Medium Killer Sudoku Strategies
Here's how to tackle medium difficulty killer sudoku:
Systematically Analyze Cage Combinations With larger cages, you'll need to methodically work through all possible number combinations. List them out, then consider which digits can actually appear together based on sudoku constraints. This systematic approach helps you spot the right combination.
Use the 45 Rule Remember that the digits 1 through 9 always sum to 45. If you know some cage sums in a row, column, or box, you can work backwards to figure out what the remaining cells must sum to. This is a powerful technique for medium puzzles.
Watch How Cages Interact Cages don't exist in isolation. When you place a number in one cage, it affects what's possible in overlapping or adjacent cages. Learning to track these relationships creates chains of deductions that make solving much easier.
