In Rumble U, the player controls Pokémon and battles alongside them against other Pokémon in battle arenas. A boss Pokémon must be fought at the end of every battle arena. As the player advances, new battle arenas are unlocked. Further battle arenas can be selected from a menu. Progressively, battle arena difficulties continue to rise. Once a battle arena is completed, the player is rewarded with coins and new Pokémon. The game also uses figurines to add content to the game. (wikipedia.org)
