Jellyfish and Squirmbag strategy for solving sudoku
Advanced strategies
Jellyfish (4 arms star formation)
Squirmbag (5 arms star formation)
The principle is exactly the same one as the X-wing (2 arms star formation) and the Swordfish (3 arms star formation).
It is respectively necessary to find a configuration presenting 2 at 4 candidates aligned between them and divided in 4 lines or columns for the Jellyfish, and 2 to 5 candidates in 5 lines or columns for the Squirmbag.
Example
To be honnest, it is only by exhaustiveness that I quote these methods. I did not have the occasion yet to use them and I thus do not have an example allowing to illustrate these methods which hold from my point of view more theory that practice.
