Yes, it seems I did rate it a bit too difficult. I’m still trying to get a feel for the difficulties, and luckely havent been off by more than 1* up til now. It looks like people are used to solving harder puzzles here, so I should consider to rate future puzzles easier then what I think initially. It’s great that the difficulty indication changes after enough people have finished and rated the puzzle^^ I’ll use that to learn, going forward.

pretty easy, except for 2 harder steps.
1) relating to the geometry of the 25 cage.
2) deciding to case col 5

I still consider myself a beginner when it comes to Sudoku, so being able to solve a 3-star difficulty in under 30 min always makes me think it should be rated easier - if I can solve it, anyone can XD This was loads of fun, thank you!!
