Summarize the following:
You can move your token in any one legal direction: toward a wedge or toward the center when on a spoke, clockwise or counterclockwise when on the outer wheel. You can also move from a spoke to the outer wheel or from the outer wheel to a spoke. However, you cannot reverse direction in the middle of a roll. If you land on a "Roll Again" space, roll the die again. (You can move in any legal direction, including the opposite direction from your previous roll.) In Trivial Pursuit, you get to move again if you give the right answer. You can keep rolling, moving, and answering questions until you get one wrong. Just keep in mind that the questions you answer must correspond with the color space you land on. For example, if you land on a blue space, then you must answer a blue question.  If you are in the center space and have not earned all six wedges, you may answer a question in any category of your choice. In the 25th Anniversary Edition, the question you must answer is also determined by the roll of the die, as each box contains questions for a single category. The higher you roll, the more difficult the question you receive. You can earn pie pieces by correctly answering questions, but you can only earn a pie piece when you are on a pie space. These spaces look different from the others on the board because they show an image of the pie token with a wedge in it. For example, if you land on a brown wedge space and answer the question correctly, then you would earn a brown pie piece. When a player gets all six pie pieces, that player may begin moving to the center or the board. You must keep rolling and moving each turn as usual until you get to the center space on the board. You need to roll the exact number of spaces to get to the center space. Keep in mind that you may spend several turns coming up short of or overshooting the center until you land on it. When you get to the center space, your fellow players may choose any category and ask you a question from that category. If you answer this question correctly, you win the game. If you miss it, your turn ends, and play passes to the next player or team.  The other players may not look at the questions before choosing the category. They must select the category without looking at the card and then read the question. If you miss the question, you will have to roll again during your next turn and try to answer a different question when you get into the center space again.

Summary:
Roll the die and move your pie the number of spaces indicated on the die. Move again if you give the correct answer. Earn pie pieces if you land on a wedge space and give the right answer. Keep playing until someone has all six wedges. Answer a question in a category chosen by the other players.
