3 small trucks, and 10 brightly colored, irregularly shaped, plastic puzzle pieces. Trucks have wooden frames and carry transparent containers on their backs. Object of the game is to fill up one or more trucks with a specific set of puzzle pieces. But no part of any piece can stick out above the boarder of the containers. The transport containers make it over clear if you have been successful or not. Each challenge shows you which truck and which pieces are to be used. The beginning challenges involve only one truck but the more difficult puzzles may have 2 or 3 trucks and provide no indication of which part is meant to go in which truck. Playful and engaging way to exercise, problem solving skills, spatial organization, perseverance and hand skills, while fostering ability to analyze information and "think outside the box"!
