The challenge in front of you
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. Return to the instructions when a step is unclear.
The order of play
- 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.
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. On a smaller screen, keep the active part of the board within view. Avoid pressing the same control repeatedly while a move is being processed.
Try this example
On one puzzle in this collection, row 1, column 3 has 4 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 common point of confusion
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.
