159 Crunchy, Not Sorry (Lockout Lines)
(Published on 5. October 2021, 13:12 by riffclown)
Like the Candy, These puzzles come in Pairs.
This is the crunchy companion puzzle to You got your 159 in my 159.
Normal Sudoku, Lockout Lines and some 159 Rules apply.
159 Rules apply to shaded Red Cells ONLY. Each digit in column 1 indicates the position of 1 in the same row (that is, if R5C1 is a 6, R5C6 is a 1). The same is true of columns 5 and 9, regarding the digits 5 and 9, respectively.
Red Shaded Squares signify digits in columns 1,5,9 that would be correct under 159 rules.. All such digits on those columns are marked. eg. If a 5 is in column 2 and the cell in that row in column 5 is not red. then that cell CAN'T be a 2
Lockout Lines - Digits in directly connected Diamonds must differ by 4 or more and may not be repeated on the line. Digits on a line must fall 'outside' the range defined by their diamonds. Line digits may repeat if allowed by other rules.
Author Note

Very enjoyable twist on the standard 159 - the negative constraint is quite refreshing!

Love the negative 159 constraint - very creative. And quite fun too.
