What is a Hidden Single?
A Hidden Single occurs when a number can only fit in one specific cell within a larger region (like a 3x3 block, a row, or a column). It is "hidden" because other numbers could also theoretically fit in that cell, but the cell is the ONLY one available for THAT specific digit in that region.
The Secret to Speed: Cross-Hatching
The fastest way to find Hidden Singles is cross-hatching. By looking at a digit and ruled-out rows/columns, you quickly "rule in" the only possible spot left in a 3x3 block. This approach is the heart of expert grid-vision.
Hidden Single FAQ
What is a Hidden Single in Sudoku?
A Hidden Single happens when a specific number can only fit in one exact cell within a particular row, column, or 3x3 block—even if that cell could theoretically hold other numbers. It is "hidden" because you find it by looking at the region (scanning), not just the cell.
Is this a beginner technique?
Yes. Hidden Single (found via cross-hatching) is the most common way people solve basic Sudoku puzzles. Master it, and you can solve almost any Easy or Medium puzzle on paper.
What is cross-hatching?
Cross-hatching is the process of scanning rows and columns to "rule out" cells in a 3x3 block. If ruling out cells leaves only one spot for a number, that is a Hidden Single.
Why practice this specifically?
Building raw scanning speed is what separates intermediate and expert solvers. These targeted worksheets force you to improve your grid-vision by putting you in positions where Hidden Singles are the primary way forward.
Are these PDFs suitable for groups?
Yes! The 4-per-page format is perfect for community groups, Sudoku clubs, and senior centers where you want a standard, easy-to-read handout.
