Making your first moves in 4x4 Sudoku
Start 4x4 Sudoku by looking at the playing area and its controls. Fill all cells with 1–4; do not repeat a symbol in any row, column or region. Choose a clear next step rather than rushing through the instructions. Keep the instructions close while learning this activity. Use the example below to understand a decision.
Give this approach a try
When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round. Refer to the controls when needed.
Aim for this result
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. Return to the instructions when a step is unclear.
Work through the instructions
- 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.
Your inputs
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. Keep the playing area visible while using these controls. Read the example below alongside these instructions.
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.
A common point of confusion
Notes are reminders, not final entries. A full board only counts as complete when it satisfies every rule. Take a moment to reassess the position before continuing. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
