Gym Mission
The sixth Pokemon Gym in Pokemon Sword is found in Circhester, and its a Rock Type Gym. The Mission for this Pokemon Gym sees players having to navigate through tile puzzles full of trainers where various tiles will collapse when walked upon, sending you directly back to the start of the last platform you were on. When entering the Pokemon Gym, you will be given sensors that will help you get through the puzzles, vibrating as you get near a tile piece that will collapse. The further you make it, the longer the puzzles become. The final puzzle will even include a sandstorm that makes it difficult to see.
