The basic premise of Collection Challenges in Pokémon GO isn’t much different from Timed Research tasks. To access a currently live Collection Challenge, go to the Today View where Timed Research is located. There, you will see the challenge, which challenges trainers to catch a specific collection of Pokémon. All of the species’ sprites are pictured there and, when one is caught, trainers are alerted that they’ve made progress the exact same was as with Research. Trainers must catch just one of each tasked species in order to complete the challenge.
