The LnL emptier was basically nudge set up's, Toggle Climb and hitting a twelve or a six on the feature Gold Run (3/4 different speeds if i remember correctly), and just keep banking small wins if the board looks like its not going to give a reasonable win. The small wins would help in the long run as the machine could go on for a hell of rip for a board (just like most Reds then).
I know of only two on my travels, one in South Wales (chipped) and on in Birmingham (unchipped).
Not to sure whether it worked on Paint the Town Red though?
yeah, the game itself looks like an identical re-glass of it, thats not saying the software plays the same though. I don't think I've EVER come across a Paint the Town Red, so can't really comment on that
