16x16 Sudoku: rules and examples
Start 16x16 Sudoku by looking at the playing area and its controls. 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. Choose a clear next step rather than rushing through the instructions.
Give this approach a try
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.
Aim for this result
Fill all cells with 1–9 and A–G; do not repeat a symbol in any row, column or region. The feedback beside the game helps you follow the round. Check the rules when you are unsure.
Step by step
- 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 your actions work
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. Read the example below alongside these instructions.
Follow the example
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. Use the example as a guide rather than a substitute for reading your board. Consider the next action carefully.
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. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
