A practical guide to 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. Use the example below to understand a decision. Identify the playing area and the controls you need. Choose a clear next step rather than rushing through the instructions.
Build familiarity through play
Before your first action, say what you are trying to achieve. Then compare the result with the goal. Make the next step deliberately.
The purpose of your moves
Fill all cells with 1–9 and A–G; do not repeat a symbol in any row, column or region. Keep that objective in view throughout the round. Follow this game’s rules rather than another version’s.
Start here and follow along
- 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.
Input guidance
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. Read the example below alongside these instructions.
A closer look at one example
On one puzzle in this collection, row 1, column 2 has 9 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. Notice the change in the playing area.
A mistake to avoid
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.
