The whirlwind success of Pokémon Go has added US$7.5-billion to Nintendo’s market value over the course of a few days, but it’s also sparked a series of bizarre misadventures as scores of budding trainers try to “catch ‘em all!”

The free app-based game for Android and iOS uses your device’s GPS and clock to layer the game onto the real world, allowing wannabe Ash Ketchums to hunt and catch the prized pocket monsters with their camera and smartphone screen.

The Pokémon Go was installed on more than five per cent of Android devices in the U.S. just two days after its release, according SimilarWeb Ltd. The UK-based market research firm found the app was being used for an average of 43 minutes and 23 seconds a day. That’s higher than WhatsApp, Instagram, Snapchat, and Facebook Messenger.

While social media has been flooded with jokes about lazy gamers leaving their parents’ basements, feeling the sun on their skin, and getting some actual exercise; the reality of gaming in the real world has had some unforeseen consequences.
