Find your footing in 16x16 Sudoku
Start 16x16 Sudoku by looking at the playing area and its controls. 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. Choose a clear next step rather than rushing through the instructions.
Give this approach a try
Read one step at a time and try it on the playing area. Match the instruction to the control you use. Make the next step deliberately.
Understand the aim
Fill all cells with 1–9 and A–G; do not repeat a symbol in any row, column or region. Read that aim before choosing your first action. 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.
Controls
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. Use the control method described here for this activity. Read the example below alongside these instructions.
One way to understand the rules
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. Use the example as a guide rather than a substitute for reading your board. Read the matching step again.
An important reminder
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. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
