Also I've looked at before buying one or the other website for reviews and then slammed shut. And surprise, surprise: it is one of the rare games that you unpack, short reads and can get started right away, children and adults. Stable cards in size of standard playing cards provide clear rules laying, then losgebaut with a pleasant "NERVLING" in the neck, the "mechanical hourglass". With proper design, the game round is ok, quickly overturned the tower and built next card specification. There are simple tasks there, but also some tricky, so that children and adults has relatively equal opportunities. And in the end the overall gameplay is here greater than losing a single player. It is not a game that you can play for hours, but with us it has not always made for a serene hour of play. Only four stars in durability because of the timepiece, because I'm skeptical about how long the hold by the constant pulling. Thoroughly recommended (by me)!
