Amazon.com description: Product Description: Comical, color-illustrated stories come alive with accompanying rollerball games set on heavy board pages. This Rollerball Racers book contains three two-part games in which a meandering path is enclosed beneath a see-through plastic window. Inside each path is a tiny, ball-shaped bead--the rollerball--which kids manipulate by tilting the book one way, and then another. At both ends of every path is a hole that's just large enough to allow the rollerball to drop into it. When kids succeed in sinking the ball, they turn the page and see where the ball has appeared for a new game on the thick board page's opposite side! This book combines racing games and silly stories, boys and girls join Archie the Astronaut on his outer-space adventures. Rollerball Racers make great travel companions on car trips.
