Understand the basics of 4x4 Sudoku
Use a short break to learn the rhythm of 4x4 Sudoku. Fill all cells with 1–4; do not repeat a symbol in any row, column or region. Use the example below to understand a decision. Keep the instructions close while learning this activity. Check the relevant rule before repeating a move.
Practice with a purpose
Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart. Refer to the controls when needed.
Understand the aim
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. Try to explain the aim in your own words.
From the start of a round
- 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.
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. Look at the feedback after the action.
An example to follow
On one puzzle in this collection, row 1, column 1 has 4 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. Keep the game’s format in mind.
A mistake to avoid
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. 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.
