Pokémon Trozei Series
The Pokémon Trozei games are a series of puzzle games, with 2 released games between 2005 and 2014. In these games, the goal is to clear the field of Pokémon by creating rows and columns of the same species of Pokémon before both screens fill up with Pokémon. Getting a row or column of Pokémon and clearing them - "Trozei-ing" them - will additionally add that Pokémon's species to the game's Pokédex equivalent.
The following games are part of the series:
- Pokémon Trozei (Pokémon Link in Europe): Released for the DS in 2005 (Japan), 2006 (all other regions except South Korea), and 2007 (South Korea). All of the first 386 Pokémon can be obtained, although Legendary Pokémon cannot be obtained without using the DS' local connection to play with other players who own Trozei.
- Pokémon Battle Trozei (Pokémon Link: Battle! in Europe and Australia): Released for the 3DS in 2014. All of the first 718 Pokémon can be obtained.
