setting in the right place ? check both banks, I could tell you what I've got mine set to if you want, I'm currently playing £250 / 25p @ 78%
I bought this machine yesterday, the £250 jacktpot version, been playing fine, but the instructions they provided are for the £15 version, does anyone have a copy of the £250 instructions.
Also as I have no instructions not quite sure how to clear the bank and refill the machine ready for play, says inside the machine put £12 of 20p in the tube. I did that but when I win prize it can't pay out, as not enough £1 in the hopper and won't dish out the 20p, even though the mech is working fine.
