Read this daily Sudoku solution in context

This walkthrough belongs to the date, difficulty and puzzle ID shown above. The original grid provides the starting conditions, and the technique summary reports this actual trace rather than a generic difficulty promise. The sample deduction below is taken from that verified trace.

Follow the replay without changing your save

The interactive replay lets you inspect every before and after state in order. It includes candidate eliminations as well as placements. Reading the replay is separate from playing: it does not enter numbers into your current board or increase completion statistics.
