The 16x16 Sudoku playbook
Make 16x16 Sudoku your next activity in the game library. Fill all cells with 1–9 and A–G; do not repeat a symbol in any row, column or region. Use the example below to understand a decision. Identify the playing area and the controls you need. Choose a clear next step rather than rushing through the instructions.
Practice beyond the first move
Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow. Make the next step deliberately.
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. Use the instructions to see which actions move you towards it. The example below illustrates a decision.
From the start of a round
- 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. Keep the playing area visible while using these controls. A new-round button replaces the current round.
Learn from a sample situation
On one puzzle in this collection, row 1, column 3 has 2 in its solution. Read the clues on your current board before using that value; another puzzle can need a different entry. Compare this with the rule that governs the move. Keep the controls nearby.
Notice this detail
Notes are reminders, not final entries. A full board only counts as complete when it satisfies every rule. Read the feedback to see why an action did not have the expected result. 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.
