The Sootopolis City Gym has an ice floor puzzle. The gym floor is made of ice, and you need to step on every tile once to break it and reveal the path to the next floor. If you step on a tile twice, you'll fall through and have to restart the floor. There are several trainers (Swimmers and Beauty) scattered throughout, using Water-type Pokémon like Luvdisc and Sealeo. The puzzle requires careful planning and observation. Take your time and map out your steps. Battling the trainers is a good way to gain experience and prepare for the Gym Leader. Remember to heal at the Pokémon Center in Sootopolis City before facing the Gym Leader.
