The Franken Jellyfish is a fish pattern of the Franken Fish type. This type allows either the defining set or the secondary set to contain boxes, as well as lines.
Franken Jellyfish rrrb-cccc
This is a fish diagram of a Franken Jellyfish with a defining set of 3 rows with 1 box and a secondary set of 4 columns.
- Rotate this diagram 90 degrees for a Franken Jellyfish cccb-rrrr.
- Swap '/' with 'e' for a Franken Jellyfish cccc-rrrb.
- Rotate it 90 degrees for a Franken Jellyfish rrrr-cccb.
Franken Jellyfish rrbb-cccc
Here we see a Franken Jellyfish with a defining set of 2 rows with 2 boxes and a secondary set of 4 columns.
In this example, the defining set contains rows 1 & 5 and boxes 7 & 8. The secondary set contains columns 1, 2, 4 & 5. All the candidates in the defining set (marked with n) are located inside the secondary set. The remaining candidates from these 4 columns can be eliminated.
Configurations Which Look Like Franken Jellyfish but Are Not
This configuration using 2 rows in the same floor dissolves into 3 Locked Candidates steps.
- Solving path
- Locked Candidates 1 in box 3 + row 3: eliminate remaining candidates in row 3.
- Locked Candidates 2 in box 1 + 7 with columns 1 + 2: eliminate candidates in box 4 for columns 1 + 2.
- Locked Candidates 2 in box 2 + 8 with columns 4 + 5: eliminate candidates in box 5 for columns 4 + 5.
This configuration using 2 non-aligned boxes also dissolves into 3 Locked Candidates steps.
- Solving path
- Locked Candidates 1 in box 3 + row 3: eliminate remaining candidates in row 3.
- Locked Candidates 2 in box 1 + 3 with columns 1 + 2: eliminate candidates in box 4 for columns 1 + 2.
- Locked Candidates 2 in box 2 + 5 with columns 4 + 5: eliminate candidates in box 8 for columns 4 + 5.
A configuration with 2 boxes sharing the same 2 columns (swap boxes 4 and 5 in the diagram above) would not work, because locked candidates in box 3 + row 3 would eliminate the last candidate from column 3, leaving the puzzle unsolvable.
