Split into 14 different categories (ranging from Entertainment and Gaming to Geography and Religion) Sporcle has hundreds of games (quizzes) to keep anyone occupied for hours. Just be warned - it's more addictive than Double-Entry Accounting.

Jeremy the Trainee takes Sporcle a little too seriously. That said, he can now name every 80's sitcom

It could not be simpler - pick a category and a quiz, hit start and type your answers in the box provided. If you're right the answers appear in the right slots. How can something so simple be so addictive?

For us the Sports and Geography quizzes are an absolute must. We're pleased to say we can now name 183 countries in the world (out of 195) and have learnt interesting facts such as the smallest countries being (in no particular order) Vatican City, Palau, Tuvalu and Nauru. Smug? Yes we are. Knowledge is power and right now we're the global equivalent of... oh let's say... Sao Tome and Principe. A little way to go then...

With new and varying quizzes each day on such interesting topics as "Countries of Asia", "Cartoon Couples" and "Movie Posters" you are surely to find something that interests you. Unless you dislike knowledge... But why would you do that?

Sporcle divides its games by most popular over that day and the last 7 days, 30 days and all time as well as listing the new games each day. It makes it that little bit easier to navigate. Definitely a great way to spend an hour. Or a day. Just don't forget to eat lunch.
