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. Look at what changes after your first action. Make your first input carefully and watch the result. Use the example below to understand a decision.
An idea for your next attempt
Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Notice the feedback after each input.
Your objective
Fill all cells with 1–4; do not repeat a symbol in any row, column or region. Read that aim before choosing your first action. Start with a deliberate move.
Work through the instructions
- 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 to interact with the game
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.
A useful 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. Check the stated objective.
Where a round can go wrong
Notes are reminders, not final entries. A full board only counts as complete when it satisfies every rule. Compare the situation with the worked example. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
