Greek Key

Standard sudoku rules apply: every row, column, and box must contain a complete set of the digits 1-9.
Modular lines: every set of three sequential digits along a line must contain a complete set of residues modulo 3, i.e. one digit from {1,4,7}, one from {2,5,8}, and one from {3,6,9}. Digits may repeat on a line if allowed by other rules.
XV constraint: Digits separated by an X sum to 10. Digits separated by a V sum to 5. Not all possible X's or V's are necessarily shown.

This is just fantastic! The digits are almost irrelevant for the beatiful logic. Congratulations and thanks for the fun!
>> Thank you! We're so glad you enjoyed it; we love the logic of modular lines :)
