Not only is it is exciting to see many fan favourites - such as Togetic and Magmar - be granted new forms, but it makes many of the game's best Pokemon even more powerful - including Rhydon.
There are many other special evolution items too - such as the Metal Coat for Steelix and Scizor, the Dragon Scale for Kingdra, the King's Rock for Slowking and Politoed, and the Up-Grade for Porygon2.
Update (February 1st): Six new Gen 4 evolutions using a Sinnoh Stone have been added! They are listed in our table, with the latest additions first.
How to get the Sinnoh Stone in Pokémon Go
Regardless of which creature you use the Sinnoh Stone on - the full list is mentioned later in the article - the methods in how to get the Sinnoh Stone remains the same:
- The Sinnoh Stone has a chance of dropping when collecting your seventh day Field Research reward
- A chance of dropping from completing PvP Trainer Battles
Great news, Trainers! All day during your region's #PokemonGOCommunityDay, you can earn five— Pokémon GO (@PokemonGoApp) February 11, 2019

This is different to other special evolution items so far - which require either the seventh day of your PokéStop Daily Bonus streak, or a rare drop from spinning standard Poké Stops and opening Gifts.
For now, it means it'll take some time for players to get every creature - right now, 11 weeks to be exact! (Unless, of course, you can trade some from others...)
Which Pokémon can use Sinnoh Stone in Pokémon Go?
There are a staggering 22 Gen 4 creatures that evolve from previous generations.
The ones that are currently available are as follows - their newest additions first - with their previous evolution listed, and the Gen 4 creature they become with the use of the Sinnoh Stone at that point.
Note you'll also need to use 100 Candy to evolve them, and with some creatures, a specific gender:
|Aipom||...evolves into Ambipom using a Sinnoh Stone and 100 Candy|
|Lickitung||...evolves into Lickilicky using a Sinnoh Stone and 100 Candy|
|Tangela||...evolves into Tangrowth using a Sinnoh Stone and 100 Candy|

The month of April offers Field Research, and new shinies. We've also recently seen the addition of Lucky Friends and Giratina counters. Meanwhile, take a look at the Pokémon Go Gen 4 Pokémon we're still waiting on, how to get a Smeargle photobomb as well as details of the next Community Day Pokémon Torchic.
Other Pokémon expected to use Sinnoh Stone in the near future
What about the remaining five, including Eevee evolutions Leafeon and Glaceon? It was previously assumed the Sinnoh Stone would also be used to evolve them, but that's not the case - at least right now.
Either developer Niantic is holding back these evolutions for another wave - the most likely cause - or there's an additional or even completely different mechanic in the wings to make them evolve.
What makes the list of Sinnoh Stone creatures different those that don't evolve yet are their methods from the main games - which require either having a set move or being in a set location before they can evolve.
Some already live require Stones in the main games - such as the Dusk Stone for Honchcrow and Mismagius, Shiny Stone for Togekiss, or holding a special item at night for Gliscor and Weavile - so the game isn't above making the process simple with a Sinnoh Stone.
Perhaps the rest will be the same too - it's just a case of waiting for them to be active.
Remaining Gen 4 evolutions we are waiting on are:
|No.||Pokémon||Type, Evolution and predicted catch method|
|462||Magnezone||Electric / Steel Type|
Evolves from Magneton (when leveled up using magnetic field in main games)
Evolves from Eevee (using a Moss Rock in main games)
Evolves from Eevee (using Ice Rock in main games)
|476||Probopass||Rock / Steel Type|
Evolves from Nosepass (when leveled up using a special magnetic field in main games)
