Logic Masters Deutschland e.V.

Another collab with my daughter! She randomly drew the shape of the Renban line, and I liked it so much that I built something from it, leaning into some of the similar set-up we used last time.

----

Rules:

- Normal Sudoku rules apply.

- Renban - digits along a purple Renban line form a set of consecutive numbers in any order.

- German Whispers - adjacent digits along a green German Whisper line differ in value by at least 5.

- Region Sum Lines - blue Region Sum Lines are divided into segments of equal sums by a region border. Different RSLs can have different values.

- Ratio Kropki Dots - digits separated by a black Kropki dot have a ratio of 1:2. No negative constraint.
