How to play 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. Make your first input carefully and watch the result. Keep the game area visible while you use its controls.
Keep the aim in sight
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. Make the next step deliberately.
Your goal
Fill all cells with 1–4; do not repeat a symbol in any row, column or region. An attractive position is not enough unless the goal is met. Return to the instructions when a step is unclear.
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. On a smaller screen, keep the active part of the board within view. Read the example below alongside these instructions.
A useful example
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. Your next round may have a different position, so inspect it before acting. Check the stated objective.
Watch out for this
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.
