Please note that I am not looking to add new links.
- Jeopardy! Archive — Site that hosts most of the questions from the great American TV quiz show. Faithfully reproduced by the fans down to the last detail, it has 250,000+ clues (and counting)! It will take months to look at all the clues just once at this incredible site.
- JBoard — If you are a fan of Jeopardy!, you must visit this online board where the clues and the wagering strategies are dissected daily by a lively group of former, current, and future contestants, all of whom are devoted fans of the show.
- Quiz Bowl Archive — After I saw the Jeopardy! Archive website (the first link above), I thought it is unlikely that it would be surpassed as a quizzing resource. But check this out - the only flip side is that you have to download the documents. If you think you are a good quizzer, the collegiate packets will make you think again! The same site has tabs to the High School/ Middle School and Trash (Pop Culture) questions as well.
- Lizard Point — I cannot think of a better intro to geography than playing at this wonderful site.
- NAQT's Quick Reference — If you need to brush up on any quiz topic and don't have much time, these lists can be invaluable.
- Karnataka Quiz Association Quizzes — Am not very familiar with the Indian quizzing circuit but inadvertently came across this site. Not too many quizzes on this page but the paucity is compensated by the quality. Outstanding questions.
- Madrid Pub Quiz — This no frills site hosts more than 1000 questions, most of which are good.
