Nuts and Bolts Puzzle

Although to got stuck on 75 I found that if you remove the correct pegs the pieces will move even if you haven’t placed the screw again. Meaning… typically you pull a screw out and nothing moves till you place it again. This wasn’t the case on 75. And I’ve found several others going fwd that are misleading as well. Another thing I don’t like about this is you can get one puzzle that is incredibly hard and then after that, stupid easy puzzles. Like what I would expect in the first 10. Anyway… just reached 100… I might keep it but the other one I found I like better. Add portrait mode AND a ‘back’ button for ONE move and that would get more stars. As of now, you can play, or start over. That’s it.
