These medium puzzles are harder than any sudoku or picross I've ever played. You can't just logic your way through them, you actually have to use inductive reasoning. At first I hated them, because I was pretty much just guessing, checking to see if there were errors, and if there were, undoing my guess and trying something else. It felt like I could only solve them through brute force. But the more I try, the better I feel I'm becoming at making good guesses. It's pretty satisfying when I can get one without help
