The example illustrates the helper; it is not a publisher's daily puzzle.

How the Mini Sudoku helper works

Find justified moves and inspect how the entered constraints force each one. Work from the information you have already revealed; this helper does not fetch an official daily answer.

Results use the puzzle you enter; they are not verified daily answers. Your entries stay out of public URLs.

Original worked example

The first row already contains 2, 3, 4, 5 and 6, so its empty cell is 1. The tool also verifies the column and box, rather than treating a row-only observation as a complete solution.

Separate a deduction from a possible completion

The helper checks the whole entered state. When enumeration completes, a move is reported as forced only if every valid completion agrees. If the bound is reached, possible completions remain available but no forced move is asserted.

Use the reason before opening the solution

Each move has its own explanation grounded in your rows, cells, clues or markers. Inspect one explanation, apply it in the original game and rerun. The full arrangement is in a separate closed section.
