Practice with a purpose
Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Use the example to check your reasoning.
What the game asks you to do
Fill all cells with 1–4; do not repeat a symbol in any row, column or region. Read that aim before choosing your first action. Notice how the game responds to your input.
Step by step
- 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.
Keyboard and screen 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. Use the visible help when you are unsure of the next input.
Learn from a sample situation
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. Compare this with the rule that governs the move. Notice the change in the playing area.
Check this before moving on
Notes are reminders, not final entries. A full board only counts as complete when it satisfies every rule. A different version of the game may use a different rule. 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.
