6x6 Sudoku: a guide for your next round
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. Use the example below to understand a decision. Check the rule that explains your first action. Look at what changes after your first action.
One thing to notice as you play
Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Keep the objective visible.
Aim for this result
Fill all cells with 1–6; do not repeat a symbol in any row, column or region. An attractive position is not enough unless the goal is met. Return to the instructions when a step is unclear.
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.
The controls to know
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.
One way to understand the rules
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. Your next round may have a different position, so inspect it before acting. Keep the controls nearby.
A mistake to avoid
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. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
