About easy killer sudoku

Easy killer sudoku gives you a head start. You get 20 to 30 digits already placed on the board, and every cage holds just 2 or 3 cells. That means the cage sums are small, and the possible digit combinations are short lists you can work through quickly.

The main technique at this level is cage-sum elimination. A 2-cell cage with a sum of 3 can only be 1+2. A 2-cell cage summing to 17 can only be 8+9. A 3-cell cage summing to 6 is always 1+2+3. These fixed combinations fill in cells immediately, and the givens handle most of the rest.

This is the right place to get comfortable with how cages interact with standard Sudoku rules. When a cage sits inside a single 3x3 box, its digits also can't repeat in that box. When a cage spans two boxes, you're juggling two constraints at once. Practice reading both until it feels automatic. Once easy puzzles take you under 10 minutes, try medium.
