Know the goal in 4x4 Sudoku
4x4 Sudoku gives you a focused activity to play in your browser. 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.
Something to practise
Before your first action, say what you are trying to achieve. Then compare the result with the goal. Use the example to check your reasoning.
What you are aiming for
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.
How to proceed
- 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 your actions work
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. Use the visible help when you are unsure of the next input.
See the idea in action
On one puzzle in this collection, row 1, column 3 has 4 in its solution. Read the clues on your current board before using that value; another puzzle can need a different entry. Compare this with the rule that governs the move. Consider the next action carefully.
Watch out for this
Notes are reminders, not final entries. A full board only counts as complete when it satisfies every rule. Compare the situation with the worked example. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
