Players will return to the Johto region for more exploring and turn-based combat with Pokémon creatures, albeit with improved visuals and added touch-screen support. Gameplay in HeartGold and SoulSilver is mirrored after Pokémon: Gold Version and Pokémon: Silver Version on Game Boy Color. Two Pokéwalkers can also wirelessly communicate with one another for trading purposes. As an added bonus, Pokémon that have been downloaded to the Pokéwalker will earn experience points while you walk, allowing the creatures to gain one level after being transferred into the main game. Any captured creatures or acquired items can then be transferred to the main HeartGold or SoulSilver cartridge for use in the game.

Every step you take earns you 'Watts,' a type of energy used to capture wild Pokémon or to locate hidden items from within the Pokéwalker. Each version is bundled with a 'Pokéwalker' accessory, which tracks your steps on an LCD display. Pokéholics are encouraged to take their adventurous spirit away from the DS and into the great outdoors with the release of HeartGold and SoulSilver.
