About Parity
Find the correct pair in a 4 by 4 matrix of ordinary circles ;)
Rules :
1. If circle is red, click on the farthest diagonally opposite circle.
2. If circle is blue, click on it.
3. If circle is green, click on its lateral image (fold the matrix along its vertical center then the circle overlapping the green circle is its lateral image)
4. You have to click on the correct corresponding circle in only 1.5 seconds to get a point ;)
Let's see how far you can go......................
