Getting started with Killer Sudoku

Open Killer Sudoku, check the instructions and begin a round. Fill rows, columns and boxes with 1–9 once. Cage digits cannot repeat and must add to their clue. Look at what changes after your first action. Begin with the solo mode shown on the page. Keep the game area visible while you use its controls.

This collection contains 8 puzzles. Progress is saved in this browser. The same puzzle can appear again; the collection is not labelled with calibrated difficulty levels.

A focus for your next round

Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round. Make the next step deliberately.

The purpose of your moves

Fill rows, columns and boxes with 1–9 once. Cage digits cannot repeat and must add to their clue. Read that aim before choosing your first action. Notice how the game responds to your input.

  2. Enter a value using the keypad or keyboard; Notes stores candidates.

See the idea in action

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. Check the stated objective.

Avoid this misunderstanding

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. Keep the stated aim separate from side details such as animation or appearance. Progress is measured by the game’s own completion or scoring rules.
