So I just caught an Eevee. Now, I need 25 candies to evolve it. The fact is that in the GameBoy color versions, that Pokémon needed a stone to evolve instead of experience. Depending of the stone he was fed with (thunder, water or fire), he was evolving in a different Pokémon.

Is the stone feature also in Pokémon Go? If not, what decide the evolution of this Pokémon?

Bonus point : If it's possible, how can I get a stone?


By default, when you evolve an Eevee in Pokémon GO, the evolution is chosen randomly from the set of potential "eeveelutions". Evolution stones as you know them (water, fire, etc.) don't exist in the current version of Pokémon GO.

Edit: There also seems to be a method for forcing a specific evolution by giving your Eevee a certain nickname before it evolves. See @Brant's answer for more details.

    I sure hope they introduce the evolve at night thing when they introduce Umbreon (at some point in time) – Gigala Jul 8 '16 at 6:54

    @Gigala maybe sometime if they commit the crime of adding pokemon other than gen 1 – Theyna Jul 11 '16 at 23:26

    The mathematical expectation of Eevees needed to get all 3 eeveelutions is 36 (a bit lower if you hatch an Eevee because this will give you a bunch of candy) – kcborys Jul 12 '16 at 19:38

    @Theyna They already confirmed at E3 that they'll be adding the full roster of pokemon at some point – Pyritie Jul 14 '16 at 10:48
  • I heard some(?) of Gen II is here, any Espeon or Umbreon info? – NoOneIsHere Dec 16 '16 at 7:15

According to this post on the /r/pokemongo subreddit, you can force your Eevee to evolve a certain way by changing its nickname before evolving it to:

  • Pyro to evolve into Flareon.
  • Sparky to evolve into Jolteon.
  • Rainer to evolve into Vaporeon.

(These are the names of Eevee Brothers from the TV series/Manga)

You can also, as of the Generation II update, use nicknames to evolve into a certain Eeveelution, but like before, this works only once.

  • Tamao to evolve into Umbreon.
  • Sakura to evolve into Espeon.

This now works with the Generation IV evolutions Leafeon and Glaceon. When renaming Eevee the first time, the evolve button with display the evolution it will evolve into rather than a question mark.

  • Linnea to evolve into Leafeon
  • Rea to evolve into Glaceon

This technique will only work once per evolution. For example, if you have already evolved an Eevee named Rainer into a Vaporeon, evolving another Eevee named Rainer will result in a random evolution.

Evolving without the naming tricks will give you Flareon, Jolteon or Vaporeon by random chance.

Also, according to another reddit thread, by walking 10km with Eevee as a buddy you will get Espeon when evolving during the day and Umbreon when evolving during the night.


Normally, evolving an Eevee will randomly result in either a Vaporeon, Jolteon, or Flareon with a 1/3 chance of either of them.

If you keep Eevee as your buddy for 10km, earn at least 2 candy with it whilst it's your buddy, and then evolve it whilst it's your buddy, it will evolve into either:

  • Espeon if evolved during the day.
  • Umbreon if evolved during the night.

It is day if the game screen in overworld and when catching Pokemon is bright, and night if this screen is dark. The times when the game screen changes varies depending on your GPS and time location.

If you purchase a Moss Rock from the Pokemon shop (for 200 coins), place it on a Pokestop, spin the Pokestop, and then evolve Eevee whilst in the radius of the Rock, it will evolve into Leafeon. The same applies for Glaceon with an Icy Rock. The silhouette of Leafeon/Glacoen will appear if these requirements are met prior to evolution - if it doesn't, the requirements are not met and it would evolve into Vaporeon/Jolteon/Flareon.

You can also choose a nickname to force a specific evolution as per this answer - it only works once per nickname/evolution.


According to this site, stones are available after the gen 2 update. Other than the naming tricks, there are other ways to control some evolution forms:

Walk with the Eevee for 10 kilometers and stay it as your buddy, then evolve it during: day – Espeon; night: Umbreon.

There may be other better ways to control evolutions, but haven't been found out by all trainers.


In addition to the first three evolutions mentioned by @Brant, with the addition of the second generation there are two more Eevee names that will trigger a guaranteed evolution once:

  • Tamao for an Umbreon.
  • Sakura for an Espeon.
  • 2
    I've edited it into @Brant's original answer. This is a useless answer now. – haykam Feb 17 '17 at 3:31
  • This should also be added to answers of this question. – Jouramie Feb 17 '17 at 3:37

    @Jouramie that is not necessary. That was marked a dupe of this question so users will be redirected here anyways. – Vemonus Feb 17 '17 at 3:53

It depends on what move your Eevee knows when you capture it. Here is the move to evolution chart :

  • Swift - Vaporeon
  • Dig - Jolteon
  • Body Slam - Flareon

    Do you have any source? – Jouramie Jul 9 '16 at 22:28
  • This was a theory of mine that I will have to test. Would love it if this was the case. Still need more candy though :( – user66184 Jul 9 '16 at 22:36

    I'm seeing people test this on reddit right now, and if you look at the people posting results, you'll see that there are people whose "Dig" Eevees evolved into Vaporeons and Jolteons. – pushasha Jul 10 '16 at 3:30

    I tried this last night. Myth busted. Could post video proof in the evening if really necessary – kcborys Jul 12 '16 at 19:19

Well I've evolved two Eevees so far and I've had my friend evolve one and this is the conclusion I came to:

It depends on your team. I am Team Mystic (blue) and both times i got Vaporeon, my friend is team Valor and he got Flareon.

Is there anyone who disagrees? ^_^

    That is a possibility, but it's hard to believe without sources as it would mean that at all you can't capture every Pokémon. – Jouramie Jul 10 '16 at 0:05

    I'm on Team Blue and got Jolteon, so I don't think this is correct. – pushasha Jul 10 '16 at 3:23
  • 5
    Team Yellow and I got Vaporeon. – AlannaRose Jul 11 '16 at 6:38
  • Furthermore, when they add Gen2 Pokemon (what I think will eventually be done) this theory breaks, too. Or they would add Team Black and Grey. – h0ch5tr4355 Jul 11 '16 at 8:42
  • Mystic, and I got Jolteon. – NoOneIsHere Dec 16 '16 at 16:20
