Your guide to 16x16 Sudoku
Bring your attention to one round of 16x16 Sudoku. 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. Choose a comfortable screen position before beginning. Look at what changes after your first action.
A small practice goal
Read one step at a time and try it on the playing area. Match the instruction to the control you use. Notice the feedback after each input.
Understand the aim
Fill all cells with 1–9 and A–G; do not repeat a symbol in any row, column or region. Keep that objective in view throughout the round. Notice how the game responds to your input.
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.
Getting comfortable with 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. On a smaller screen, keep the active part of the board within view. Contact us with the game and device if a control does not respond.
See the idea in action
On one puzzle in this collection, row 1, column 2 has 9 in its solution. Read the clues on your current board before using that value; another puzzle can need a different entry. Focus on why the action is allowed, not only its outcome. Consider the next action carefully.
A useful caution
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. After a move, check what changed. Decide which rule explains the new state before acting again.
