6x6 Sudoku: rules and examples
Use a short break to learn the rhythm of 6x6 Sudoku. Fill all cells with 1–6; do not repeat a symbol in any row, column or region. Look at what changes after your first action. Check the rule that explains your first action. Choose a clear next step rather than rushing through the instructions.
A focus for your next round
Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention. Make the next step deliberately.
What the game asks you to do
Fill all cells with 1–6; do not repeat a symbol in any row, column or region. Read that aim before choosing your first action. Review the board or playing area as it changes.
Step by step
- 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 use the controls
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. Use the visible help when you are unsure of the next input.
Learn from a sample situation
On one puzzle in this collection, row 1, column 1 has 4 in its solution. Read the clues on your current board before using that value; another puzzle can need a different entry. Use the example as a guide rather than a substitute for reading your board. Choose a deliberate next step.
Watch out for this
Notes are reminders, not final entries. A full board only counts as complete when it satisfies every rule. Check the rule before repeating the action. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
