What Makes Medium Different?

Medium puzzles introduce new challenges:

  • • Requires tracking candidate digits in notes for complex cages

  • • Expect 30-45 minute solve times

Tips for Solving Medium Killer Sudoku

Enumerate cage possibilities early

For each cage, write down all valid digit combinations that sum to the target. Cross out combinations as standard Sudoku rules eliminate them.

Look for cage intersections

When two cages share a row, column, or box, their combination constraints interact. Use this to narrow possibilities faster.

Use naked/hidden singles in cages

Even if you don't know the full cage solution, a single cell might be forced by row/column/box elimination.
