Click on for 10 cool little-known fun features of Google.

Just punch 'Zerg Rush' in Google and you will find yourself defending your search results from an onslaught of zerglings that will try to eat them up. Want to save your precious search results from being obliterated? Just repeatedly click on these zerglings (which are basically red and yellow coloured Os) to eliminate them.

This is not all, Google is keeping score! A widget on the right side of the screen will show how many times you clicked to kill the enemy and the number you killed. If you are unsuccessful, the yellow and red coloured Os will wipe out all search results and assemble to form 'GG'. You can share the score with your circles on Google+ or clear the game and move on to search results.

Want to fly a fighter jet? Turn to Google. And, we don't mean for information, but to 'fly' a jet!

Google Earth allows users to fly a virtual jet right on their computer screens. To activate this feature, all you need is to simply go into Tools menu and select 'Enter Flight Simulator'.

On starting the simulator, you can choose the takeoff position and aircraft model. You can also enable joystick mode for the flight if your system supports the hardware.

Remember the arcade game Pac Man. The hugely successful game may appear outdated in the days of HD games. However, for many it still has its holds charm. So, if you are among those who would still love to play Pac Man, just hit Google. On the 30th anniversary of the game, the search giant made an interactive doodle that allowed users to play it using their keyboards.

Another cool Google trick that has been doing the rounds on the internet is the barrel roll. Just type Do a Barrel Roll' in your browser and you will see the whole page spin 360-degrees. Just refresh the page to repeat the effect.

Another cool interactive doodle was created on the 96th birthday of Les Paul, the inventor of solid-body electric guitar. Google's logo was redone to form a guitar that could be played using the cursor of the mouse or the keyboard. You can even record your tunes and Google will upload it on the web, so that you can listen to it again and save it as a media file on the computer.

During the London Olympics 2012, Google made a doodle for Hurdles, where a runner jumps over obstacles. This is an interactive doodle and allows you to race using the keyboard, with increasing level of difficulty. You can set your best score and even challenge your friends.

In 1960s and 70s, Moog Synthesiser was used by top musicians across the world to add depth to their music. Now you can do that too, as Google made an interactive Moog Synthesiser on its creator, Robert Moog's, 78th birthday.

The synthesiser can be controlled using the keyboard and mouse, and consists of features like mixer, oscillators, filters and envelope, which you can tinker with. You can record your own music and listen as well as share it on the web.

Tired of waiting for the YouTube video to buffer? You can play a round of 'Snake' in the meantime. The popular game of 1970s can be played by pausing an ongoing or buffering video by pressing either the left, right or down arrow key, immediately followed by the up arrow key. You can even play the game in full screen.

Another interactive Google offering is the Slalom Canoe doodle of London Olympics 2012. The game features a canoe, wherein a paddler is required to pass through the course in the shortest possible time.

You can control the canoe with your keyboard and need to avoid obstacles in the river while guiding the canoe through the check-points.
