Not working on 1.1.3
What a pity...

For me it worked (Version 1.1.3). 🥳

I had 4 recommended tiles and I planned on trying every tile at least 3 times. I was successful on the 3rd try at the first tile already.

There is an old and a new version of the calculator. I used this one:
https://lincoln-lm.github.io/JS-Finder/Tools/BDSPFeebas.html

@TimHe95
With the 1.1.3 update there is a new version of this same calculator tool. But instead of just providing one Lotto ID number, the new tool requires at least 2 days-worth of Lotto IDs and Swarm info (which route there appears to be a lot of a specific Pokémon for a given day—you can find this by opening your menu and checking the ‘current objective’) in order to help narrow down your exact game seed…and thus accurately determine the four tiles that spawn Feebas on a given day.

What are the sold sphere/Drill sphere checks about and where can I find that info?

Does this work on the Nintendo DS version?
