Getting started with 16x16 Sudoku
Take a moment with 16x16 Sudoku before moving to another game. 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.
Something to practise
Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention. Make the next step deliberately.
Understand the aim
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. The example below illustrates a decision.
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.
How to use the 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. Keep the playing area visible while using these controls. Return to the rules if the result is unexpected.
An example to follow
Before filling a cell, compare the symbols already used in its row, column and 4 × 4 region. A candidate must be absent from all three. Compare this with the rule that governs the move. Keep the game’s format in mind.
Check this before moving on
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. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
