Ah, so they modified that slightly to stimulate your brain
I done a quick search about the right and left side of the brain and according to
this site each side is responsible for...
Left Brain: Logical, Sequential, Rational, Analytical, Objective information and Examining parts of objects.
Right Brain: Random, Intuitive, Holistic, Synthesizing, Subjective information and Looking at objects as a whole.
So I guess this game is looking at random, intuitive and looking at things as a whole.
