Google, as a search engine, has changed the landscape of Internet search. So much so, that the word 'Google' has entered the mainstream as a verb. If you can't find it, you can google it to know more. The developers at Googleplex always strive to devise software that's more amazing and more user-friendly than the competition is offering. But Google also has a sense of humor and isn't just complex codes and algorithms. Like a teenager, it dabbles in playing pranks. On special occasions, it spreads hoaxes, all the while promoting itself. Since we are still laughing at the hilarious outcome, take a look at these hidden Easter eggs that will give you a chuckle or two, and might surprise even the most frequent web surfer. If you ever happen to feel nostalgic while surfing the web, bring back fond memories by searching Google in 1998. It provides you a retro version of your searched web page before the turn of the millennium―it only gives you this feel on the first page, and not for the rest. Good thing the world didn't end in Y2K, as it was supposed to, and gave Google a chance to better itself. If your company forbids you from accessing websites to channel or release your stress, try typing Atari Breakout in Google Images. It gives you a pinball style game that lets you relive the arcade games of the '80s. You can use it to take a break from work and break some tiles to beat other high scores. You can return to searching for images by clicking the 'Return to image search' button on the top. Typing Do a barrel roll in Google makes the whole page flip 180 degrees once. A very funny trick to show others or those still in awe of Google. You can also type 'Z or R twice' to see the same result. Typing tilt or askew in Google tilts the search page to one side. Type Google Underwater in the Google search bar and click on the first result. It features an underwater scene with sharks and other fish roaming their territory. Searching anything in it will try to sink the Google bar even further into the sea. Type and search to see how many search queries it takes to sink it to the bottom. Earlier, clicking on this particular button on the Google page led you to the first relevant result. Since then, Google has upgraded it to feature a variety of options. From I'm Feeling Trendy, which keeps you updated with the current events around the world to I'm Feeling Doodley, which lets you enjoy the number of doodles Google has created over the years commemorating some special occasions. Other than the two mentioned, if you hover your cursor over the I'm Feeling Lucky button, the various options rotate like a slot machine until it rests on a certain option. Each of the options directs you to a website characteristic of its name. It works on major browsers but only on the US-based Google website. Typing zerg rush in the Google search bar opens up an arcade game in Google, wherein the O's try to eat up the search results, and you have to shoot them down to stop that from happening. It's a tactic used by the Zergs in Starcraft to overwhelm enemies when they swoop down and attack in a group all at once. Try beating the highest score. Typing Google Gravity, increases the gravity within the page and the whole page falls down. You can even play with the different buttons and fling them across the page. After a while, the whole page is sucked in and vanishes...and is restored after you revert to the main website. Type Google Sphere in Google for an even better effect. All the buttons in the Google homepage revolve around its axis. But don't let that stop you from searching. Type Google Space in the search bar and click on the first search result. Watch the Google page experience a feeling of weightlessness and float away slowly. Type Epic Google in the search bar and click on the first search result. This increases the size of the Google home page till it becomes too big to handle. Similarly, typing Weenie Google shrinks the page till it's too small to search in. Type 'elgoog' in the search bar and click on the first search result. This gives a mirror image of the Google homepage. Searching in it will reverse the words as well as the results.
