How to play 4x4 Sudoku
Make 4x4 Sudoku your next activity in the game library. Fill all cells with 1–4; do not repeat a symbol in any row, column or region. Keep the game area visible while you use its controls. Choose a comfortable screen position before beginning. Look at what changes after your first action.
Build a steady rhythm
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. Notice the feedback after each input.
Your goal
Fill all cells with 1–4; do not repeat a symbol in any row, column or region. An attractive position is not enough unless the goal is met. Return to the instructions when a step is unclear.
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. On a smaller screen, keep the active part of the board within view. Make sure you are interacting with the game rather than the surrounding page.
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. Read the feedback to see why an action did not have the expected result. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
