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. Check the relevant rule before repeating a move. Identify the playing area and the controls you need. 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. 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. Use the control method described here for this activity. Avoid pressing the same control repeatedly while a move is being processed.
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. Compare this with the rule that governs the move. Consider the next action carefully.
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. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
