- Every digit from 1 to 9 appears once in every row, column, and region. 9 regions are to be determined. Every region is a set of 9 orthogonally connected cells. One region border is given.
- Cells across white diamonds are in separate regions, and have a difference of the first digit (from the left & top respectively) in their respective rows & columns.
- Cells across black diamonds are in separate regions, and have a ratio of 1 to the first digit (from the left & top respectively) in their respective rows & columns.
- All diamonds are given. (Diamonds that would not be found on region borders are not shown.)
