Just days after being made available in the U.S., the mobile game Pokemon Go has jumped to become the top-grossing app in the App Store.
LOS ANGELES AP — Beware: "Pokemon Go," a new smartphone game based on cute Nintendo characters like Squirtle and Pikachu, can be harmful to your health.
The "augmented reality" game, which layers gameplay onto the physical world, became the top grossing app in the iPhone app store just days after its Wednesday release in the U.S., Australia and New Zealand.
The game was created by Niantic Inc., a San Francisco spinoff of Google parent Alphabet Inc. that previously became known for a similar augmented-reality game called "Ingress."
To play, you fire up the game and then start trekking to prominent local landmarks — represented in the game as "Pokestops" — where you can gather supplies such as Pokeballs.
