Follow the steps for 4x4 Sudoku
Open 4x4 Sudoku, check the instructions and begin a round. Fill all cells with 1–4; do not repeat a symbol in any row, column or region. Look at what changes after your first action. Keep the instructions close while learning this activity. Keep the game area visible while you use its controls.
A small practice goal
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. Make the next step deliberately.
What you need to achieve
Fill all cells with 1–4; do not repeat a symbol in any row, column or region. Read that aim before choosing your first action. Follow this game’s rules rather than another version’s.
How a round unfolds
- 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.
Choosing and moving on screen
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. Check any mode label before starting.
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. Apply the same reasoning to the position in your own round. Check the stated objective.
Where a round can go wrong
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.
