What you need to achieve
Fill all cells with 1–6; do not repeat a symbol in any row, column or region. Use the instructions to see which actions move you towards it. Check the rules when you are unsure.
Follow these playing steps
- Select an empty cell. The original clues cannot be edited.
- Choose a symbol from the number pad, or type it on a keyboard.
- Turn Notes on to record candidate symbols without committing an answer.
- Use Check entries to check your filled values. Hint reveals one value from the verified solution.
- Complete the board, or choose New puzzle for another board.
Input guidance
Tap or click a cell and use the number pad. Keyboard: arrows select cells; digits (and A–G on 16×16) enter values; Backspace erases. Keep the playing area visible while using these controls. Read the example below alongside these instructions.
An example to follow
Before filling a cell, compare the symbols already used in its row, column and 2 × 3 region. A candidate must be absent from all three. Apply the same reasoning to the position in your own round. Keep the game’s format in mind.
Avoid this misunderstanding
Notes are reminders, not final entries. A full board only counts as complete when it satisfies every rule. 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.
