Plot
The story begins when the player has a strange dream. The player hears a Pokémon call for help, and sees a vision of Munna being chased by Hydreigon. The player then realizes that he has become a Pokémon, and is promptly transported to the Pokémon world. Upon arrival, the player quickly meets the partner Pokémon, and he asks where the player is from. When the player decides to tell the truth, the partner is at first surprised, but then accepts the player's story. The partner then asks the player to help him out with something.

The partner asks the player to help him get through the first dungeon, Ragged Mountain. The player then goes through the dungeon and out the other side. From there, the Pokémon come to a crossroad.

The Pokémon take the crossroad to a barren wasteland. There, Quagsire sells the land to the partner. The partner then begins celebrating his success, explaining to the player that his intentions were to build Paradise right where they were standing, and he asks the player to help. The player recalls the dream they had about Hydreigon chasing after a Munna, and realizing that he has no better place to be, he agrees.

The Pokémon then sleep through the night in front of a tree stump. The night is cold, and the partner suggests that they try to build a house the next day.

The next morning, Quagsire returns, and the partner tells him that they want to build a house. Quagsire says that he knows a good carpenter for them, and brings them through the crossroads to Post Town. They enter the inn, and Quagsire introduces them to Gurdurr. When the partner asks Gurdurr if he will help them build a house, he agrees, but only if they bring him five blue gems.

The player and the partner head to Stony Cave to find them. When the Pokémon reach the end of the dungeon, the blue gems are there. The partner takes five of them, and they promptly return to Post Town. On the way, a Scraggy bumps into them. Scraggy quickly apologizes and runs off, and the Pokémon return to the inn. However, when the partner tries to give Gurdurr the gems, he finds that they're gone! Gurdurr isn't upset, though; he simply tells them to go get more.

Exiting the inn, the player and partner are just about to head to Stony Cave again when the two Timburr confront them. They inform them that Scraggy had stolen their gems and to head to Hazy Pass to get them back. With that, the Pokémon head off to Hazy Pass. When reaching the sixth floor, they find Gurdurr and Scraggy conversing. Their conversation reveals that they were scamming the two. The Pokémon then confront Gurdurr and Scraggy and battle them. After defeating them, Scraggy runs away and the Timburr show up. The Timburr beg for Gurdurr to stop scamming others and to return to carpentry, but Gurdurr knocks both Timburr down, refuses, and walks away.

When the two Timburr get up, they explain everything to the player and partner. They tell them that Gurdurr used to be very fond of his craft, but one day Gurdurr got a serious back injury and was unable to build. They tell them that the last house Gurdurr ever built had his heart poured into it, but the client destroyed it after it was finished. After that, Gurdurr left carpentry and started doing bad things, like scamming. However, after being told this, the player and partner Pokémon continue to persist at Gurdurr building their house.

The Pokémon continue higher through Hazy Pass in pursuit of Gurdurr. When they find him at the top, Gurdurr attacks them. After being defeated, the partner explains that they want him to build their house. Gurdurr refuses, saying that he can't build anything worthwhile anymore. But your partner responds, saying he doesn't care as long as the house has Gurdurr's heart poured into it. Finally, Gurdurr agrees to put down scamming and return to carpentry, but not without sitting down and crying for a bit.

Several days later, Gurdurr and the Timburr finish the house, and the Pokémon sleep inside it that night. The next day, the Pokémon wake up and head outside, ready for another day.

He also explains that he had went to Stompstump Peak in search of crystals. The Pokémon, remembering the crystal they picked up, decide to give it to Dunsparce.

She explains that she was a lone adventurer, and that she had come to Post Town to see the Rainbows of Hope, four crossing rainbows that were said to inspire hope in the hearts of all who see them. Then, Dunsparce steps up and shows the crystal to Virizion, hoping to be friends. However, Virizion rejects him, saying that she doesn't believe in friends.

However, the Pawniard reveal four goonies to battle with them. But then, Virizion, the Timburr, and Gurdurr appear, ready to protect the others. The two sides battle, and after defeating the boss Pokémon, they all scram.

With everyone safe, Virizion tells Dunsparce to try not to trust others so easily. But the partner interjects, saying that trusting might not be so bad as Virizion says. He then asks for Dunsparce and Emolga to join them in their adventures, which they both agree to.

This is a new type of special attack accessed after the Team Badge is obtained. The player has to build this up in dungeons, using moves and defeating wild Pokémon. Once it's built up, the team attack logo will be displayed on the touch screen when L is pressed. It emits a green light and is significantly stronger than regular moves, attacking all enemies in the room and restoring HP, increasing accuracy, etc.

When there are no enemies in the room, the attack fails; however, the unused attack can still be performed while in the same dungeon at a later time.

Hubs and other out-of-dungeon locations
Some dungeons have floors where the player can roam around freely and has to complete various tasks in order to proceed. Items cannot be used outside of battle. They contain wild Pokémon, changing part of the floor to a regular grid-like dungeon floor during a battle. The player can escape from battle by stepping out of the grid.

The crossroads provides access to non-job request dungeons, Post Town and Pokémon Paradise.

Pokémon Paradise
Initially established by the partner Pokémon, this location progresses as the story does.

