You must navigate traps and defeat opposing Pokémon in turn-based battles. However, if your group fails in a dungeon, you lose all your items and your wealth.

You become one of 20 available Pokémon and set off on your journey. Along the way, you will encounter all known Pokémon, including legendary and mythical ones. With the help of your loyal Pokémon partner, you must investigate and combat the causes of troubling events, such as the petrification of Pokémon.

You choose two out of 20 available Pokémon: one that you will become and one as a partner. You explore a world where all known Pokémon can be found and dungeons change with each entry. Form friendships with Pokémon, apply turn-based strategies, and use combo attacks to conquer dungeons. Other players can assist you if your team fails.
