Interesting literal take on the theme. I feel as if the concept is a little flawed. Balancing the weight is not difficult, and actually gets easier over time (e.g. adding 3 kg when there's already 100 kg on each side is not gonna significantly tip the scale). But then, if the challenge is not in balancing each side, then the point of the game is to pack the ubicados as densely as possible in the size available. Which begs the question: are the scales important for that? There isn't any consequence for dumping an ubicado you don't want (which also makes packing compactly easier). Overall I feel the need of an additional twist to make the concept interesting.
