THE PLAYBOOK · ZEIZEIWAI
Understand the basics of 16x16 Sudoku
Choose a round of 16x16 Sudoku and settle into its rules. 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. Keep the instructions close while learning this activity. Look at what changes after your first action.
Practice beyond the first move
After a move, check what changed. Decide which rule explains the new state before acting again. Make the next step deliberately.
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. The feedback beside the game helps you follow the round. Return to the instructions when a step is unclear.
The order of 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.
Your inputs
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. Check any mode label before starting.
Try this example
On one puzzle in this collection, row 1, column 1 has 3 in its solution. Read the clues on your current board before using that value; another puzzle can need a different entry. Apply the same reasoning to the position in your own round. Check the stated objective.
Pay attention to this rule
Notes are reminders, not final entries. A full board only counts as complete when it satisfies every rule. Take a moment to reassess the position before continuing. 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.
