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.

One thing to notice as you play

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.

The goal to keep in mind

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. Check the rules when you are unsure.

The order of play

  1. Select an editable cell.
  2. Enter a value using the keypad or keyboard; Notes stores candidates.
  3. Read the region, cage, arrow or outside clues alongside the normal constraints.
  4. Check entries verifies the completed board; Undo reverses your last input.
  5. New puzzle selects another included puzzle.

Keyboard and screen controls

Click or tap cells and the digit pad. Use Notes, Undo and Reveal selected. Large boards scroll inside the game. Use the control method described here for this activity. Make sure you are interacting with the game rather than the surrounding page.

Put the rules into context

A two-cell cage labelled 3 holds 1 and 2; a one-cell cage fixes its own value. Use the example as a guide rather than a substitute for reading your board. Read the matching step again.

Where a round can go wrong

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. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
