Real or Fake?

Twenty micrographs. Slide between fake and real, then go on.

Rules

You see 20 micrographs, one at a time. You cannot go back to an earlier one.
Every image is real or fake on its own, with equal chance. The round is not forced to contain ten of each. When an image is fake, its model is picked at random, evenly across the models.
One slider. The red end, −1, means you are sure it is fake. The green end, +1, means you are sure it is real. The middle means you have no idea.
An image scores your slider value if it was real, and the opposite of your slider value if it was fake. Sure and right is +1. Sure and wrong is −1. The middle is 0.
Your result is the average of those 20 scores, multiplied by 100. A perfect round is +100. Leaving every slider in the middle is 0. Higher is better.
At the end you see that score, which images were real or fake, your place, and the name of the person currently leading.
