- Killer Cages: Digits in cages must not repeat and must sum to the number in the upper left corner of the cage (if present).
- Extra Regions: Every shaded region must also contain the digits 1 through 9 without repeats.
- X/V: Cells separated by X must sum to 10. Cells separated by V must sum to 5.
