1. How to Start with Killer Sudoku
When beginning Killer Sudoku, familiarize yourself with the grid structure. Each “cage” indicates a sum, and no number may repeat within a cage. Start by filling in cages with only one possible combination, then proceed to intersecting cages. This step-by-step approach helps reduce errors and increases your efficiency.
