Getting started with 16x16 Sudoku
16x16 Sudoku gives you a focused activity to play in your browser. 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. Treat the first round as a chance to learn the controls. Check the relevant rule before repeating a move.
Something to practise
Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention. Keep the objective visible.
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 playing sequence
- 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.
Getting comfortable with 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. A new-round button replaces the current round.
Put the rules into context
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.
A common point of confusion
Notes are reminders, not final entries. A full board only counts as complete when it satisfies every rule. Check the rule before repeating the action. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
