Endangered birds: Fruit Dove
(Published on 23. July 2023, 20:11 by olima)
Rules: Normal Sudoku rules apply.
Adjacent digits on green lines differ by at least 5.
Box-Indexing: All blue cells are box indexing, i. e. a digit A at position B places a B at position A in that box. E. g. a 2 in R4C9 (position 3 in the box) places a 3 in R4C8 (position 2 in the box).
Col-Indexing: The red cell indicates the position of the 5 in row 2.
Row-Indexing: The green cell indicates the position of the 5 in column 5.

Great fun to play. But either I had a bad day or this is much harder than most 1 star puzzles. Thx for sharing.

I usually dread indexing but this made it simple to follow the path. Thanks!

I'm impressed that symmetry is only broken by the left-to-right convention of our numbering system! Great puzzle.

This was just so much fun to solve. I love the 1-5-9 sudokus and this was just a lovely variation of that.
Thanks for the puzzle olima!

Great puzzle! I inched along, step by step, but there was always a next step to find.
