Parity Party XXX, "Checkered Past"
(Published on 13. November 2024, 14:12 by glum_hippo)
Normal Sudoku rules apply. Each row, column, and 3x3 box contains the digits 1-9 exactly once each.
Parity Party: A number at the edge of the grid indicates the sum of cells encountered when moving through the grid from that vantage point, UP TO AND INCLUDING the first odd or first even digit. For example, a 15 at the bottom of a column could indicate something like 7-8, 8-7, 1-3-5-6 or 2-6-4-3 (among others) when reading up that column... but not 1-2-3-4-5 or 2-6-3-4 etc. That is, the parity of the farthest digit must deviate from that of the others. If the clue is less than 10, it's possible that it simply reflects the value of the first-seen digit, i.e., the sum of zero evens and one odd, or vice versa.
Battenberg: Wherever a 2x2 area consists of two odd and two even digits in a checkerboard pattern, a little checkerboard symbol is marked. All possible Battenbergs are given.

A surprisingly clean puzzle overall that used both constraints pretty well!
Surprised how this doesn't get a lot more solves considering how smooth the solve path is, but it may be because parity party is still awkward to scan for some people :c
