The Google Maps app turned into an old-school video game with the addition of a "Play Snake" feature. Tap on the snake icon, hit play and choose from a selection of destinations, including San Francisco, Tokyo and Cairo. It puts you in control of a red double-decker bus, street car or other city-appropriate mode of transportation. You then have to snake around and pick up passengers. It's a fun bit of retro entertainment.

Google says the interactive joke will stay live for about a week, though you can head over to a special Google Maps Snake website to play after the app prank is over.
