The player searches the room using the 3DS' camera to destroy Dream Clouds and harvest Dream Orbs. There are two types of Dream Clouds; Pink and Stormy. Only in Stormy clouds are there Pokémon. After harvesting the Dream Clouds and leaving the Interdream Zone, only one Dream Cloud will be restored with the rest being restored at one per every 5 minutes. Players can pay 5 Play Coins up to 3 times a day to restore all the Dream Clouds. Initially, there are only Pink Dream Orbs but, after each genie is caught, an additional color is added. Depending on how often orbs of a certain color are collected, certain Pokémon may appear.
As the player progresses, they will unlock special extensions which will change what Pokémon appear. Some of these extensions require Dream Orbs to be paid while others use the Fourth Pokémon generation games with the game's cover Legendary Pokémon. Dream Orbs can also be spent on upgrading the equipment and acquire support items.
Connection with Pokémon Black and White 2
This game can connect to Pokémon Black and White 2 to deliver special Pokémon to the game. All the Pokémon had their hidden abilities (except for Rotom, which lacks a hidden ability) and this is one of the only ways to get the Therian Formes of Tornadus, Thundurus and Landorus. There are some difficult to find items to transfer as well like the Evolutionary Stones. Each Legendary Pokémon can be obtained once per save file and only be received per Black 2 or White 2 save file. They start at Level 5 if the game's save file is fresh without badges and go up to level 40 when the player has 7 or 8 badges.
The player helps Professor Burnet, who is studying the Interdream Zone.
