159 1-9
(Published on 29. August 2022, 19:24 by PDN777)
Normal sudoku rules apply. 159 rules apply: Each digit in column 1 indicates the position of 1 in its row (that is, if R3C1 is a 6, R3C6 is a 1). The same is true in columns 5 and 9 of the digits 5 and 9, respectively. The numbers on the outside of the grid refer to the adjacent row or column, and indicate that the digits residing between the 1 and 9 must sum to that number (do not include the 1 or 9 in the sum). I think this puzzle is 2 stars out of 5 for difficulty for many solvers. As always, comments welcome!

159 is my absolute favorite ruleset and the puzzle was really fun.
Maybe I got lucky with where I looked, but this was pretty easy for a 2/5. For someone not familiar with 159 it might be harder ofc.
