No idea, but it always makes me laugh when you see a fruit machine with the start button flashing away in the background on either Eastenders or Coronation Street, or someone pretending to play it when it is obviously in attract mode.
Note to players if you get a bell on reel 1 and reel 2, you get the nudges again, so if you get the nudges, try to get bells reel 1 and reel 2, collect, and then you get the nudges again, nudge the other one on reel 3, then gamble. You get a lot of jackpots doing this. This trick paid for my lunch a lot back in the day.
When you open a new layout for the first time, and only once at the first time, a box pops up for about 10 seconds saying that if you have paid for this layout/DVD you have been ripped off/conned and some URLs pointing you how to download the layouts for free.
