The difficulty ratings of forcing chains depend on the number of cells involved. You cannot get the total score by writing the technique summary into an excel sheet. You need to check all forcing chains individually.

  • 2 x Forcing X-Chain -- 7 cells each
  • 1 x Bidirectional Y-Cycle -- 6 cells
  • 8 x Forcing Chain -- 4,5,6,4,5,5,5,6 cells
  • 2 x Bidirectional Cycle -- 6 cells each
i don't suppose it will break the record for 7.2,
just curious how to score it (and similarly-rated puzzles posted by Eioru).
