Know the goal in 4x4 Sudoku
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. Look at what changes after your first action. Keep the instructions close while learning this activity. Choose a clear next step rather than rushing through the instructions.
Build familiarity through play
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. Keep the objective visible.
What you are aiming for
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. Keep the controls in easy reach.
Follow these playing steps
- 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.
The controls to know
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. Use one clear input at a time.
An example before you play
On one puzzle in this collection, row 1, column 2 has 2 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. Take a moment to compare.
Keep this in mind
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. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
