How to play 16x16 Sudoku
Make 16x16 Sudoku your next activity in the game library. Fill all cells with 1–9 and A–G; do not repeat a symbol in any row, column or region. Keep the game area visible while you use its controls. Begin with the solo mode shown on the page. Look at what changes after your first action.
Try a deliberate move
After a move, check what changed. Decide which rule explains the new state before acting again. Use the example to check your reasoning.
Your goal
Fill all cells with 1–9 and A–G; do not repeat a symbol in any row, column or region. Read that aim before choosing your first action. Follow this game’s rules rather than another version’s.
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.
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. Read a button’s label before selecting it. Make sure you are interacting with the game rather than the surrounding page.
A useful example
On one puzzle in this collection, row 1, column 4 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. Read the matching step again.
Watch out for this
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. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
