So I'm banging my way through the Witness and loving it for the most part. There are a few things that I have found a bit frustrating (but that's probably due to my lack of understanding the rules fully) but overall I'm really enjoying it. There is 1 rule set though that I can't seem to fully grasp... Those damn Tetris pieces! I understand what they want me to do (outline the shape) but what I don't understand is what dictates when you can flip/rotate the shapes to get them to fit in your outline. Every time I think I have it figured out, I come across the next Tetris piece and the rules seem to have changed. Am I the only one seeing this inconsistency? Can someone please explain to me the rules I am suppose to follow here? I know the crooked ones mean you can rotate them, but other then that I'm not sure when you have to leave them as is and when you can flip them etc.
Thanks for the help!!
