I think the third one is easiest on the eyes.
But the colors in the first go best with the plasticy look to the interface.
I would change the yellow dots on the first one to a dark shade of purple perhaps. They draw your eyes away from the questions.
In all the deisgns, the horizontal lines across the middle created by the sharp transition from black mess with your eyes. I would try to fix that by adding a darker indentation around the black area to reduce the contrast, or making the black area have a color instead.
I would consider making the yellow buttons int he first image the same green as the lower bar. I might try making them a slighly darker shade though to indicate they are a seperate part opf the interface and to make them appear to be in the background more as if they are less important than the other interface elements, which they are if you are in the middle of playing a game.
