A **candidate value**, usually called simply a **candidate**, represents a digit that can be placed into an unsolved cell. Another word used is **possibility**.

Players often use pencilmarks to write the remaining candidates in the grid. Sudoku computer programs also provide markup tools to show the remaining candidates.

When a solving technique proves that a candidate is no longer valid, this candidate is subsequently eliminated. When a Sudoku is completely solved, all candidates are either eliminated or placed in their respective cells.
