Your objective
Fill all cells with 1–9 and A–G; do not repeat a symbol in any row, column or region. Use the instructions to see which actions move you towards it. Start with a deliberate move.
How to proceed
- 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.
Getting comfortable with the controls
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. Use the control method described here for this activity. A new-round button replaces the current round.
One way to understand the rules
On one puzzle in this collection, row 1, column 3 has 2 in its solution. Read the clues on your current board before using that value; another puzzle can need a different entry. Use the example as a guide rather than a substitute for reading your board. Choose a deliberate next step.
A useful caution
Notes are reminders, not final entries. A full board only counts as complete when it satisfies every rule. Check the rule before repeating the action. 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.
