It's Friday, so why not waste a few minutes this morning with Google's latest playable Easter Egg?
Typing "zerg rush" in Google.com seemingly returns the regular Google search results for this unusual term, but soon, little O's (from the Google logo) start dropping from the top of the page.
Use your mouse to click and destroy the O's - or zerglings - before they eat your search results and gather into two, large G's on the page. At the end of the game, you can share your scores via Google+, telling followers how many zerglings you took down.
As described by knowyourmeme.com, the term Zerg Rush originates from the real-time strategy (RTS) game Starcraft. "The 'Zerg' race is notoriously known for its ability to mass-produce offensive units within a short time frame, thus allowing the player to overpower the opponent by sheer number," the website said.
News of the game quickly made the rounds this morning, with "Zerg Rush" topping the trending topics on Google+ and Twitter as users urged friends to try it out.
"Just Googled 'Zerg Rush' and spent the next 40 minutes clicking on O's...I think I need to get a life...still; it was good fun!" one user tweeted this morning.
"Type "Zerg Rush" into Google. If you've ever spent any time with an #RTS, you'll enjoy the results. #GG," another person wrote.
Google has offered up a number of Easter Eggs over the years. On Valentine's Day this year, typing in a specific equation resulted in a blue heart on a graph.
Over the holidays, meanwhile, Google released the "Let It Snow" and added lights to its results pages for "Christmas" and "Hanukkah" searches. There's also the "do a barrel roll" meme, as well as "Tilt." A 2010 playable Pac-Man homepage doodle, meanwhile, was so popular that it resulted in a standalone page and zapped about 4.8 million hours of productivity.
As PCMag reported in 2010, there's a hidden world of harmless pranks coded just beneath the surface of many popular websites like YouTube, Facebook, and Google; undocumented tricks to entertain and amuse. Click on the slideshow below for eleven Easter Eggs and share more in the comments below.
