OK here's what you do, you need the machine to be consistently giving £2 or more on the start of a feature. You do this by putting anything between £10-£10,000 (depending on the locality to Anfield) through the machine, refusing all wins.
That's stage one, now you need to go onto stage two.
Stage two.
This is stage two.
Stage two is going for jackpot. Keep refusing any sort of win, even Monopoly or no Monopoly. Eventually you'll get stage three.
Stage three.
Here is stage three.
"It's a jackpot"
That was stage three.
Now you need to go onto stage three/section 2. Just keep playing for Deal or no Deal. if you keep taking those features it'll build up the bank dead quick, but for now, you want to keep knocking them back, until you get bored, broke or bolloxed.
Stage five. Collect and run.
Stage four is you need to run the machine dry by inserting twenty, play off £2 and collect the rest. Repeat until it wont take any more notes. Refuse all wins until notey back on. Build up big bank. Collect, collect some more. The looks on the faces of those lads will then be priceless.
£249 off and £4+rep starting. Yes they'll be puzzled as fuck! Good luck!
