There are a host of useful quiz sources on the Internet. Here are a few of the ones I’ve found most useful down the years.
This cavernous website has a huge number of different rounds. It is particularly good for pictures, including dingbats and other puzzle rounds.
Quiz Zone https://www.quiz-zone.co.uk/
While not the easiest to navigate, a bit of persistence will get you to plenty of great rounds and ideas for your quizzes.
Paul’s Quiz https://www.paulsquiz.com/
Although a premium version exists, I’ve found lots of inspiration and ready-made rounds from the free version. It’s got a very good menu system too, so it’s easy to find exactly the type of questions you’re looking for.
Ken’s Quiz https://www.kensquiz.co.uk
Another vast resource, which also has a novel quiz generator tool. Some useful advice on how to organise a quiz too.
Ready Made Pub Quiz https://readymadepubquiz.com
Again you’ll find a mixture of free and paid-for resources.
Ken’s Dingbats https://www.kensdingbats.co.uk
As the title suggests, this site focuses on dingbats and other word puzzles.
