Pokémon Battle Trozei is the sequel to Pokémon Trozei! In this puzzle game, players battle wild Pokémon and attempt to catch them. The game is played by lining up three or more Pokémon in a row to create a Trozei. Making two or more Trozeis in a row will add combos. If the player lines up four Pokémon and then three Pokémon in the same combo, they get a Trozei Chance, meaning only two Pokémon are needed to make a Trozei. Upon reaching a Trozei, the Pokémon in the Trozei goes to the top screen. After a combo ends, the Trozeied Pokémon attacks the wild Pokémon. This will whittle down it HP. Trozeiing five or more Pokémon in a straight line initiates a Scatter Attack, which attacks multiple wild Pokémon. Six or more initiates the stronger Double Scatter Attack. Like the first game, Ditto can be used as a "free space" that can be lined up with any Pokémon. Also, Trozeiing Chansey will restore HP to the Trozei Box. The wild Pokémon will occasionally attack the Trozei Box. When its HP is gone, the game is over. However, when a wild Pokémon loses all its HP, it can be caught and it will be added to the list of Pokémon who may appear in the Trozei Box.
