Killer Sudoku: learn through an example
Killer Sudoku gives you a focused activity to play in your browser. 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.

A closer look at one 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. Verify the rule before continuing.
Avoid this misunderstanding
A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. Read the feedback to see why an action did not have the expected result. When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round.
