The game uses a top-down perspective and turn-based battles. The player explores towns, routes, caves, and other areas, catches Pokémon, trains a party, collects items, and battles Gym Leaders, rival trainers, and other opponents.

Most Gym challenges can be attempted in different orders, with enemy levels adapting to the player's progress. The player can travel between Johto and Kanto, choose from multiple starting locations, and continue exploring after completing the main objectives. Battles use the traditional four-move system, type matchups, status effects, evolution, and party management.

Build a balanced party with different types and maintain several Pokémon near the expected level of the next major battle. Because progression is flexible, exploit type advantages rather than relying only on level increases.

Explore thoroughly for Hidden Items, useful TMs, and optional encounters. Keep healing items available, teach field moves carefully, and use the Pokédex and move descriptions to plan around Gym specialties.
