Fireworks

The Fireworks technique identifies a pattern where three candidates in a row, column, and box intersection create mutual constraints that lead to eliminations.

Pattern Recognition

A Fireworks pattern involves:

• A cell at the intersection of a row, column, and box
• Three instances of a candidate that "radiate" from this intersection
• Specific arrangements that force eliminations in related cells

How It Works

The Fireworks pattern creates constraints based on how candidates must be distributed across the intersecting units. If the pattern cells must contain certain digits, candidates in cells that see all pattern cells can be eliminated.
