Use a short break to learn the rhythm of 16x16 Sudoku. Fill all cells with 1–9 and A–G; do not repeat a symbol in any row, column or region. Choose a clear next step rather than rushing through the instructions. Identify the playing area and the controls you need. Keep the game area visible while you use its controls.
Build familiarity through play
When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round. Use the example to check your reasoning.
The challenge in front of you
Fill all cells with 1–9 and A–G; do not repeat a symbol in any row, column or region. An attractive position is not enough unless the goal is met. Keep the controls in easy reach.
How a round unfolds
- 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. A careful first action helps you become familiar with the layout. Use the visible help when you are unsure of the next input.
An example to follow
On one puzzle in this collection, row 1, column 3 has C in its solution. Read the clues on your current board before using that value; another puzzle can need a different entry. Focus on why the action is allowed, not only its outcome. Keep the controls nearby.
A mistake to avoid
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. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
