An introduction to playing 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. Check the rule that explains your first action. Look at what changes after your first action.
A small practice goal
Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round. Keep the objective visible.
What you are aiming for
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.
From the start of a round
- 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.
Your inputs
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. Return to the rules if the result is unexpected.
Work through an 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. Your next round may have a different position, so inspect it before acting. Read the matching step again.
Where a round can go wrong
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. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
