All in or All out
(Eingestellt am 5. September 2026, 09:15 Uhr von tigran)
This is my first published puzzle. I've tried to create a new rule that brings forth an interesting pattern. I hope you'll enjoy it.
Rules
- Normal Sudoku rules apply.
- Shade a digit in each row, column, diagonal, box, and relative position (in the box) such that for each shaded digit D in column C, row R, box B, position P either D=C=R=B=P OR D≠C≠R≠B≠P, i.e. D, C, R, B, P are either all the same or are all different. (The boxes and the relative positions are numbered starting from the top-left corner, moving left to right, row by row.)
- Shaded cells form a complete set of the digits 1-9.
- Digits do not repeat along the marked diagonals.
- Digits separated by a white dot are consecutive.
- Digits separated by a black dot are in a 1:2 ratio.
Lösungscode: Row 1 from left to right

Dear itsid, the shaded digits need to be a disjoint group, which should be found by the solver. You're right that the puzzle is not an overall disjoint puzzle. Thanks for pointing it out, I'll remove the tag.

uhmmmm... how is this a disjoint group puzzle?
remove the tag very misleading

this puzzle was quite enjoyable, thanks! I felt that discovering the shaded digits required a bit tedious work, but it was quite smooth after that. Couldn't really decide if it's 2* or 3* but it feels closer to a 3.

Clarification of a rule.

SudokuFan D≠C≠R≠B≠P means all are different.

Does D≠C≠R≠B≠P mean that D, C, R, B and P are all different or just that D≠C and C≠R and R≠B and B≠P?

Added additional tags to better describe the puzzle.
