Seed Searcher by Lean

This tool allows you to recover the seed of a den in Pokémon Sword and Shield. All you need to do is to input IVs, Nature, Ability, and Characteristic of up to 4 Pokémon.

Step 0 – Frame Advancements

Please read The Advancement and get familiar with how to advance frames.

Step 1 – Catching the first Pokémon

A – Access to 1 and 2 Star dens

In this case you do not need to advance any frames at the beginning. Simply catch a Pokémon in the den you want to check, calculate IVs, and enter everything in the tool. Click “Check IV”. If you get “Not enough info.”, then you need to catch a Pokémon from the second dropdown and enter the IVs.

Note: This does not work with all IV combinations.

B – Access to 3 to 5 star dens

Here, you start by advancing by 3 days. Then you need to catch a Pokémon with less than 4 fixed IVs (most 2-4 star dens). After entering all information the tool either tells you that you need to catch another Pokémon with more fixed IVs from this frame, or that this Pokémon does not provide enough information. In this case repeat the process, but advance the day by one more than before.

Step 2 – Catch 2 more Pokémon

Repeat the process, but you can use any Pokémon that is not from the same day as before.

Step 3 – Calculate

Click “Start Search”. This can take a long time, depending on the power of your PC. When a result is found, it will be printed in the textbox.

The UI consists of multiple parts.

Here, the Den and Rarity, or the Nest can be specified for the search. Den and Rarity uses the game internal listing. If you are more familiar with Nest numbers, i.e. because Serebii uses them, you can use them as well. Further, you can specifiy your game version.

Pokémon Info Day 4

Here, 3 boxes are available. First, only one of them is editable. You need to catch a Pokémon with 1, 2, or 3 fixed IVs (= number of 31 IVs). After entering the information, click on “Check IVs”. This check will calculate the IVs of other Pokémon on this slot with more fixed IVs than the one you entered. You might get a “NOK” as response, this happens either when no Pokémon is available with more IVs or if you used a 3IV Pokémon and the next fixed IV (i.e. the new 31 stat) could not be determined. In this case you need to advance your frame by 1 and try again.

Next, you can enter information about Pokémon with more fixed IVs. You only need to catch one of them and fill one box. The drop down tells you the Pokémon you can use for this. Also, please note that the predicted IVs will match with the Pokémon and you only need to provide data for the red boxes (if any). If the IVs do not match, double check the amount of stars from the raid or the previous input.

Please note, that you will need your exact IVs, no ranges. An IV Calculator will be added in the next version, so for now you have to use an external one.

Pokémon Info Day 5 and 6

This is the same as before, except you can catch any Pokémon here from this day.

Here, your seed will be printed when its found. Click “Start Search” to start a new search. A 6/6 search should not take much time, a 5/6 search can take an hour or two, depending on the IV Deviation of your seed. 4/6 will take multiple hours per deviation, so only use it if nothing else is possible.

“New Search” will reset the form and allow you to start a new search.

“Show Results” will be enabled after a seed has been found. This opens a window where you can get more information about your seed, such as find Pokémon with specific IVs, nature, or even shinyness.

“Calculations” describes a number about your seed. At the beginning, when the IVs for your Pokémon are generated by the game, RNG might do additional calls, shifting the target sequence back in line. On average, a 2IV Pokémon has a Calculation of 0.66, which means that every third Pokémon has a Calculation of more than 0, while 2 out of 3 Pokémon have a Calculation of 0. Please note that this is an average value. There are some rare cases, where your Calculation is 6 or higher. The default value of 0-3 should handle most cases. If you cannot find your seed and your PC is fast enough, you can search with a higher Calculation value. If not, it is advised to advance the frame and start over.

What does “4/6”, “5/6”, or “6/6” mean?

The RNG used for raids produces a sequence of random numbers. In order to get the seed from a list of Pokémon part of the random number sequence is restored. The IVs you provide for your Day 4 Pokémon belongs to this sequence of random numbers. To get the seed as fast as possible, an IV spread that allows to reconstruct 6 consecutive random numbers works the best, which is 6/6. If the IV spread provides less numbers, then the seed finding will take longer.

I get the [CUDAError] CUDA_ERROR_LAUNCH_FAILED error. What should I do?

In this case there is a batch file in the directory CudaSetup called EnableCuda.bat . This needs to be executed as admin in order to write 2 values to the registry. After that, the PC must be rebooted in order for it to take action. For more information about what the registry entries are doing, check out the documentation by Microsoft.

Here are a few points I want to add in future versions:

  • GPU Search – Improves performance drastically, depending on your GPU. CUDA GPUs are supported right now, more GPUs follow.
  • CMD Version – A version where you simply have to use an export as argument and get a calculation starting. This is a useful feature for bots.

Blocked IP Address

Your IP address has been temporarily blocked due to a large number of HTTP requests. The most common causes of this issue are:

  • If you are using Maxthon or Brave as a browser, or have installed the Ghostery add-on, you should know that these programs send extra traffic to our servers for every page on the site that you browse. Using GameFAQs regularly with these browsers can cause temporary and even permanent IP blocks due to these additional requests.
  • Some unofficial phone apps appear to be using GameFAQs as a back-end, but they do not behave like a real web browser does. This triggers our anti-spambot measures, which are designed to stop automated systems from flooding the site with traffic. Continued use of these apps may cause your IP to be blocked indefinitely. There is no official GameFAQs app, and we do not support nor have any contact with the makers of these unofficial apps.
  • Using a script or add-on that scans GameFAQs for box and screen images (such as an emulator front-end), while overloading our search engine
  • Running a “scraper” or “downloader” program that either does not identify itself or uses fake headers to elude detection
  • Using a badly configured (or badly written) browser add-on for blocking content
  • Overusing our search engine with a very large number of searches in a very short amount of time

If you promise to stop (by clicking the Agree button below), we’ll unblock your connection for now, but we will immediately re-block it if we detect additional bad behavior.

If you do not understand what is causing this behavior, please contact us here.
