Logic Masters Deutschland e.V.

RULE SET:

Normal Sudoku rules apply. Place the digits 1 through 9 in each row, column, and box.

MAGIC SQUARES: There are three magic squares in the grid. All three magic squares are contained within the area of shaded cells. Each magic square consists of a 3x3 grid and each of the three given digits (the 5's) are the center of one magic square. Each magic square contains every digit from 1 to 9. Every row, column and diagonal of each magic square sums to 15.

GERMAN WHISPER (GREEN): Adjacent digits along a green German Whispers line must differ by at least 5. Digits may repeat if other rules allow.

RENBAN (PURPLE): Digits along a purple Renban line must be a set of consecutive non-repeating digits, and may appear in any order.

KROPKI PAIRS: Black dots are a 1:2 ratio. White dots are consecutive. Not all dots are given.

For our color blind friends:

The German whisper lines are all the lines contained within the magic squares shaded area. All other lines are Renban.
