Logic Masters Deutschland e.V.

R.I.P. for those who died for us all...

Rules:

1. Classic Sudoku: There's exactly a set of 1-9 in each row, column and 3x3 box.
2. Thermometers: Digits on a thermometer strictly increase from bulb to tip.
3. Between Lines: Digits on a gray thread are strictly between the digits in both connected circles.
4. Kropki: Two digits separated by a white dot differ by 1. Not all white dots are given.
5. Renban: Each magenta line contains a set of consecutive digits in any order. For example, 534, 345 and 435 are allowed, but 346 and 565 are forbidden.
6. Region Sum Lines: For each blue line, digits on the line have an equal sum N within each box it passes through. Digits may repeat on these lines if allowed by other rules. For example, r1c1 + r2c1 + r3c1 = r4c1 + r5c1.
7. German Whispers: Neighboring digits on a green line differ at least by 5.

NOTE: All lines are visible, in case of confusion. For example, there is no green line in the cell r2c1.
