4x4 Sudoku: what to know before playing
Bring your attention to one round of 4x4 Sudoku. Fill all cells with 1–4; do not repeat a symbol in any row, column or region. Choose a clear next step rather than rushing through the instructions. Keep the instructions close while learning this activity. Keep the game area visible while you use its controls.
Bring this focus to a round
Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Make the next step deliberately.
The purpose of your moves
Fill all cells with 1–4; do not repeat a symbol in any row, column or region. The feedback beside the game helps you follow the round. Check the rules when you are unsure.
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.
Keyboard and screen 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. Return to the rules if the result is unexpected.
See how the rules apply
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. Choose a deliberate next step.
A common point of confusion
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. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
