How to play 16x16 Sudoku
Open 16x16 Sudoku, check the instructions and begin a round. 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. Read the objective before making your first input. Check the relevant rule before repeating a move.
Keep the aim in sight
Keep the stated aim separate from side details such as animation or appearance. Progress is measured by the game’s own completion or scoring rules. Refer to the controls when needed.
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. Return to the instructions when a step is unclear.
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. A careful first action helps you become familiar with the layout. Look at the feedback after the action.
A useful 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.
Watch out for this
Notes are reminders, not final entries. A full board only counts as complete when it satisfies every rule. A different version of the game may use a different rule. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
