I fell for the fake rather too often. HAHAHAHHA - so cooooool! :)) Barged my way through it eventually in 17 steps. For whatever reason I can't get to like these busy block fields. I got this straight off as it was the incorrect solution I was using for the previous practice. I was missing something quite obvious, couldn't get less than 15 off. % stars for confusing me for ages. Pretty tricky for kindergarten IMO.
