Same here, less than 4 errors, it's just luck

I suppose you could take pictures with your phone as you go and refer back to them to know where they are?

I dunno, I found this one really easy and got it on my second try without cheesing it. Luck has nothing to do with it. All you have to do is pay attention.

I got it first try but must admit that I don't think I've gotten a seed like it since. Get lucky and remember the tiles you do flip.
