Renban variant
(Published on 8. January 2025, 14:57 by Azvaril)
Hello. I recently created a series of puzzles that I used to introduce my friends to different sudoku variants, along with some secrets and tricks how to solve them. I want to share with you some of them, which are quite challenging and interesting.
Have a good time solving!
Solve on SudokuPad
Normal sudoku: Every row, column and 3x3 box must have all numbers from 1 to 9 exactly once.
Renban line: Digits along a purple line must form a consecutive group, but they may appear in any order along the line.
Partial Kropki: A white dot between two cells indicates that the neighbouring digits are consecutive. A black dot between two cells indicates that one of the digits is twice as big as the other digit. Not all possible dots are given.
Solution code: Row 1, 9 digits left to right.

put the "quite challenging" in the intro in bold. also, there are a few tricks where you can take a beginner to expert in 5 min. roping is not one of them.

40 minutes for me. Spotted the break in early but was slow on working thru the ending. Not massively hard, but certainly not beginner-friendly.

This was fun, but I disagree that this is a 1 star puzzle. I found it more difficult than that.

Woe to the beginner who comes to learn basic facts of renbans and kropki, sees a 1* rating, and expects it to be "very easy"!
This was a nice collection of tricks but I found it 2*, and I already knew them.

Not hard if you know the renban trick

I enjoyed that. Seems quite tough for an intro to renban. Thanks for sharing.

Very elegant logic. I would say this might be a 2* for many. Loved this one. Elegant yet simple
