One is easier than the other. The third one is harder!
My recollection is every third turn rotates a specific pattern of tiles. I worked one portion at a time, and used the first two rotations to get the tiles aligned or as close to that as I could, and then used the third rotation to move tiles that were not relevant to the portion I was working on. Eventually you will have to move tiles that are already aligned, but I simply moved them four times, which put them back to where they were originally.
Its a bit repetitive but it works.
Also, if you exit to the desktop and return, the puzzle will be back where it started. Which means you can reset if a walkthrough becomes available with step by step instructions.
