المتطلب السابق: Finned & Sashimi Fish

Overview

Sashimi Jellyfish is the four-row variant of sashimi fish. A Jellyfish pattern with missing base cells, compensated by fins, allows restricted eliminations.

How It Works

  1. Find an almost-Jellyfish with missing base candidates.
  2. Fin cells in the same block compensate for the gaps.
  3. Eliminate the candidate from cells seeing both the fin block and the cover columns.

Example

Base columns 1, 2, 6 and 8 form a Jellyfish for digit 7 in cover rows 1, 4, 5 and 8.
