## The Power of Two

(Eingestellt am 16. Oktober 2021, 02:49 Uhr von starwarigami)

• Normal Sudoku rules apply, along with the following additional constraints:
• Anti-Factor Lines
• A line of length n must sum to a multiple of n,
and may not use any multiple or factor of n other than 1.
• e.g. a line of length 4 may not use the digits 4, 8 or 2
• Digits may repeat on a line if permitted by other rules.
• Killer Cages
• Digits in cages must sum to the indicated total.
• Digits may not repeat in a cage
• Disjoint Sets
• A digit must appear in a different position in each 3x3 region

Lösungscode: Row 6 (left to right) Column 4 (top to bottom) - 18 digits, no spaces

I think I'm getting to like the disjoint set rule. Fun puzzle!

You missed an opportunity here to have the length of the anti factor lines be 16 (a power of 2) instead of 18…. ;-). Also second what Rick said about needing to mention disjoint set rules apply.

The notes here don't mention it, but CTC rules say its also disjoint subset rules.
