❓ Frequently Asked Questions
What defines an intermediate Sudoku puzzle?
It typically requires more than basic singles and uses techniques such as naked pairs, hidden pairs, pointing pairs, and box-line reductions.
What is a naked pair?
A set of two cells in a unit that can only contain the same two candidates, allowing those candidates to be eliminated from other cells in the unit.
What is a hidden pair?
A pair of digits that only appear in the same two cells within a unit, even if those cells show additional candidates; keep only those two digits in those cells.
How should I use pencil marks when solving?
Write possible numbers in small in each cell to track candidates, then update as you apply techniques to reveal eliminations and progress.
