Vaulted Banquet
- Quadruples
- Vaults
The brief
Normal sudoku rules apply.
Digits in row 1 index the row in which the 1 appears for the corresponding column. Digits in column 1 index the column in which the 1 appears for the corresponding row. Similarly, 9's are indexed in row 9 and column 9. For example, a 4 in r5c1 will place a 1 in r5c4 and a 5 in r1c4.
Digits in small circles must appear in (at least) one of the cells touching the circle.
Digits in "Vault" cages may repeat. Digits orthogonally adjacent to a Vault may NOT be included within that Vault.
