16x16 Sudoku: rules and examples
Bring your attention to one round of 16x16 Sudoku. Fill all cells with 1–9 and A–G; do not repeat a symbol in any row, column or region. Check the relevant rule before repeating a move. Identify the playing area and the controls you need. Keep the game area visible while you use its controls.
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. Use the example to check your reasoning.
The goal to keep in mind
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. Take a moment to understand the current position.
The order of play
- 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.
Using the playing area
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. Look at the feedback after the action.
Put the rules into context
On one puzzle in this collection, row 1, column 3 has A in its solution. Read the clues on your current board before using that value; another puzzle can need a different entry. Use the example as a guide rather than a substitute for reading your board. Keep the game’s format in mind.
Notice this detail
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. 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.
