Your objective
Fill all cells with 1–4; do not repeat a symbol in any row, column or region. Keep that objective in view throughout the round. Follow this game’s rules rather than another version’s.
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.
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. Avoid pressing the same control repeatedly while a move is being processed.
Learn from a sample situation
On one puzzle in this collection, row 1, column 3 has 3 in its solution. Read the clues on your current board before using that value; another puzzle can need a different entry. Focus on why the action is allowed, not only its outcome. Verify the rule before continuing.
A useful caution
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. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