New mechanics

 * This game implements full 3D gameplay and depth perception via the 3DS's 3D capabilities. It also takes advantage of the 3DS's AR functions. By recognizing different round objects, it transforms them into a Magnagate, leaving an infinite labyrinth of dungeons to be explored.
 * Many Unova such as, , and  are included in the game, though some, such as  and , are oddly left out. Only a handful of Pokémon from previous generations appear in the game. A total of 144 Pokémon appear in the game. Despite this, a maximum of 288 Pokémon can be recruited.
 * Moves now have ranks. As a move is used, it gains progress towards the next rank. As a move ranks up, it grows in power, accuracy, and maximum PP. Status moves do not have ranks, and moves with set damage or moves that do damage based on factors such as the target's remaining HP (such as ) can rank up, but cannot increase in power. Move ranks are denoted by Roman Numerals, starting at I. As a move grows in rank, more uses are needed to raise it to the next rank. can also be built to train moves. Unlike using a move, Dojos add the same percentage of progress towards the next rank regardless of the move's current rank.
 * One of the other prominent features is mini-games, one of which is run by, allowing players to receive prizes based on how well they did on the game. This is a facility built in your paradise from Gurdurr.
 * Hunger is absent from a majority of the dungeons in the game, only appearing in the final three listed dungeons after clearing the story.
 * At the start of the game, the player starts off at level 7, but in all Pokémon Mystery Dungeon games prior to this, the player starts off at level 5.
 * There are obstacles such as a Poison Gas clouds, electricity, flames, vines, and bewitching mist that block the locked doors and certain pathways in dungeons. If a Pokémon of the type of obstacle is brought along with the player's Pokémon, the obstacle will disappear when the playable Pokémon touches it. Pokémon can eliminate the flames,  Pokémon can get rid of the electricity,  Pokémon can get rid of the vines,  and  Pokémon can get rid of the Poison Gas cloud,  and  Pokémon can get rid of the mist, and ice can be eliminated by  Pokémon.
 * When it rains, hails, sandstorms, or is sunny, the player may not heal their Pokémon's HP as they are walking. However, the player can still use items to heal.
 * Wonder Orbs may now be used during boss battles. There are no look-alike items in the game.
 * TMs may now be used an infinite number of times, just like in the core series.
 * Pokémon with more than one ability will only have one of them, like in the core series, as opposed to previous Mystery Dungeon games where both abilities were active.
 * After the main story-line, auras begin appearing in the dungeons, based on a "Mysteriosity" rating. In the main dungeon selection menu and on the Request Boards, there is a number next to a question mark from 1 to 5, which determines how likely it is for a "Mysteriosity aura" to appear on any given floor, with 5 being the most likely. This number is different every time the player enters the dungeon. This aura comes in a variety of colors and has a variety of different effects. Some of the effects include: Lowering or raising the enemies' speed, only a certain Pokémon appearing on the floor and being the only one encountered on that floor, not being able to recover HP, weather effects appearing, enemies put to sleep, Wonder Orbs not being usable, floors having no rooms and only corridors, and consumable items not being usable.
 * Mapless Streets, Uncharted Paths, and Gilded Halls are also new to the game. Mapless Streets are floors in a dungeon that do not have floor numbers. Once the player returns from the Mapless Street, the floor number they return to will be equivalent to how many floors they were gone for. Uncharted Paths and Gilded Halls contain a variety of different Pokémon and items in certain dungeons. If they occur in a mission, the player will be returned to the normal dungeon on the floor of the mission or earlier.
 * If the player fails to complete a dungeon, fewer items are lost and they keep their Poké.
 * There are certain designs and shapes on the ground that have different effects in dungeons. Yellow star-like shapes allow the Pokémon to attack twice automatically with the same attack when standing on the shape. Eraser-esque shapes on the ground make items that are thrown disappear when the Pokémon is standing on it. In Mt. Travail (DLC), there are tiles that will grant the effect of a Training Seed for the rest of the floor, etc. Mysteriosity aura floors may also have other special tiles.
 * Many main story-line dungeons can be entered through other dungeons. Dungeons that had no recruitment during the main story-line have recruitment after completing the main story-line.
 * Recruited and Partner Pokémon that are not brought into a dungeon still receive experience points when the player completes dungeons. Once the Pokémon are brought into another dungeon, the recruited Pokémon will level up from the experience it had gained without being absent from the group.
 * Damaging moves can now miss due to too high of defense or special defense and level, rather than just doing 1 HP of damage. It will say that the Pokémon "took no damage!".
 * Kecleon can no longer be recruited if defeated. There is no Kecleon Gift, and a Normal Gift and Premier Gift will fail if used on Kecleon.
 * Team Skills replace IQ skills that the older games had. Unlike IQ skills, Team Skills that are active affect all of the player's Pokémon. Treasure Boxes can contain new skills after being opened by Rampardos.
 * Traps can now occur at the entrances to rooms, unlike previous games where the first tile after a hallway was guaranteed to not hold traps.
 * Hostile Pokémon can now evolve if they're given a certain item instead of only by defeating player's Pokémon. This happens often in Magnagate dungeons.
 * If items are dropped in water, fire, or chasms, they are automatically placed on the nearest path, contrary to previous games where they were submerged or destroyed.
 * In previous Mystery Dungeon games, the job bulletin board will have two lists, but in this game there are five for both boards.
 * It is unnecessary to complete a dungeon in order to recruit new Pokémon, and they can also be sent back when the team is full.
 * Job requests can only be fulfilled one at a time, even if they are in the same dungeon.
 * Wonder Mail returns, but instead of being a long password that can unlock new dungeons and legendary Pokémon, it is an 8-character password and gives the player various items.

Dunsparce had gotten lost looking for a crystal to give to Virizion as a gift, because he wanted to be her friend. Virizion turns him down, saying she doesn't have friends. This hurts Dunsparce's feelings, causing him to run away. After rescuing Dunsparce again, she asks to join the team. The player's partner immediately accepts, much to Emolga's chagrin.
