- 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.
- Line colours are cosmetic and carry no further information.

Difficult, rewarding, third time was the charm. I knew a certain "digit" had to be placed, but could not get it to fit until I placed a different certain "digit".
