Parity Runs #1: Introduction

(Published on 5. June 2020, 07:25 by Madmahogany)

Normal Sudoku rules apply. The two numbers outside the grid represent the two longest runs of one parity (odd or even) in that row/column. Note that this is just the longest runs regardless of parity (that is, both the longest runs could be odd, for example). Essentially, the row/column is a string of 9 numbers, which can be split into runs of odds and evens. Considering the lengths of each of these runs, the two longest lengths are given outside the grid. For example, if the digits in the row were 145796832, this has runs of length 1,1,3,2,1,1, so the clue outside the grid would be "3 2".

Additionally, there are some Kropki clues in the grid. Two cells separated by a white dot must be consecutive, and a black dot between two cells means one cell is twice the other.

This is part of a series of puzzles I have in mind with this rule set. I was inspired by glum_hippo's Parity Party series when thinking about this rule set. I think it allows for the creation of many hybrid puzzles, so as to disambiguate the grid.

This is an introductory puzzle for this rule-set. If you want to try other hybrids of this kind, here are some links: #2 #3 #4

Update: The previous grid was the incorrect version, as it lead to multiple solutions. This is the corrected grid now. Sorry for the inconvenience.

Solution code: Row 6, followed by Column 9
