Logic Masters Deutschland e.V.

- Standard Sudoku rules apply.

- Cells connected by a white dot have consecutive digits. Not all white dots are given.

- Cells connected by a black dot have a ratio of 2:1. Not all black dots are given.

- The lines found on the grid are "Non-consecutive renban" lines. Digits along a non-consecutive renban line have to be consecutive, yet no 2 orthogonally connected cells can be consecutive along the lines. The non-consecutive constraint only applies on lines individually, which means that 2 adjacent renban lines can share consecutive digits along an edge.

(Note: The non-consecutive constraint also applies when the line turns around and touches itself along an edge. For example, R2C2 and R3C2 also cannot be consecutive.)

Estimated difficulty should be 4.5/5.
