159 Masked Killers
(Published on 17. November 2021, 21:52 by knewt)
Normal Sudoku rules apply
Standard 159 indexing rules apply: Each digit in column 1 indicates the column where the 1 can be found in its row (eg, if r2c1 is a 7, then r2c7 is a 1). The same is true for column 5 (indicating 5s) and column 9 (indicating 9s).
-
Standard killer cage rules apply, with some additions. None of the cage totals are shown. All totals must be made from the digits 1,5,9, and all cages must contain at least one (but potentially more) of the digits from the total.
eg a cage total of 19 is valid, and if used the cage must contain either a 1, or a 9, or both.

Phew it was tougher than I thought. Especially the start is not easy to see.
