0In this video, I demonstrate how to spot and apply the Swordfish technique in a Killer Sudoku puzzle.
Rather than breaking down the logic of the technique itself, I focus on how to recognize when it might be useful and how to actually use it to eliminate candidates.
This is a practical example for those who already understand the basics of Swordfish, but struggle to find it in real puzzles.
