Space builder, observation and speed game, from 8 years old

About Space Builder, from BoardGameGeek:

GAME OF OBSERVATION AND SPEED OBJECT: be the first to build your space city, following the map instructions. All players place a board before them facing the same way and take a set of building cards. The game is played in multiple rounds. In each round, a “map” card is turned over and placed face up in the centre. Players play at the same time, building their space city with their “building” cards according to the map instructions. Warning! Players may not turn the map card to face a different direction. You have to be fast and observant to avoid construction mistakes! +++ A very fair game: the winner of the round has to play one more card than the other players in the next round! -description from the publisher
