How to play 16x16 Sudoku
Use a short break to learn the rhythm of 16x16 Sudoku. Fill all cells with 1–9 and A–G; do not repeat a symbol in any row, column or region. Look at what changes after your first action. Identify the playing area and the controls you need. Choose a clear next step rather than rushing through the instructions.
Read before acting
Read one step at a time and try it on the playing area. Match the instruction to the control you use. 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. The feedback beside the game helps you follow the round. Review the board or playing area as it changes.
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. Avoid pressing the same control repeatedly while a move is being processed.
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. Compare this with the rule that governs the move. 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. Take a moment to reassess the position before continuing. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
