The game promotes spatial thinking, because you only once (similar to Tangram) must place three or four different shaped parts in a given frame before taking the jewels. Even if one thinks that it is not possible: it always works!
If necessary, you have to help at the beginning of the other a little more, who then at the latest the next time out and are faster than you. Or you are waiting with the gemstone take until all (within the given through the hourglass time) their laying planks ready have.
One round is played in about 20 minutes so that you do not sit forever at play, but prefer all over again plays and therefore the chances are again redistributed.
It's also nice that this is not always the one who wins, who has the fastest its tablets filled with the forms, but also the slower players have a good chance.
Definitely recommended.
