How to play 4x4 Sudoku
Try 4x4 Sudoku at your own pace and keep its objective in view. 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.
Try a deliberate move
After a move, check what changed. Decide which rule explains the new state before acting again. Make the next step deliberately.
Your goal
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. Take a moment to understand the current position.
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. A careful first action helps you become familiar with the layout. Avoid pressing the same control repeatedly while a move is being processed.
A useful example
On one puzzle in this collection, row 1, column 1 has 1 in its solution. Read the clues on your current board before using that value; another puzzle can need a different entry. Your next round may have a different position, so inspect it before acting. 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. A different version of the game may use a different rule. Keep the stated aim separate from side details such as animation or appearance. Progress is measured by the game’s own completion or scoring rules.
