Give this approach a try
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. Refer to the controls when needed.
What counts as success
Fill all cells with 1–9; 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.
Making your moves
- 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.
How to use 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. A careful first action helps you become familiar with the layout. Read the example below alongside these instructions.
See how the rules apply
Before filling a cell, compare the symbols already used in its row, column and 3 × 3 region. A candidate must be absent from all three. Use the example as a guide rather than a substitute for reading your board. Notice the change in the playing area.
A mistake to avoid
Notes are reminders, not final entries. A full board only counts as complete when it satisfies every rule. Compare the situation with the worked example. 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.
