Gym (Pokémon GO)

A trainer can claim a Gym with other trainers.

If a trainer finds a Gym on the local map, which is colored silver, the trainer can take it. Once taken, the trainer, or someone from their team, can place a Pokémon to defend the Gym. The Gym can store additional Pokémon the more prestige it has. The Gym can also train Pokémon, but it does not increase the Pokémon's Battle Points. Inside the Gym, trainers can battle against each other.

To attack, the trainer has to tap the phone to let their Pokémon attack the opponent. The more Pokémon battles, the more energy it stores for a greater attack. Trainers can bring up to six Pokémon. After the battle, the trainer can have a rematch with the Gym at any time.

Prestige is valued by the battles the Gym has. The more victories the Gym receives, the prestige is increased; likewise, if the Gym loses a battle, its prestige is lowered down. Once the prestige is at 0, the trainer loses the control of the Gym, whose color turns to silver and can be taken by anyone.
