The Simulation Challenge can be accessed in the Simulation Depot Beta. It is located in the Wireless Communication Depot in Fianga City, and is accessed by interacting with either of two characters stationed behind a counter on the second floor. Upon interaction with these characters, the player is able to select a trainer with whom they would like to battle whose ID number has been collected by the player. These IDs can be purchased from NPCs or sometimes are given to the player through NPC interactions. Each trainer in the Simulation Depot Beta can be battled as many times as the player likes, granting both money and experience to the trainer and their Pokémon. Many of the IDs that you will receive/purchase, are related to real-life people, such as the YOGSCAST.
