Arrow Spine Indexing
(Eingestellt am 20. März 2023, 11:58 Uhr von Die Hard)
Normal Sudoku rules apply. Digits on an arrow must sum to the digit in the attached circle. Digits on arrows (including the sum) are also used to position the digit's column in its row. For example, if R3C1 was a 6, then 1 must be positioned in R3C6.
Lösungscode: All 9 digits in row 1.

Very nice! Funny how older puzzles seem so much easier these days. The indexing combined with experience in 159 logic made the break-in not too hard to find and the flow was really smooth which led to a fairly quick solve. I rate it 2.5 - 3 stars, in 2023 probably higher. I had a blast, thanks!

Very nice puzzle once the flow was understood.

Tough challenge with some really cool and fresh logic. So easy to get into automatic indexing mode.
