Rules:
- Normal sudoku rules apply: Place the digits 1 through 9, such that every digit appears exactly once in each row, column, and box.
- All teal lines are both Region Sum lines and Modular lines.
- Region sum lines: Teal lines are divided into segments by box borders. Each segment of a line has the same sum. Different lines may have different segment sums.
- Modular lines: All teal region sum lines are also modular lines. Every set of 3 cells along the line must consist of a digit with remainder 1 (147), a digit with remainder 2 (258) and a digit with remainder 0 (369) when divided by 3. Digits on a line may repeat if allowed by other rules.
- Difference Kropki: Cells separated by a white dot must be sequential. Not all white dots are given.
