Bought as a gift for Christmas. This game has really aroused curiosity and amused the young and adults. However I removed two stars because unfortunately there are defects (plastic burr) that prevents the path of the ball, so it is a puzzle that will never be solved properly because the ball can not take certain roads (including lorsquelle must pass through holes) the full itinerary will be impossible to achieve. For the price the least we would have a perfect game!
