The newest (and possibly cutest) Pokémon game, Pokémon Café Mix, has been downloaded 5 million times on mobile devices and Nintendo Switch.
To celebrate this monumental achievement, Pokémon Café Mix players will receive bonus items by logging into the game between 11:00 PM PST on August 16 and 10:59 PM PST on August 29, 2020. Players will automatically get 5,000 golden acorns and three each of the Whistle ↔ and Whistle ↕ puzzle powers.

Additionally, Grookey, the chimp Pokémon, will appear for a limited time as a special customer from August 11 to August 25, 2020 as well as other Pokémon “stopping by”.

Pokémon Café Mix is a free-to-play game available to download now for Nintendo Switch and from the App Store and Google Play.
My Opinion:
You can count me as one of the 5 million people who downloaded this wonderful game. I did gradually stop playing, but I may pop in to see the cute grassy Grookey and enjoy the free gifts!
