How to play 4x4 Sudoku
Read the aim of 4x4 Sudoku, then make your first move. Fill all cells with 1–4; do not repeat a symbol in any row, column or region. Use the example below to understand a decision. Keep the instructions close while learning this activity. Choose a clear next step rather than rushing through the instructions.
A careful first round
Before your first action, say what you are trying to achieve. Then compare the result with the goal. Make the next step deliberately.
Your goal
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. Try to explain the aim in your own words.
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.
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. Read a button’s label before selecting it. Use the visible help when you are unsure of the next input.
A useful example
On one puzzle in this collection, row 1, column 2 has 2 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. Take a moment to compare.
Watch out for this
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.
