Hex
Here is my second quartet lines puzzle. This one should be a bit harder.
Rules:
- Standard sudoku rules apply: The digits 1
through 9 appear in every row, column, and
box.
- Quartet Lines: Red lines may have no more than 4 different digits.
- Cages: Digits in cages cannot repeat and
must sum to the value shown in the upper
left corner of the cage.
- XV Pairs: Digits in cells separated by a V sum to 5. Digits in cells separated by an X sum to 10. Not all possible Xs and Vs are necessarily given.
