In Pokémon Battrio, the focus is on team-battling and has no Pokémon capturing in the game itself. Players have 'health bars', instead of the Pokémon. Pokémon must be bought through packs of randomly assorted pucks, which bear a resemblance to Pogs and have a picture of a Pokémon. To save a game, players buy a save machine for ¥600. The machine plugs into the arcade game, and allows players to make a character profile, save and use coins, and compete in the battle tower.
It is the first Pokémon title released for arcades.
