Normal sudoku rules apply.
159: Digits in column 1 indicate the column in which the digit 1 appears in that row (e.g. if r4c1 is a 6, r4c6 is a 1). The same applies to columns 5 and 9, with the digits 5 and 9 respectively.
Glyphs: Digits along a grey line must strictly increase or decrease.
Have fun, leave a comment if you enjoy the puzzle!
Solution code: Column 3 followed by Column 7

My first indexing puzzle I could wrap my head around. Will probably never be mind favourite variant, but still great puzzle

Top notch sudoku! I love indexing puzzles. Yes, I realize there is something wrong with me, but I do.

Pretty approachable, but I just love the 159s and this was another fun one.

That really nice, not too hard if you have done a few 159's before. Some really nice bits of logic in the shapes though. Thank you!
