Logic Masters Deutschland e.V.

• Normal sudoku rules apply.
• Ciphered Full Quad-Rank:
  • All the 2x2 areas of the grid, when read in western reading order, make a total of 64 four-digit numbers.
  • The letters ABCDEFWXYZ represent different digits from 0-9.
  • Clues in the center of a 2x2 area show its rank among those 64 numbers, where the lowest is 01 and the highest is 64. (Clues may have leading zeroes.)
  • One or more equal numbers are considered to be at rank N when there are N-1 numbers of strictly lower rank. (For example, we say there are three numbers in rank 20 when there are 19 numbers of lower rank and the next rank will be 23, i.e. the ranks could go ⋯, 19, 20, 20, 20, 23, ⋯)
