I pretty much do it to get my bonus, but I have won a few times...never more than a quarter, but I have won-it's like any other game of chance- hence the saying 'you can't win it if you're not in it'...
Can't see how it is much fun tbh, looking at adverts! I was doing it for potential winnings but it's a total waste of time. Anyone getting anything out of it, good luck to you, but i won't play it again.
