How to play Killer Sudoku
Start Killer Sudoku by looking at the playing area and its controls. Fill rows, columns and boxes with 1–9 once. Cage digits cannot repeat and must add to their clue. Check the relevant rule before repeating a move. Check the rule that explains your first action. Choose a clear next step rather than rushing through the instructions.

Read before acting
Read one step at a time and try it on the playing area. Match the instruction to the control you use. Notice the feedback after each input.
Your goal

Controls
Click or tap cells and the digit pad. Use Notes, Undo and Reveal selected. Large boards scroll inside the game. Read a button’s label before selecting it. Look at the feedback after the action.
A useful example
A two-cell cage labelled 3 holds 1 and 2; a one-cell cage fixes its own value. Your next round may have a different position, so inspect it before acting. Look for the relevant detail.
Watch out for this
A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. A different version of the game may use a different rule. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
