Pokémon Tretta is a spin-off arcade game developed by Marvelous AQL and Takara Tomy A.R.T.S., the latter being known for developing other Pokémon-related spin-off titles. The game uses a system called Tretta which are little tablets used by the player to use Pokémon in the game.
There are two main modes to Pokémon Tretta, them being Battle and Catch Mode and Quick Catch Mode. Battle and Catch Mode lets the players play the game normally, catching and battling Pokémon using the Tretta they have obtained. Quick Catch Mode allows for players to obtain Tretta if they do not have any, in which a sequence will play and a random Tretta will be dispensed from the arcade machine.
Tretta are small plastic tiles that are required to play Pokémon Tretta. A Tretta displays a Pokémon, its type, three possible moves it knows, and its stats (HP, Attack, Defense, and Speed). Tretta also come in different classes, with the lowest to highest classes being Normal, Super, Hyper, Master, Legend, and Ultimate. The first four classes are represented with stars ranging from one star on Normal to four stars on Master. However, Legend and Ultimate Tretta instead have an emblem stating their class. Higher ranking Tretta are also rarer and have stronger Pokémon.
- Pokémon Tretta is intended to be a predecessor to Pokémon Battrio, which follows similar mechanics and gameplay and was even released by the same company (Takara Tomy A.R.T.S.).
