4x4 Sudoku: a guide for your next round
Choose a round of 4x4 Sudoku and settle into its rules. 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. Keep the instructions close while learning this activity. Use the example below to understand a decision.
Bring this focus to a round
Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention. Notice the feedback after each input.
The purpose of your moves
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. Take a moment to understand the current position.
The playing sequence
- 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.
Making selections and moves
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. Return to the rules if the result is unexpected.
Learn from a sample situation
On one puzzle in this collection, row 1, column 3 has 3 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. Check the stated objective.
Pay attention to this rule
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. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
