I’m going to be hosting a trivia event once a week for the month of January because traditionally that month is slow for the bar.
I need help with some good questions or subject. I was thinking of having five categories with each category having 6-8 questions.

Stay away from religion and politics
#1 history of Alaska
#2 history of bar snacks and food
#3 history of the founding of America
#4 history of Canada
#5 random facts
All can be easily looked up on the interwebs
As you can see, I like history

The Trivial Pursuit games have 6 catagories. Science and nature; entertainment; arts and lit; history; geography, sports and leisure so that could be one way one could divide things up.
The local contests I have participated in had 10 questions per catagory with 8-10 questions for each and there were 9-12 teams of 5-6 per team in those events. Many times the catagories were more local or state oriented so that is something to consider as well.
