Based on Reese's Chunchiest Candy Bar ever.
Normal Sudoku, Lockout Lines and some 159 Rules apply.
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.
Solution code: Row 3 followed by Row 9 left to right, no spaces, 18 digits

Very nice. I'm liking this rule set. Would have said it's not 4* - more a high 2* for me :)
--Thank you. I think the difficulty kind of averages out to a low 3 but, given that it is two very new rule-sets (Lockout and Broken 159) in the same puzzle, it kind for depends on the solver's grasp of both constraints.

Another lovely broken 159 puzzle! Great continuation of the series.

I found this a step up in trickiness from the prior two but no less fun.
