How to get sinnoh stone pokemon go - Pokémon Aller's celebrates unique evolutions through an Evolution event, highlighting the creative way Pokémon evolves throughout the series. Several of these evolutions sometimes require the trainer to increase a Pokémon's happiness, while others require a particular stone.
In this case, you have the option of acquiring two special stones, the Unova stone and the Sinnoh stone. Trainers will need it to evolve, in their party, specific Pokémon for transformations specific to the Sinnoh and Unova region.
Fortunately, trainers shouldn't have too much trouble acquiring these useful stones and using them on their favorite Pokémon. You receive them by completing the research tasks for the Evolution event.
You receive a Sinnoh Stone for completing the research task of hatching seven Pokémon Eggs, and you receive the Unova Stone for winning three battles against The Rocket Leaders Team GO.
You can probably do these tasks at once, as it takes a bit of work to locate a Rock GO team leader, so make sure you have multiple incubators and can throw a few Pokémon eggs in them from close range.
