 Developed and managed by DeNA, "Pokémon Masters" allows players to collect teams of Pokémon trainers and masters, along with their favored Pokémon, and create teams of three that can be used in battles with computer or human opponents.The game tracks the amount of time a user sleeps, using the accelerometer of the external Pokémon Go Plus + accessory, and communicates the data to the user's mobile device via Bluetooth for sleep-related game play.Though not much is known about the exact game play yet, The Pokémon Company has promised it will turn "sleeping into entertainment" in a similar way to how the Pokémon franchise's other mobile game, "Pokémon Go", turned the act of walking into entertainment.
