In the end, I had almost as many "THANK YOU" that there were parts (102!)
I spent a great afternoon (it is not always selflessly gifts ...) and I am confident that this game has an almost unlimited life, probably from 4 to 177 years (just need to hide past a certain age)
One regret, we spent some time too lazy to take the ball to put them up ... it lacks an engine!
Will have to order another box:
Quercetti - 13/6575 - 180 Circuit De Billes
PS: I did not share with Quercetti :-)
