This is a German game; I will provide rule translations.
The theme is architecture in the stone age. One player of a pair acts as the architect who sees a card with the blocks in a certain order. The other acts as the builder who doesn't see the card. Trouble is, language hasn't been invented yet.
So the architect has to communicate to the builder exclusively by means of 6 groanlike calls in combination with 6 possible moves (hands up, stamping feet etc.) to tell the builder which blocks to pick, whether or not to rotate, and where to put the block. Both the architect and the builder have a card that depicts what the various moves mean, and what the 'words' mean.
If the builder does an action right, the architect gives him a light tap with the bludgeon on the head. If he's wrong, he gets two taps on the head.
The object of the game is to be the fastest architect/builder team to construct the pictured building.
