When you consult <LINK>our list of Pokémon that can evolve<LINK> with a Sinnoh Stone, you realize that there are many of them! Until now, the only way to obtain this precious object was as a reward for completing seven Field Research tasks.
Unfortunately, the Sinnoh Stone is no longer a guaranteed reward for completing the 7-day series, and has become a random reward.
Other means of obtaining Sinnoh Stones will be added as they become available!
