Nonsense Negatives

(Published on 15. September 2024, 17:43 by Elytron)

Some time ago, I saw some people setting 3x3 sudokus, where you need to fill the grid with the digits 1-9 once each so that they fulfil some typical sudoku constraints. I found this medium to work well for creating puzzles with negative constraints for some rules, you would usually never expect to see them on. This is how this small puzzle set of small puzzles came to be!

The puzzles roughly increase in difficulty, where the last puzzle is a bonus puzzle, as I haven't found a very clean solve path for it, but maybe you can!


Puzzle #1
Digits? Nine!
Lines? Nein!
Puzzle #2
Odd, Are There
Even Lines?
Puzzle #3
Renban Out of
Clues? Dot Worry!
Puzzle #4
Ditch the Dutch

Bonus Puzzle
Put Down Your Bows

Solution code: Row 1 of the first four puzzles (from left to right).

The rule set for you second puzzle is incomplete/incorrect. I looks like you meant all X and V's are given, not just V's.
----
In the fourth puzzle you don't mention the lines may only move orthogonally.
------
The puzzles were fun, but the solution code is not accepted. The third one was the hardest for me.

Thanks for the telling me about the mistakes. For the 2nd puzzle, only the X's are given, but I messed up copying in the rules. You're right about the 4th puzzle and also the solution code, which I accidentally made r1 of all 5 puzzles. All is fixed now :) -Elytron
