Wildfire, Dambuster, Italian Job...only £5 worth playing purely because you know you might run it into the £75s quite easily as long as there dropping. Only other £5s i play for enjoyment are beer guides and king kebabs or revolutions. £5 really dont result in profit and you know it.
I never bothered with £5 machines (watched someone put £40 into a £5 Pay Cheque before, still offering nothing!) until I came across a £5JP supernova in the train station near me. Alway's being played and it streaks quite a bit as well, have had it go for 7 supernovas in a row before!(obviously this doesn't happen much though) Quite often walk about £20 to £30 up. Changed my opinion of £5 machines entirely!!
