Google's known for its weird and wonderful April Fools' jokes, but this year's edition might be the best we've seen. Because it's already April 1st in Australia and Japan, Google has introduced its "latest" build of Google Maps, laying down a "Pokémon Challenge" that requires you, a budding Pokémon Master, to discover and capture all of manner of creatures to fill up your Pokédex, simply by navigating to different places on Google Maps. To start playing, make sure you have the latest version of Google Maps for iPhone or Android, hit the search bar and select "Press start." You'll have to be quick though, you've got until 2am PT on April 2nd to catch 'em all.
