Logic Masters Deutschland e.V.

Irregular Sudoku rules apply. Place the digits 1 - 9 once in every row, column and bold outlined region. The 3 or 6 cell regions on the right side of the grid connect to the left side to form 9 cell regions.

Kropki Dots: Digits separated by a white dot are consecutive. Digits separated by a black dot are in a 1:2 ratio. Not all dots are given.

Renban: Digits on a purple line form a set consecutive digits in any order.

Arrows: Digits on an arrow sum to the total in the connected circle.

Rotational Sums of 10: All digits in the grid have a 180 degree rotational opposite. Every digit and its rotational opposite add to 10. Eg. R1C2 and R9C8 must add to 10. Eg. R5C4 and R5C6 must add to 10.

Custom Fog: Most of the grid is covered in fog. Placing correct digits may clear the fog somewhere in the puzzle.
