Entropic Circuit

(Published on 10. October 2024, 21:24 by sujoyku)

This puzzle resulted from playing around with entropy lines and quads. I hope it is approachable and fun to solve. Many thanks to all testers on the CTC discord server! As always, your feedback in the comments is highly appreciated. I wish you joyful solving!

- Normal sudoku rules apply, i.e. each row, column and 3x3 region has to contain the digits from 1 to 9 once each.

- Entropy lines: Every set of three adjacent digits on an orange line must include a low digit (1, 2, 3), a medium digit (4, 5, 6), and a high digit (7, 8, 9).

- Quadruple: Digits in a circle must appear in the four surrounding cells.
