TRIVIA & BINGO
You can do two different trivia topics with one each hour. People can come in as a team but creating teams of individuals to help them meet others is a great idea too. Creating teams of 6 to 8 people usually works well. Have 5 minute time to start where people are arriving and a 5 minute meet your team members to start the trivia session.
For one hour sessions we suggest 10 questions with 1 minute to ask the question and 3 minutes to answer it which is 40 minutes. Ten minutes to check the answers and award prizes for first, second and third place finishes up the hour. You might also get donations from local businesses for prizes.
Learning trivia is a possibility you might consider as one or two of the sessions along with popular trivia subjects. Learning trivia is where the person learns something in the 10 questions.
For Bingo you can have bingo cards with a bingo caller.
