Scrambled X (Eggs)
- Anti-king
- Kropki dots
- XV and number dots
- Arrows
- Negative constraint
The brief
Normal Sudoku rules apply. Numbers which are a chess KING's move apart cannot be the same digit. Numbers on arrows sum to the number in that arrow's circle. Numbers may repeat on arrows, if other rules allow. Numbers with an X between them sum to 10. All possible X are given. Numbers with a white dot between them are consecutive. Not all possible dots are given.
