Google has hidden a selection of jokes, games and fun features that can help waste away a few fruitless hours ahead of the weekend. Here are the best ones:
1. Google time travel
To celebrate Google's 15th birthday in September it released an Easter-Egg to let you see what Google used to look like when it was first created.
If you google 'Google in 1998' the search engine travels back in time to give you a glimpse of its pre-millennium look.
2. Barrel Roll
The Barrel roll easter egg was introduced nearly two years ago but is still entertaining to those who haven't seen it before.
By typing the phrase 'do a barrel roll' into Google search, the browser does a 360-degree turn.
It was initially created by Google's software engineers to showcase the power of CSS3 - the language used to control the layout of web pages.
But beware, there is a strong chance of motion sickness with this one.
3. The answer to everything
Google has developed an Easter Egg in tribute to Douglas Adams's The Hitchhiker's Guide to the Galaxy.
It uses the answer to the ultimate question provided in the novels.
Ask Google 'the answer to life, the universe, and everything' it gives you the answer; 42. It is just the question that we do not understand.
4. Off kilter
If you try typing 'tilt' or 'askew' into Google, the search engine obliges by displaying the responses at an angle.
Handy if you are reading on a wonky screen, but otherwise disconcerting.
5. Me hearties
As well as the standard languages, Google also has a Pirate interface and one for the Muppets' Swedish Chef.
Originally released back in 2008 to mark Talk Like a Pirate Day, this Easter Egg has stuck.
Get in touch with your inner Jack Sparrow and give it a try.
6. Word play- Google style
Recursion is the process of repeating items in a self-similar way. Google have created an especially nerdy Easter Egg using this.
By typing "recursion" into the search box it suggests "recursion" as an alternative, sending you on a loop of clicks that all generate identical results.
7. In joke
If you search for anagram on Google, the top result is, in fact, an anagram.
8. Hobbit house
Typing in the Shire and Morder into the directions box provides handy walking directions for anyone intending to venture on a quest to save Middle Earth.
However, the directions come with a warning: "Use caution - One does not simply walk into Mordor."
The line itself is spoken by Boromir in The Lord of the Rings. Both the Shire and Mordor are provided as real places on a map, with several options around the world.
Simply find the closest to you and set off on your very own quest.
Google Maps features a TARDIS which users can enter outside Earl's Court underground station.
Doctor Who fans can move around the console room of the most up-to-date version of the space and time machine.
By searching for 'police Telephone Box' in Google Maps the search immediately takes you to the location in South west London.
Using Street View you can enter the old fashioned police box positioned outside the station by clicking the double white arrows in front of the box.
10. Come fly with me
Google Earth has a flight simulator feature which allows you to operate a simulated aircraft using either your mouse or another controller.
It lets you fly around the world in a choice of different planes. To enter the flight simulator simply press Ctrl-Alt A.
The simulator offers you two different aircraft and a range of controls to explore the world from above. Very addictive.
