I'm embroidering this pillow with some lovely pearl buttons. You may ask, "How do I know where the white ones go? How do I know where the black ones go?" I've stitched little Ms for one and Ns for the other.
I don't remember which is which.
Oh, you want to see the pillow? Yeah, that would help. (This is a Masyu or "Pearl" puzzle. But figuring out where the black and white circles go is part of the puzzle.)
Answer Checker:
Hints: The answers will fit an 8x8 grid... And then you want to treat that grid as a Masyu or "Pearl" puzzle, where N and M represent black or white pearls. But you have to figure out which is which. If Ns were black pearls, then the NN at the end of the second row would be impossible. So Ns are white and Ms are black. When you've solved the Masyu, read off the letters that aren't covered by the loop.
