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. Make the next step deliberately.
Your objective
Fill all cells with 1–4; do not repeat a symbol in any row, column or region. The feedback beside the game helps you follow the round. 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.
The controls to know
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. Avoid pressing the same control repeatedly while a move is being processed.
Follow the example
Before filling a cell, compare the symbols already used in its row, column and 2 × 2 region. A candidate must be absent from all three. Apply the same reasoning to the position in your own round. Take a moment to compare.
A mistake to avoid
Notes are reminders, not final entries. A full board only counts as complete when it satisfies every rule. Take a moment to reassess the position before continuing. 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.
