Party Challenges are tasks that players can complete together while playing in Party Play mode in Pokemon Go. Each challenge is predetermined with its own set of rewards, and the ones youll face are selected by the party host after everyone has joined Party Play. Once a Party Challenge has been completed, the host will be able to choose another one. Theres a range of different Party Challenges youll be faced with, including spinning PokeStops or Gyms, catching Pokemon, catching a specific type of Pokemon, and battling in raids. Some of the rewards you can earn include Stardust, Great Balls, Ultra Balls, and Razz Berries. You can check your progress with the Party Challenges by either opening the Party tab from your Trainer Profile or selecting the Party Play button on the Map screen. If you leave Party Play early, then you wont receive the rewards earned from completing Party Challenges. However, players are limited to one hour of Party Play, and after that time runs out, the group will lose all progress on unfinished challenges and have to re-create the group to receive new ones.
