Welcome to Stadium Mode. Here you will battle using one of four different cup rules: Pika Cup, Petit Cup, Poké Cup, and Prime Cup. This section covers the Pika Cup and the Prime Cup, and the next section covers the Petit Cup and the Poké Cup.
There are four levels of difficulty: Poké Ball, Great Ball, Ultra Ball, and Master Ball. Defeating the eight trainers on one level will unlock the next.
