The four Pokémon Stadium tournaments contain 80 total battles.
Pokémon Stadium is a Nintendo 64 battle game that focuses on competitive Pokémon matches rather than a conventional role-playing adventure. Its Stadium mode is divided into four in-game tournaments, each with its own rules and restrictions, and together they require 80 battles.
The game also includes Gym Leader Castle, where players battle the eight Kanto Gym Leaders, the Elite Four, and the Champion. Pokémon can be transferred from Pokémon Red, Blue, and Yellow through the Nintendo 64 Transfer Pak, while the game also supplies teams with predetermined movesets.
The number 80 applies to the four Stadium tournaments collectively, not to every battle available in the entire game. Players may also take part in other modes, including free battles and the Gym Leader Castle, so the game’s total playable battles are broader than the tournament count.
