    Solid puzzle … took me an hour to get through on pure logic

    I solved it on my 4th attempt, no idea why made mistakes on 3 attempts.
    It would be a great functionality for penpa to show where the mistake appeared. It shouldn’t be too difficult, as it already keeps the entire stack, unless it’s not trivial to implement checking correctness of a partial solution?
