They’re baaack! Pokémon—those cute but annoying Japanimated critters from the nineties—are all the rage once again thanks to Pokémon Go, a crazily popular smartphone game that challenges participants to “capture” virtual Pokémon by heading to specific real-world locations via GPS. To help you hone your gaming skills, the app will even point you to Pokémon Go “gyms” in your area—basically public places where you can meet other fans and even a “trainer.”
