Once upon a time, some guy named 'Stu' created a cool QuizBox game and put in on the Internet.
So, CCDGames developed some QuizBox games for Catholics and posted them here (click here).
Download and unzip to a folder of your choosing. Then click on the QuizBoxes.exe file. Pick the number of teams, then the names of the teams, then go into the "quizzes" folder and pick the quiz you would like to run.
Feel free to call me (Alan) if you have any questions.
