The book has hundred puzzles. Each puzzle has twenty vanity license plate clues listed below the puzzle. License plates can have no more than seven characters (letters and numbers) on the plate, but they can have less. Vanity plates can be made up of letters and/or numbers that make a name or a phrase that the owner feels is funny, a good point about the car, maybe bragging about the car, something about a family member or something to be proud of, and many things others won't understand.
First the puzzle solver must decide what the clue letters and numbers are saying. An example of a clue is (ICUNVME) the puzzle worker then must find that phrase in the puzzle and circle it or draw a line through it. When a puzzle person finds and marks all twenty of the plates in the puzzle and is done, they will get a prize. The prize is the good feeling of solving the puzzle without looking at the solutions at the end of the puzzle book.
