A Bit of 12-Line Fun
(Published on 20. July 2025, 13:42 by ebiggie)
RULE SET:
Normal Sudoku rules apply. Place the digits 1 through 9 in each row, column, and box.
RENBAN (PURPLE): Digits along a purple Renban line must be a set of consecutive non-repeating digits, and may appear in any order.
12-LINES (GREY): Each grey 12-Line consists of one or more contiguous groups of cells, each of which sums to 12. These groups of cells cannot overlap; every cell is part of exactly one group. Digits may repeat freely on lines and even within sums if other rules allow.
For our color blind friends:
Renban's are thick and 12-Line's are thin.

Absolutely stunning puzzle! Great and fun solve. I think only 3 to 4 stars for difficulty, because every step is so elegantly telegraphed. Thank you
