Well I looked at the dils based on the pic of switches 13-16 and it was set to 98%!! No wonder!! I have reset it to 70% and have just played out a tenner in five minutes, still plenty of gameplay with features, viva mexico etc just doesnt let me win more than a couple of quid which is just how I want it, Thanks guys!! :-)
You might find 70% a bit tight, quite a few clubs seem to use 72% > 78% (with 72% being the most common I see around here), and when my new clubber comes next week, I'll probably set it to 84% - totally up to you though
