Any tricks on the 25 Jp will be the same as the 5Jps. Instead of searching for extremes. Try looking for, "Nudge trick", "Refill key cheat" and "setups".
has anyone tried the force on the £5jp extremes yet?? the reason i ask is because i've got one near me that has started on £2.80 [bells] twice now and also did a slow down bonus today, both classic signs for the force on £25 jp, mine is a bucket loads on 25p a spin and i've made a £12 and an £8 on it in the last 2 visits through milking it.
25p extremes are excellent to make money off. There's a Daunting in Milton Keynes thats 25p/£5, and i think i've never been there and not made £10+ on it. Piece of cake!

I take it your talking milking it. the 2 times i've played it its been lively, probably been filled by kids cause its the holidays. if you think about it you take £2 on £25 jp's most of the time anyway so there is money too be made.
played my £5 JP extreme today, got £6 in front through milking etc, then it gave me a slow down bonus for selector that i hit on super start, the board was 1-1-1 cause i'd already taken the value from the machine and this was my last board anyway. i can see the force costing £20ish [its 25p a spin] and with this slow bonus popping up when its dead i'm gonna stick too milking.
