Hoping for some words of wisdom.
Match It has developed a fault with its feature reel.
On selecting 'gamble' the feature reel spins but the symbol shown on the feature reel when it (eventally) stops differs to what the machine has determined the result to be, e.g. feature reel stops on '+10p' but the result the machine actually delivers may be '-10p' or 'collect'. It could by coincidence match what appears on the feature reel. The feature reel also spins for far longer than it normally would, i.e. up to 10 sec instead of 2 or 3 sec.
I've attached a couple of vids. Let me know if further images of vids would help.
Any thoughts about where to begin?
