Build a Lego tower via your helper

Task brief

The actual text of the task brief is not known. The text below is paraphrased based on information disclosed in the episode:

In each box is a Lego tower that Atle has built.

You must build a tower with the same number of bricks, but you will not see the tower yourself.

You must choose a helper who will look in the box for you.

Then you decide how high your tower should be, and your helper must build it.

You may not choose a helper who has already been selected.
