16x16 Sudoku: a guide for your next round
Read the aim of 16x16 Sudoku, then make your first move. Fill all cells with 1–9 and A–G; do not repeat a symbol in any row, column or region. Keep the game area visible while you use its controls. Check the rule that explains your first action. Look at what changes after your first action.
Practice with a purpose
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. Notice the feedback after each input.
What you need to achieve
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. 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.
How to interact with the game
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. Avoid pressing the same control repeatedly while a move is being processed.
Put the rules into context
On one puzzle in this collection, row 1, column 4 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. Consider the next action carefully.
One detail worth checking
Notes are reminders, not final entries. A full board only counts as complete when it satisfies every rule. Compare the situation with the worked example. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
