An introduction to playing 16x16 Sudoku
16x16 Sudoku gives you a focused activity to play in your browser. Fill all cells with 1–9 and A–G; do not repeat a symbol in any row, column or region. Choose a clear next step rather than rushing through the instructions. Check the rule that explains your first action. Look at what changes after your first action.
An idea for your next attempt
Before your first action, say what you are trying to achieve. Then compare the result with the goal. Make the next step deliberately.
Aim for this result
Fill all cells with 1–9 and A–G; do not repeat a symbol in any row, column or region. Use the instructions to see which actions move you towards it. Try to explain the aim in your own words.
Follow these playing steps
- 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.
Input guidance
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. A new-round button replaces the current round.
Try this example
On one puzzle in this collection, row 1, column 3 has C in its solution. Read the clues on your current board before using that value; another puzzle can need a different entry. Apply the same reasoning to the position in your own round. Notice the change in the playing area.
A mistake to avoid
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. When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round.
