I was playing this Impulse offering a few days back when it was close to JP and it dropped in the red lines by itself..always a good sign that you're almost there. Don't remember what it was called but hit the feature where all the columns flash up and down quickly and I hit 11 o'clock rock...the highest feature on the trail. Great..I thought it's gotta be at least £25 and sure enough would have been except that whilst spinning in the first win of many that accumulate to £25 the 1st reel slipped out of line and I ended up with a melon/pear/pear and it said cash win..£0.00 ! It then offers a repeat chance which obviously goes to yes and it spins another losing spin and says cash win £0.00...five minutes later same situation as the reel obviously can't reset itself without a power down. Let the bar manager know and we switched off/on and gameplay was reset to bottom reels. Soon got the JP again though as it was obviously still ready to give that out. Funny though as I thought all machines electronically knew what the reels should be and the physical reels were just the portrayal of those electonic registers for us human beings. E.G a nudge wink always slips the first reel out of sync in one of my locals..sometimes it gets 2 fruits out of line, but as long as you know this then you can still play it..ie it the £25 red 7's can look like single bar/seven/seven and it will still pay. Although some people think they are being done when it actully looks like 7/7/7 when the reels are out of sync and wonder why they are not being payed.
