Each cartridge comes with an Answer/Question book.
When you start a new game, the categories at the top of the board will be numbers that correspond to categories listed on the marquee art. You will have to match the number to the category to figure out which categories are on the board. Once you choose a category and dollar amount, the game will give you a number. You look up the number in the book to find out what the answer is. You then select the correct question from 3 multiple choice options.
The problem is, by the time you've flipped through the book to find the answer and looked at your options for the question, you are out of time. Might be easier to play with a friend who can act as "host" and deliver the questions to you.
