Logic Masters Deutschland e.V.

Rules:

• Overlaps: Every little square is the center of a 3x3 box. Fill the grid with the numbers from 1 to 9 so that in each row, column, and aforementioned box each digit occurs exactly once.
• Digits on renban lines form a set of non-repeating consecutive digits in any order. Digits on double arrows lines sum to the same total as the digits in the attached circles.
• Digits outside the rows of the grid are skyscraper clues. They give the number of digits in the row the clue 'sees'. Digits obscure smaller digits from vision.
• Miniature deconstruction - place 6 standard 6x6 Sudoku boxes into the grid that are 3 columns wide and 2 rows tall. Each box must contain a complete set of the numbers 1 to 6. These boxes may not overlap. (You need not place a box in every location would could be placed).
• Variant full rank - digits within the deconstruction boxes on the columns, read in both direction, give 18 numbers with zero to six digits. Clues outside the columns give the rank of that column from that direction, with 1 being the lowest rank, and 18 the highest. There are no ties in rank.
