Good but tiring

Esteinmal ahead: The game is good!
It's fun and is opened by the rules here as the Ubongo Extreme also. (Wers not know, here's a quick summary: One just needs to three-dimensional) (here by means of predefined blocks covering a printed board on empty field and on the whole time).
The game material is attractive and as usual with games Kosmos also quite high, I think.
We come to the "but":
It's just very difficult.
The simple Ubongo can still score with a lot of gameplay and maintains easily.
The Extreme version is already more sophisticated and demanding, but also her balanced by Spielpaß / concentration ratio.
The 3D version but already falls into the category of "exhausting"
You needed (I) another 2-3 games to notice in Extreme in mind that the game is anything but relaxing, so it falls in 3D already on the first lap.
Do not misunderstand: I like to tickle the brain has the game totally happy, but it's just not a simple game in which you can act without much thought. There simply sucks zuvel "brainpower".
Here it is not on tactics or scheming to, but on spatial cognitive abilities or the chance (of a here but sometimes just easier to work with).
As with anderne versions also have been sometimes simply the impression that the puzzles are inextricably what one then usually neighboring the one which then throws with the words "Do you, will you?" disproved within a short time. Only here there is a table of solutions. And that's just as well!
We had a thing none of the 4 Players out took place and of course all hewed to the solution on the head.

Conclusion:
Ubongo 3D is definitely a must for all lovers Ubongo.
It's just only tricky and even more exhausting and, indeed, sometimes even more frustrating.
But it is also simple: GOOD
