Learn the rules of 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. Keep the game area visible while you use its controls. Keep the instructions close while learning this activity. Check the relevant rule before repeating a move.

Give this approach a try

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.

What you need to achieve

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. Notice how the game responds to your input.

How a round unfolds

  1. Select an empty cell. The original clues cannot be edited.
  2. Choose a symbol from the number pad, or type it on a keyboard.
  3. Turn Notes on to record candidate symbols without committing an answer.
  4. Use Check entries to check your filled values. Hint reveals one value from the verified solution.
  5. Complete the board, or choose New puzzle for another board.

Making selections and moves

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 one clear input at a time.

A closer look at one example

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. Compare this with the rule that governs the move. Read the matching step again.

Avoid this misunderstanding

Notes are reminders, not final entries. A full board only counts as complete when it satisfies every rule. Check the rule before repeating the action. After a move, check what changed. Decide which rule explains the new state before acting again.
