30-second primer

Sudoku rules in 30 seconds

Fill every empty cell so each unit contains the digits 1–9 exactly once.

①One clear goal

Complete the board using digits 1–9. The starting clues never change.

↔Every row

Use each digit once—never repeat a number in the same row.

↕Every column

Each column also contains 1–9 exactly once.

▦Every 3×3 box

The nine smaller boxes follow the same no-repeat rule.

✎

Notes are possibilitiesPencil in candidates when you are unsure. A solved cell keeps only its final digit.
