Single-digit

A single-digit technique only examines the candidate pattern for a single digit.

All singles, Locked Candidates and fish belong to this category.

Many players consider single-digit techniques easier than techniques which use multiple digits. When a computer program is used, it can often highlight the cells which contain candidates for a specific digit. Patterns are much easier to spot in the highlighed cells. When solving a Sudoku on paper, the player may find it more difficult to recognize patterns for a single digit in the pencilmarked grid.
