Vaults in the fog
(Published on 20. December 2025, 18:53 by jcgodart)
Rules:
- Normal sudodu rules apply.
- Cages mark "Vaults". Digits in a vault MAY repeat. Digits orthogonally adjacent to a vault may NOT be included within that vault.
- Entropic lines : Every sequence of 3 adjacent cells along an orange line must contain a low digit (123), a medium digit (456) and a high digit (789). Digits may repeat if allowed by other rules.
- Renban : a purple line must contain consecutive digits in any order.
- Digits separated by a white dot must be consecutive. Digits separated by a black dot must form a 1:2 ratio. Not all dots are necessarily given.
- Dynamic Fog: The grid is mostly covered in grey fog. Placing correct digits into cells may clear away the fog in other parts of the grid. No guessing is required.
