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. Keep the game area visible while you use its controls. Check the rule that explains your first action. Look at what changes after your first action.
One thing to notice as you play
Before your first action, say what you are trying to achieve. Then compare the result with the goal. Use the example to check your reasoning.
Aim for this result
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. Follow this game’s rules rather than another version’s.
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. A careful first action helps you become familiar with the layout. Use one clear input at a time.
See how the rules apply
On one puzzle in this collection, row 1, column 2 has 2 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. Look for the relevant detail.
A mistake to avoid
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. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
