20/20 but under pressure I probably would of got half that. Every test calls you stupid if you need time to think it through.

First of all, on mobile pretty much every single image is cut on both left and right side, making it impossible to solve most of the problems. It's a simple change in code: just make image (or the box for it) size relative to the pages width, not to the fixed hight! Secondly, the colored shapes sequence has two possible right answers. One is what you chose - polygon, excluding circle. But also true is that rectangle is the only one being uneven. I don't know the proper term in English, but what I mean is that they can be defined by one number - like the size of the angle is the same for every angle of the figure, the lengths of the sides are the same for all sides, and radius of the circle is the same any way you look (if it was ellipses you'd have a lot more numbers).
