16x16 Sudoku: learn through an example
Take a moment with 16x16 Sudoku before moving to another game. 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. Identify the playing area and the controls you need. Keep the game area visible while you use its controls.
Practice beyond the first move
Keep the stated aim separate from side details such as animation or appearance. Progress is measured by the game’s own completion or scoring rules. Refer to the controls when needed.
The goal to keep in mind
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. Keep the controls in easy reach.
The steps to play
- 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.
Making selections and moves
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. Check any mode label before starting.
An example before you play
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. Apply the same reasoning to the position in your own round. Choose a deliberate next step.
Notice this detail
Notes are reminders, not final entries. A full board only counts as complete when it satisfies every rule. A different version of the game may use a different rule. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
