Logic Masters Deutschland e.V.

RULE SET:

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

Adjacent digits along a GREEN German Whispers line must differ by at least 5.

The GOLD lines are Nabner lines, there may not be consecutive nor repeated digits along these lines and digits may be in any order.

RED lines are 10-Lines: Each line consists of one or more contiguous groups of cells, each of which sums to 10. These groups of cells cannot overlap; every cell is part of exactly one group. Digits may repeat freely on lines and even within sums if other rules allow.

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

XV pairs. Cells separated by a "X" must equal to 10, and cells separated by a "V" must equal to 5. Not all XV pairs are given.

For our color blind friends:

GOLD lines: box 4 top line, complete column 9, and the column 9 line in box 6 moves down into box 9 to end on a red line. Box 9 two cell line (R9C7,R9C8).

GREEN lines: the two "U" shaped lines in boxes 6 and 8, and the two lower lines in box 4.

RED lines: the two longer lines that both run through box 5.
