Did you know that Google run a daily puzzle challenge? The Google-a-Day sub-site is designed to improve your googling skills and of course help Google in their ever continuing thirst for knowledge.
Each morning at 00:01 EST (That’s 05:01 GMT), Google sets a new puzzle and also posts the answer to the previous day’s teaser. If you love cryptic crosswords you will love Google a day, and even if you don’t it is a great way to hone your search knowledge and skills.
Google have even made it easy for you to avoid finding other people’s posted answers by setting up a special search tool that hides all such comments, while still letting you use all your favourite google search skills.
Certainly worth checking out, but be warned it can be addictive.
