#70501  Outta Gas! is an entirely new type of slide puzzle. It's three-dimensional, has incredible detail, and features a special flip-up building that covers the traditional open space. The end result is a complete miniature gas station with vintage cars, gas pumps, office, and a service bay with a floor lift, workbenches, and oil drums inside. After you've arranged the cars and pumps to solve the twelve challenges on the back of the puzzle, you can make up your own and challenge your family and friends!
