Sudoku

• Fill every row, column, and 3×3 box with the digits 1–9 — no repeats.
• Tap a cell, then tap a number (or use your keyboard).
• Toggle Notes for candidates, or tap Hint when stuck.

Start with the digit that already appears most often — scan rows, columns, and boxes for the one spot it can still go. Use Notes to track candidates in tricky cells, then eliminate as clues fall into place.
