, released as Pokémon Link: Battle! in Europe and Australia, is a Pokémon-themed puzzle video game for the Nintendo 3DS and is the sequel to the 2005 Nintendo DS title Pokémon Trozei!. It was released in the Nintendo eShop in Japan on 12 March 2014, in Europe on 13 March 2014, in Australia on 14 March 2014, and in North America on 20 March 2014. The game includes all 718 Pokémon that were known at the time. Gameplay The gameplay of Pokémon Battle Trozei is similar to the Japanese mobile game Puzzle & Dragons. In the game, players engage in a Pokémon battle depicted on the top screen of the handheld device. To battle the enemy Pokémon, players create groups of three or more identical Pokémon icons on the grid in the bottom screen. The battles are fought using a rock-paper-scissors style system where each Pokémon has different elemental types assigned to it, and the outcome is based on the strengths and weaknesses that these types have on each other. This mechanic of elemental strengths and weaknesses borrows from the main Pokémon role-playing games. This is the first Pokémon puzzle game to borrow rules from the main series. In addition to the matching mechanic, the game requires strategy when considering which Pokémon types to use in battle. This strategy element puts players that are unfamiliar with the Pokémon series at a disadvantage because they may not know the element types of each of the game's 718 Pokémon. The game supports cooperative multiplayer for up to four players. The game features the same Pokémon from Pokémon Trozei! but also features Pokémon from Sinnoh, Unova and Kalos, except Diancie, Hoopa and Volcanion. Development The game was revealed on 13 February 2014 in a Nintendo Direct, and was released in the Nintendo eShop in Japan on 12 March 2014, in Europe on 13 March 2014, in Australia on 14 March 2014, and in North America on 20 March 2014.
