For my last upload of 2025, I'm posting my first puzzle using the Vaults constraint. Hope you all enjoy - happy new year!
----
Rules:
- Normal Sudoku rules apply.
- Vaults - cages mark vaults. Inside a vault, digits may repeat, but digits orthogonally adjacent to the vault may not appear inside the vault.
- German Whispers - neighboring digits on a green German Whisper line must differ in value by at least 5.
- Dutch Whispers - neighboring digits on an orange Dutch Whisper line must differ in value by at least 4.
- Renbans - digits on a purple Renban line form a set of consecutive digits in some order.
- Ratio Kropki - digits separated by a black Kropki dot have a ratio of 2:1. No negative constraint.
- X pairs - digits separated by X sum to 10. No negative constraint.
Accessibility note: The small squares set entirely in Boxes 4 and 8 are Dutch Whispers and the pentagons set entirely in Boxes 2 and 6 are Renbans. All other lines are German Whispers.
