1-5-9 O'Clock Rock
(Published on 17. November 2022, 07:42 by meggen033)
Normal Sudoku rules apply.
1-5-9: Each digit in column 1 indexes the 1 in its row (i.e if R3C1=4 then R3C4=1). The same rule applies to column 5 digits indexing 5 in its row, and column 9 digits indexing 9 in its row.
Digits in a cage sum to the digit in that cage's top left corner. Digits cannot repeat within a cage.
Digits separated by an X sum to 10.
Digits separated by a V sum to 5.
Digits separated by a black dot must be in a ratio of 2:1 with on another.

a two star puzzle for sure, you need to know a trick about 1,5,9 puzzles.
Very nice flow until the end, and its final deduction.

Lovely puzzle :D but it felt more like a 2* than a 1* xD maybe it was just me though...
