Before the game
Keep it short
A game that goes on forever gets boring, especially in a big group.
Make it easy
Jeopardy isn't only about knowing the answer, but also about buzzing in first. Pick questions most people know, and they'll want to buzz.
Write it together
Quizzes are often better when more people make them. Invite friends into the creator and build on each other's ideas.
Use images, music and videos!
How about a “finish the lyrics” where you play part of a song? Or show a landmark and ask which city it's in.
Mix in multiple choice
Fun when you're many. More people get to play, instead of the same team buzzing in every time.
Host from your phone
Show the board from your laptop and control the game from your phone. No walking back to pick each question, no answers on a separate sheet.
How many are you?
2–4
The regular size for Jeopardy. Everyone plays for themselves.
5–10
Mix in some multiple choice, so more people get to answer.
10+
