This game will actually suit all the family, from the moment we can count up to 10. Very quickly the batteries are increasing and we must be quick and defficience to achieve post cards before his neighbor.
The game can easily handle 30 minutes. I suggest you play it in combination with another game, because a risk on that evening to make it monotonous.
The downside is also a bit that everyone plays his part, one quickly feels lonely and laughs are then not legion.
