In Pokémon Go, Eevee is able to evolve into three different elemental Pokémon. In the Nintendo games, Eevee is evolved with the use of precious stones. Thing is, these stones do not yet exist in Pokémon Go, so no one really knows how to guarantee which evolution to get when evolving Eevee. Not until now, that is.

Redditor by the name of smithnigel, over at the Pokemon Go Subreddit, seems to have figured out an almost sure way of evolving your Eevee into the evolution that you want. The secret, as it turns out, is hidden in the long running anime.

In the anime, Ash encountered three Pokémon Trainer brothers with wildly different personalities. Named Rainer, Sparky and Pyro, these three brothers each had an evolved Eevee that fit their personalities: Vaporeon, Jolteon, and Flareon, respectively.

After a lot of trial and error by smithnigelwho tried a number of old and now-debunked theories of how Eevee’s evolution works in Nintendo and Niantic’s latest mobile craze, it seems that a viable solution has been found!

The answer, as it turns out, is really simple. All a Pokémon Go gamer has to do is to name the Eevee to be evolved after one of the Pokémon trainer brothers.

Name your Eevee Rainer for a Vaporeon, Sparky for a Jolteon, or Pyro for a Flareon. Once you have named your Eevee, just restart the game to ensure the name has stuck (this is an important step, as some users who did not restart their games did not get the correct evolution). After this, simply head on over to your now renamed Eevee, click on the big evolve button, and viola! You will now have the Eevee evolution of your choice.

It is worth noting that this trick only seems to work once per named Eevee evolution. For example, if you name your Eevee Pyro, you are only guaranteed of getting a Flareon once by using this method. The same applies for the Vaporeon and Jolteon. Future attempted evolutions using the trainer names will not guarantee their outcomes.

All reports indicate that this method does work, and I know that Hans is vehemently doing his best to capture Eevee for an evolution [Easier said than done – Hans]. Once we manage to catch enough Eevee’s to try this theory out, we will report back.
