Medium Killer Sudoku

Medium Killer Sudoku adds denser cage interactions. You need to blend cage totals with row, column, and box restrictions to keep progress steady.

At medium difficulty, cage sums start interacting across multiple regions, which creates richer deduction chains. You will rely more on candidate management than direct placement.

Map cage combinations early, then revisit them whenever a row or column gets tighter. Medium puzzles reward disciplined note-taking and careful elimination rather than trial and error.

How to solve medium Killer Sudoku faster
