- Sudoku: Each row, column, and region indicated by thick borders in the grid must contain the digits 1 to 9 once each.
- Region sum lines: The sum of the digits on a line within a particular region must be the same for all regions the line passes through. The sum applies to each individual visit a line makes to a region. Different lines may have different sums.

- Clones: The two marked grey cells are clones. They contain identical digits.
