Wharf Minder

As you can see, this is a time to show ingenuity.

As dock master, you will need to direct the boxes, which are marked with different weights, and place them on the sides of the boat. Have the same number of boxes on both sides and the same total weight -- why do that? Probably afraid of capsizing. In fact, here, the boat never capsize, as the caretaker's challenger, you can never lose; The only thing you need to do is to do it in as little time as possible and surpass yourself.

Simple, but not very simple.
