Find your footing in 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. Check the relevant rule before repeating a move. Keep the instructions close while learning this activity. Use the example below to understand a decision.
Practice with a purpose
After a move, check what changed. Decide which rule explains the new state before acting again. 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. Review the board or playing area as it changes.
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.
How to interact with the game
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. Look at the feedback after the action.
Put the rules into context
Before filling a cell, compare the symbols already used in its row, column and 2 × 2 region. A candidate must be absent from all three. Use the example as a guide rather than a substitute for reading your board. Keep the controls nearby.
A mistake to avoid
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. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
