How to evolve Eevee has proven to be one of the bigger talking points in Pokémon Go so far.
In the classic Pokémon games, Eevee can evolve into different typing varieties based on the use of special items, its happiness level, moves it has available and even the time of day.
With the addition of Candy in Pokémon Go, the way you evolve Pokémon is much simpler, and as such, you cannot use the tried-and-tested method of using one of three elemental stones to turn Eevee into Flareon, Jolteon and Vaporeon. (Some are better than others depending on the situation - find out which you should get first with our Best Pokémon in Pokémon Go page, and our Pokémon Go Type Chart for their relative strengths and weaknesses.)
Once you have caught enough Eevees to evolve one - our pages on finding Pokemon by location, finding which Pokemon hatch from which eggs and locating Pokémon nests near you can help - a neat trick discovered by fans of the game on Reddit will get you the evolution you need.
How to evolve Eevee into evolutions Umbreon, Espeon, Vaporeon, Flareon and Jolteon
If you choose to evolve Eevee without any meddling - by feeding it 25 Eevee candy - then it'll turn to one of the below five types at random. However, users have discovered a trick that allows you to target any of Espeon, Umbreon, Flareon, Jolteon or Vaporeon, by renaming it in one of the following ways:
- Rename as Sakura to evolve into Psychic-type Espeon
- Rename as Tamao to evolve into Dark-type Umbreon
- Rename as Rainer to evolve into water type Vaporeon
- Rename as Sparky to evolve into lightning type Jolteon
- Rename as Pyro to evolve into fire type Flareon
Note the trick works only once per evolution type, so make sure you choose Eevees with the best CP values before you evolve them into the type you want.
Newcomers Umbreon and Espeon are also believed to have a second evolution method, and that's through the Buddy System, according to Reddit. By walking either one 10km, and then evolving it during night or day respectively, it'll turn into the desired evolution.
Since the naming trick only works once per evolution type, this appears to be a useful way to get a second Espeon or Umbreon with some reliability.
What you need to know about Eevee Evolution names in Pokémon Go
Why Sakura, Tamao, Sparky, Rainer and Pyro? The original three are the names of the Eevee brothers from the Pokémon television show, who meet with Ash and the gang in episode 40 to show off their respective Eevee evolutions, with Sakura and Tamao appearing later on in the series.
Once you have called your Eevee into one of the above names, you should quit and reload the app to double check the name change has taken place, which is important considering the servers can lean to be on the unreliable side.
Once you've double checked the new name is indeed in place, then evolve the Eevee as you would any other Pokémon by feeding it Candy, and it should take the form of your chosen type.

Note that while plenty of users have had success with this method - and that it's been confirmed by developer Niantic itself at this year's San Diego Comic Con - there are a handful of cases where it hasn't worked every time. Some say the trick will only work on the first time you evolve the creature, while others might have caught fowl of server issues not renaming their successfully first time, so be sure to check before you try.

How do you evolve Eevee into Leafeon, Glaceon and Sylveon in Pokémon Go?
If you want to get your hands on one of Eevee's many other evolution in Pokémon Go, you can't just yet.
Pokémon Go has added 80 new Johto Pokémon, but that's still only Gen 1 and Gen 2 - in other words, the original creatures from Red, Blue, Yellow, Gold, Silver, and Crystal - which means Eevee can only evolve into Umbreon, Espeon, Flareon, Jolteon and Vaporeon for now.
It'll be interesting to see how game expands to cover more creatures in time, and if so, if there are any tricks required to access these other types.
