The Hearthome Gym is a giant, five-story building constructed of gray stone blocks, and is illuminated by eerie gray-blue torches. On every floor, there is a simple mathematical puzzle and three doors corresponding with the answers. Picking the correct door leads to the next elevator up, while picking the wrong door leads to a dead end and a Trainer to fight.

In the Pokémon Adventures manga
The Hearthome Gym debuted in Drifting Drifblim, where entered the Gym with  and  in order to challenge Fantina. After clearing the math puzzles, she made it to the Gym Leader's room, where the Gym battle begun. Using Diamond's borrowed and her own, Platinum was able to defeat Fantina's  and  without too much trouble. Fantina then sent out, whose hallucination powers immediately took effect. Having studied the three Pokédex holders, Fantina knew exactly what kind of illusions would be most effective against their Pokémon.

Thanks to the illusions, Mismagius was easily able to defeat Platinum's Empoleon and, leaving her with just Lax. Against the gluttonous Pokémon, Fantina had Mismagius create an illusion of masses of food to distract it while the Magical Pokémon kept attacking it. Platinum was too confused by the illusions to fight back, making her chances of winning look slim. However, Pearl then noticed that Diamond, being a glutton like Lax, had no trouble with the food illusion, causing him to realize that Mismagius's illusions affect each people and Pokémon differently. Due to Pearl and Platinum's strong sense of reality, the illusions were causing them to have a headache, while Diamond and Lax had no trouble accepting the illusion and enjoying it. Upon realizing this, Pearl conveyed his findings to Platinum, who started playing along with Lax, much to Fantina's irritation. Just as Fantina was about to have Mismagius finish Lax off, the Big Eater Pokémon the Iron Ball it had been holding at Mismagius, defeating it and winning the battle for Platinum.

After the battle, Platinum revealed that she had chosen to use Lax in this battle due to Fling being a move, and thus super effective against Ghost-types. Adding to the move's power was also the fact that Iron Ball (which the group had discovered earlier in Celestic Town) was the most powerful item to use Fling with. Also, thanks to the drop provided by the item, Platinum had been able to turn Mismagius's  (which it had been using to create its illusions) to her advantage, allowing Lax to attack first. As a sign of her victory, Platinum was then awarded with the.

Trivia

 * The mathematics questions in this Gym are mostly basic addition and subtraction questions, which becomes somewhat of a running joke among the Trainers faced, some of which mention that the questions should have been impossible to get wrong with use of the Pokétch's Calculator App, and speculate that the Trainer must have chosen the wrong doors on purpose just to battle some Trainers.
 * Although the Hearthome Gym is the third in Platinum, it still shows up as the fifth Badge on the and Fantina's face is on the fifth slot.
 * The Gym in Platinum bears a striking resemblance to the Battle Pyramid, as the lighting there is also limited and a blue tile must be found to continue.
 * The inner part of the area where the Gym Leader stands usually is a color that corresponds with the Pokémon type that the Gym's theme is, but in Platinum, Fantina is standing on an orange inner ring rather than the Ghost type's signature purple like she was in Diamond and Pearl. This may have something to do with the fact that in Platinum, the Hearthome Gym is the third Gym faced by the player rather than fifth like in Diamond and Pearl. The orange that Fantina is standing on is similar to the signature orange of the Fighting type, the type of the third Gym in Diamond and Pearl.
