Pokémon Shuffle
Gameplay. "Pokémon Shuffle", similar to "Pokémon Battle Trozei", is a puzzle game in which players fight against various Pokémon by matching three or more of the same Pokémon from the Kanto, Johto, Hoenn, Sinnoh, Unova, Kalos and Alola regions on their bottom of their screen. Players accomplish this by swapping around Pokémon on the bottom of their screen. Players can take up to four support Pokémon with them, some of which can deal additional damage depending on their type (e.g. matching water-type Pokémon causes extra damage to fire-based opponents). Players progress through each stage by defeating  the opposing Pokémon within a set number of moves, after which the player receives in-game coins and their Pokémon gain experience. Upon clearing a stage, players will have a chance to catch the Pokémon; the quicker the player defeats a Pokémon, the higher probability they have of catching it. If the player fails to catch it with their first Pokéball, they can spend coins to use Great Balls with a doubled chance of success, or retry the stage at a later date. Defeating Pokémon trainers earns Mega Stones, which allow certain Pokémon (if they have been successfully caught) to  undergo Mega Evolution once a player has matched enough of them during a stage, granting bonus effects when matched. Players can also unlock Expert levels, which require the player to defeat a Pokémon within a time limit using unlimited moves. The game follows a freemium format in which the player requires hearts to attempt each stage, with the player able to recover up to five hearts by waiting a certain amount of time. Players can also use coins to purchase power-ups, such as extra moves, prior to entering a stage. Extra hearts and coins can be purchased with jewels , which are either earned by defeating trainers or purchased using Nintendo eShop funds. The game supports internet connectivity which offers bonus items and special limited-time stages to those who check in, as well as StreetPass functionality. Release.
