A Ranked Phenomenon
(Eingestellt am 25. Dezember 2025, 05:00 Uhr von Las4one)
Inspired by Xenonetix's A Mathematical Phenomenon. Note that the puzzle is still unique without the dots in the grid, but it might need some bifurcation.
Rules:
- Sudoku: Place digits 1-9 in each row, column and region exactly once.
- Full Rank: The digits on columns and rows, read in both directions, make a total of 36 nine-digit numbers. Cells outside the grid have a value equal to the rank in ascending order among those 36 numbers for the indicated column or row in the direction of the cell.
- Kropki: White dots connect two consecutive numbers, and black dots connect two numbers where one is double the other. Not all dots are necessarily given.
The version without the dots in the grid is also provided for those who are interested. penpa ctc
Enjoy!
Lösungscode: The 9-digit number of rank 21.

It is wonderful that so many numbers could be deduced just by a simple clue like this. Very good puzzle!

Easy to find the rank values, but hard/fun scanning to get the sudoku completed. Great construction. Thanks

A great construction. I thought it was amazing that you had to keep making logical deductions right until the very end - not many puzzles require that. Thank you!
