Wegen gestern: Ich wollte in dem großen Sudoku auch einmal kurz diese Eindeutigkeitssache zeigen. Für mich persönlich gehört das mit zu den normalen Sudoku Regeln. Wenn ich also schreibe: Normale 4×4 Sudoku Regeln gelten, meine ich implizit, dass eine eindeutige Lösung existieren muss. Gleichwohl kann ich verstehen, wenn ihr das anders seht. Aber nun zu heute:

I got left with a 1 4 deadly pattern. Obviously sorted by the rule (There are only exactly two dominos with a 1:3 ratio). But I read the old rule before I saw it written this way and couldn't work it out.
Still a fun puzzle.
Now onto day 12 .. this may take a little longer!

Hard to understand the phrase: "There are only exactly two edges with a 1:3 ratio" had to guess for the last pair of 1 and 4. Maybe the rule should be "in a 2x2 box, 1 and 3 must always be diagonal of each other".

For me the rule was understandable. Maybe simplify to exactly two dominoes? Great snack thx

I really had a bit of trouble understanding what the last constraint is about and had to reverse engineer that (since my understanding that this refers to neigbouring digits on an edge proved impossible).
I’d rather write: There are only exactly two instances of cells on opposite ends of the grid with a 1:3 ratio.
