Classic Sudoku: a guide for your next round

A small practice goal
Read one step at a time and try it on the playing area. Match the instruction to the control you use. Use the example to check your reasoning.
What counts as success
Fill all cells with 1–9; do not repeat a symbol in any row, column or region. Use the instructions to see which actions move you towards it. Return to the instructions when a step is unclear.
How to proceed
- 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.
Choosing and moving on screen
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. Look at the feedback after the action.
Work through an example
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. Keep the controls nearby.
Keep this in mind
Notes are reminders, not final entries. A full board only counts as complete when it satisfies every rule. Compare the situation with the worked example. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
