Explore the Kanto region from a top-down view, talk to characters, collect items, solve simple environmental obstacles, and travel between towns and routes. Wild Pokémon appear in designated areas, while some battles against Trainers are mandatory.

Capture Pokémon with Poké Balls, form a party of up to six, and use turn-based moves in battle. Pokémon gain experience, level up, learn moves, evolve, and can be exchanged with other Game Boy Pokémon games. Progress is mainly measured by defeating eight Gym Leaders, obtaining their Badges, and overcoming the Elite Four and Champion.

Build a balanced party with different types and reliable status or support moves. Keep several Pokémon trained near the same level so important battles do not depend on one attacker.

Carry healing items, antidotes, and Poké Balls before entering caves or challenging a Gym. Pay attention to type matchups, but also account for move power, accuracy, and the opponent’s level. Save before major battles and before attempting difficult captures.
