4x4 Sudoku: what to know before playing
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. 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.
One thing to notice as you play
When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round. Make the next step deliberately.
The goal to keep in mind
Fill all cells with 1–4; do not repeat a symbol in any row, column or region. Keep that objective in view throughout the round. Check the rules when you are unsure.
The steps to play
- 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. Keep the playing area visible while using these controls. Use one clear input at a time.
Put the rules into context
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. Your next round may have a different position, so inspect it before acting. Read the matching step again.
Watch out for this
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. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
