PokéStop Showcase

PokéStop Showcases are contests that are held at PokéStops in Pokémon GO during certain events. PokéStop Showcases allow Trainers to leave a Pokémon at a PokéStop to enter a timed contest for rewards. Each Showcase features a certain species and a requirement to be judged against.

Details
Each Showcase judges a specific Pokémon species under a specific criteria. The Pokémon is given a certain amount of points based on how well it meets the criteria. A leaderboard can be viewed to see how each participant's Pokémon placed.

PokéStops hosting PokéStop Showcases have an unique icon above them. Prior to entering a Pokémon, the Showcase icon above the PokéStop is green. After entering a Pokémon, the icon turns purple. Trainers must be in range of the PokéStop to enter the Showcase. Showcases take place at the same PokéStops throughout a Season.

Unlike leaving a Pokémon to defend a Gym, entering a Pokémon into the Showcase does not lock it at the PokéStop; it is still able to be traded, transferred, form changed, or evolved. The Pokémon at the Showcase can also be swapped out for another that meets the same criteria. Remote swap outs are possible after entering a Showcase.

Each PokéStop Showcase can support 150 entrants. An individual Pokémon can only be entered into one Showcase at a time. Each Trainer can only enter 3 Showcases at a time.

The Contest medal is unlocked and leveled up for trainers placing first-place in 1, 10, 50, and 100 contests.
