It took me quite a few rounds to make it click but I think I finally understand the rules. When you realize that the main number on the white tile has nothing to do with the main number on the black tile beneath it, and that the main number on the white tile turns into the top right number in the tile, I can from there begin to figure out the puzzle. I don’t know if I’ll ever not find that confusing, but when I can work with it it’s a good puzzler!
