2 Star Sudoku

(Eingestellt am 4. Oktober 2025, 22:00 Uhr von ThePedallingPianist)

After a series of puzzles that ended up harder than intended - basically my entire back catalogue to be honest, but several recent puzzles in particular - I really just want to know if I'm even capable of setting a 2-star difficulty puzzle with a concise ruleset. Many thanks to several testers, some of whom found it easier than 2-star and some of whom found it harder, so who knows how this will go...

Normal 6x6 sudoku rules apply.

Pink lines join consecutive digits.

On each star, no two pairs of orthogonally adjacent digits may have the same sum. (Cells touched by a star have been shaded in case of emoji inconsistency.)

Acheived your goal and still kept it really interesting in unexpected ways.

it is important to aim for objective standards in the difficulty rating.

first of all, with nothing to "bite on", we use basic sudoku. if that was enough, it would be level 0 (gas). but it runs out pretty quick, so you investigate the star. and that produces no results, so it's level 2. bottom line, you will need to do some casing, using long chain bifurcation, OR you use some advanced techniques, which makes it level 3. 3 such steps are needed. that's enough to put it to the upper end of level 2, but not level 3.

another way: ask:
a) if a "beginner" can do it comfortably - level 1
b) with a lot of effort - level 2
c) hardly at all - level 3

This may be a 2-star puzzle for difficulty but you're a 5-star setter in our hearts.
