From the box:
"Will you be the first Cinderella to go to the ball? Collect 5 different cards and the Fairy Godmother will help you transform your cards to get ready for the ball. If you collect the invitation, the coach, the horses, the footman & the coachman as well as your ball gown, you will be the Cinderella who goes to the ball!"

Players move Cinderella pieces around a board, in the center of which is a glass slipper on a cushion. Land on the fairy godmother squares, press the slipper and it may transform the humble cards you have collected (mice, pumpkin etc.) into the things you need for the ball.
