yin yang john (conway)

(Eingestellt am 8. April 2025, 01:50 Uhr von aqjhs)

This puzzle is loosely inspired by the 3n+1 problem, and if there's a John associated to it it has to be Conway.

  • Normal sudoku rules apply.
  • Divide the grid into two orthogonally connected regions such that no 2x2 area is completely contained in a region. All cells in one region will have a value of 3n+1, where n is the digit on the cell, and all cells in the other region will have a value of n/2.
  • Cells joined by a white dot have values with difference equal to the number on the white dot.
  • Cells joined by a black dot have values in a 1:N ratio, where N is the number on the dot.
  • Clues with question marks have a number to be determined. Different clues may have different numbers and the number has as many digits as question marks on the clue, with no leading zeros.
  • Not all possible dots are given.

Wonderful math-puzzle! Maybe it would be better to write that every clue is an integer? Thank you very much for creating and sharing. I really enjoyed solving this one.
