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. Keep the game area visible while you use its controls. Identify the playing area and the controls you need. Choose a clear next step rather than rushing through the instructions.
A small practice goal
Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart. Use the example to check your reasoning.
The purpose of your moves
Fill all cells with 1–9 and A–G; do not repeat a symbol in any row, column or region. An attractive position is not enough unless the goal is met. Start with a deliberate move.
Work through the instructions
- 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.
Choosing and moving on screen
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. A new-round button replaces the current round.
Work through an 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.
Keep this in mind
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. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
