Cartwheel
- Killer cages
- XV and number dots
- Palindromes
The brief
Normal sudoku rules apply.
Digits in cages must sum to the small clue in the top left corner of the cage. All cages without a clue sum to the same value.
Grey lines are palindromes and must read the same in both directions. The exact composition and direction of the palindromes must be determined.
Digits in a quadruple clue must appear at least once in the four surrounding cells.
Digits separated by a V must sum to 5. Digits separated by an X must sum to 10. Not all XV are given.
