I? Smart?

I think that many habrovchana have nowhere to use their intellectual abilities.
Therefore, I suggest that users play the next game. I invent a puzzle from the field of natural sciences, for the solution of which it is unlikely to need more knowledge of school, but I will need the ability to think logically.

It seems to me that it should be more interesting than a sports CPG.

If people need it, I can start right now.
