Back in May 2017, The Pokemon Company announced a new mobile pokemon game titled Pokeland and launched a beta version of the game for Pokemon fans to try. After two years, The Pokemon Company renamed the game to Pokemon Rumble Rush and officially released the game.
Pokemon Rumble Rush is a mobile exploration game where players can collect different pokemon by exploring different areas. The pokemon they catch will be able to help them clear harder difficulties, raising the max CP of the pokemon they catch and unlocking more regions to explore.
