Logic Masters Deutschland e.V.

So ChinStrap kindly asked for a full quad-rank tessellation puzzle (more like a full tri-rank), and here it is.

• Tessellation rules:
  • Place digits from 1-9 in each square and octagonal cell.
  • Cells sharing an edge can't have the same digit.
  • Each horizontal row and vertical column contains a non-repeating set of consecutive digits in any order.
• Full Quad-Rank:
  • All sets of three cells coinciding on an internal vertex of the grid, when their digits are read in western reading order, make a total of 64 three-digit numbers.
  • Clues on an internal vertex of the grid show its rank among those 64 numbers, where the lowest is 1 and the highest is 64.
  • 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, ⋯)
