Logic Masters Deutschland e.V.

Collaboration between thoughtbyte and europasky. "Cages are pretty."

Normal Sudoku rules apply, additionally:

1. Renban: purple lines contain sets on non-repeating consecutive digits in any order.

2. Antiknight: cells a chess knight's move apart cannot contain the same digit.

3. Kropki pairs: black dots separate digits in a 1:2 ratio; white dots separate consecutive digits. Not all dots are necessarily given.

4. Digits along grey lines must have a difference of exactly 4.

5. Cells with grey squares contain even digits.
