Your guide to 4x4 Sudoku
Try 4x4 Sudoku at your own pace and keep its objective in view. Fill all cells with 1–4; do not repeat a symbol in any row, column or region. Look at what changes after your first action. Make your first input carefully and watch the result. Keep the game area visible while you use its controls.
Something to practise
Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Make the next step deliberately.
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. Start with a deliberate move.
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.
How your actions work
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. Check any mode label before starting.
Learn from a sample situation
On one puzzle in this collection, row 1, column 1 has 3 in its solution. Read the clues on your current board before using that value; another puzzle can need a different entry. Apply the same reasoning to the position in your own round. Consider the next action carefully.
Keep this in mind
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. 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.
