Understanding Sudoku SE Rating Scale

SE Rating is a scoring system developed by Sudoku Explainer that measures the difficulty of sudoku puzzles. The rating is determined by the complexity of techniques required to solve the puzzle.

  • Beginner (0-1.5): 1.0 - 2.5: Beginner level (Naked/Hidden Singles)
  • Easy (1.5-3.0): 2.6 - 5.0: Intermediate level (Basic techniques)
  • Medium (3.0-5.0): 5.1 - 8.0: Advanced level (X-Wing, Swordfish)
  • Hard/Expert (5.0+): 8.0+: Expert level (Advanced chains, forcing nets)

How Sudoku SE Rating Calculator Works

The SE Rating system analyzes the difficulty of techniques required to solve sudoku puzzles. Each technique has a specific point value, and the most difficult technique required to solve the puzzle determines its overall rating.

  • X-Wing & Swordfish: XY-Wing, XYZ-Wing (6.0-8.0 points)
