On October 2, 2015, Nintendo revealed that the title would receive a physical retail release in Japan the following month, with Nintendo of Europe later issuing a press release stating that an English retail version would also be arriving in Europe in January 2016. It was officially announced two weeks later by Nintendo on an Apedition of their Nintendo Direct broadcast, along with a worldwide release date set for the following week on the Nintendo eShop. The first mention of Pokémon Rumble World appeared in the game's entry on the Australian Classification Board content rating website in March 2015. Challenges, which are missions with a specific set of goals, may also grant Poké Diamonds, in addition to cosmetic items such as clothing.

Poké Diamonds can be used to unlock features such as increasing the chance to find certain Pokémon, in-game travel, continuing to play a stage after a Pokémon's health has run out, or additional Pokémon storage. After buying 3,000 of these, a mine will appear, granting 40 of them once per day. A limit on real-world currency use in-game does exist, however, and players are allowed to purchase a maximum of 3,000 Poké Diamonds through this method. The game uses a form of currency called Poké Diamonds, which can be obtained either through normal gameplay, purchased directly with real money through the Nintendo eShop, or exchanged through StreetPass. By taking direct control of their Pokémon, they can engage other creatures in real-time combat.

At the behest of the King, the player must travel to various lands battling and collecting new Pokémon to increase their Adventure Rank, granting them access to new items and areas. Pokémon Rumble World is an action game with a top-down perspective that has players assume the role of their Mii character in the Kingdom of Toys, a land populated by toy versions of 719 distinct Pokémon species.
