159 Renban
(Published on 2. August 2022, 03:21 by mathpesto)
Rules:
Normal sudoku rules apply. Digits on a purple line form a set of consecutive digits (in any order). A digit in column 1 indicates the column in which the digit 1 appears in that row. Columns 5 and 9 have the same rule for the digits 5 and 9 respectively. (For example, an 8 in R7C1 tells you there's a 1 in R7C8. A 3 in R2C5 tells you there's a 5 in R2C3.)
Puzzle:
Solution code: Rows 4 and 5 (no spaces, 18 digits)

Thank you. Took me while to break in but once I had my lightbulb moment it all flowed from there in a beautifully signposted solve path. Very enjoyable and satisfying.

Quite an easy puzzle for a grid that looks so empty. 159 is a really powerful constraint. Thanks.

Really weird how I kept misunderstanding the way the renban lines in col 5 works, but quite a funny flow as well :)
