Granular Impurities

(Published on 16. February 2025, 12:19 by Allagem)

I'm finally experimenting with 10-Lines and they are quickly becoming one of my favorite constraints. There's just so much you can do with them! I wanted to mix 10-Lines with another constraint and I thought Minimum cells could create some unique interactions that haven't really been explored before. You want to break each 10-Line into pieces, but the minimums limit how small of a piece you can use. :) This design stuck out of the many, many iterations I explored not because it was the most difficult or featured the most unusual 10-Line sums, but because it was by far the most elegant in terms of visual design, interaction themes, and solution path. I intended to create a slightly harder puzzle, but this is the design that deserves to be published.

This puzzle is also a great excuse to show off my new visuals for 10-Lines that I debuted in Boba the Cat! You can use the pen tool in SudokuPad to fill in the segments of the 10-line as you solve the puzzle to visually represent the logic of the 10-Line! I hope this visual style gets picked up by other 10-Line puzzles - I think it works perfectly! :) I suppose this means I'm advocating for the canonical color for 10-Lines to be white. They are certainly interesting enough to be worthy of such an audacious color! :D

I hope you enjoy Granular Impurities!

Solve on SudokuPad

Normal Sudoku rules apply.
10-Lines: Each white line can be divided into one or more segments that each sum to 10.
Minimums: Each digit in a shaded cell is less than its orthogonally adjacent neighbors in unshaded cells (as indicated by the inequality symbols).

Solution code: Row 5

I'm glad I could introduce 10-Lines to your Sudoku experience! Be sure to check out zetamath's original 10 Lines puzzle! The first is still the best IMO.
