The Fifteenth Day of Christmas

(Published on 18. December 2022, 07:01 by cristophermoore)

Standard Sudoku rules apply. Each purple line sums to 15, including the thermometer. Digits cannot repeat on a purple line. No two purple lines can contain the same set of digits. Digits along the purple thermometer must increase from the bulb end. Digits a knight's move apart must be different.

Feedback is very welcome!

What in the world would a 'satisfying headache' feel like?

Extra challenge: Solve the sudoku without using the thermo. (as in, assign one of nine colours to each cell, such that colours do not repeat in a row, column, or box.) You may use the thermo for the final bit of disambiguation.

Cris: good point. actually, you don't even need the thermo to disambiguate :-) but I think it makes the solve a lot smoother

A great puzzle! I would definitely up the difficulty rating to 4 or even 5 stars though haha

Cris: I thought I would leave that to the solvers :-)

Awesome! Had a lot of fun doing this! Although the possible combinations of 15 and how they fit together made my head hurt :) :)

Cris: thank you! I didn't mean to induce a headache :-O

Michel: No worries. It was a satisfying headache :D
