Follow the steps for 4x4 Sudoku
4x4 Sudoku gives you a focused activity to play in your browser. Fill all cells with 1–4; do not repeat a symbol in any row, column or region.

One thing to notice as you play

What the game asks you to do
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. Return to the instructions when a step is unclear.
Follow these playing steps
- 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. Keep the playing area visible while using these controls. Contact us with the game and device if a control does not respond.
A closer look at one example
On one puzzle in this collection, row 1, column 1 has 4 in its solution. Read the clues on your current board before using that value; another puzzle can need a different entry. Focus on why the action is allowed, not only its outcome. Consider the next action carefully.
A mistake to avoid
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.
