I run a weekly quiz (or at least I used to) and the best way is to avoid direct questions like what is the capital of X and have things like ditloids (18 H on a GC), or which actor links three films or which is the odd one out (give four things). I did a round recently which was titled "BJ or DT" and they were five quotations, you had to say which were by Boris Johnson and which by Donald Trump
I'm happy to email you my last 10 quizzes if you want to harvest some questions, send me a PM with your email address.
