Logic Masters Deutschland e.V.

• Fortress Fillomino:
  • Divide the grid into orthogonally connected regions and fill each cell with a digit from 1-9 showing the number of cells in the region to which it belongs;
  • Each region must be either strictly larger than all of its orthogonal neighbours or strictly smaller than all of its orthogonal neighbours.
• Full Quad-Rank:
  • All the 2x2 areas of the grid, when read in western reading order, make a total of 36 four-digit numbers.
  • Clues in the center of a 2x2 area show its rank among those 36 numbers, where the lowest is 01 and the highest is 36.
  • 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, ⋯)
