From the publisher:
"Be the first to reach the finish line by climbing rickety ladders and avoiding slippery slides!

A truly unique 3-dimensional version of the classic children’s game! Players move their marbles along the board based on the roll of the die. If their marble lands on a space with a slide, gear, ladder or other challenging obstacle, they must test their skill! Contents include: 3-D game board, 4 colored marbles, number die."
