In Looking for mistakes, the player must find the difference between two images A and B. There are two different methods in which the images are displayed to the user, which are called "Change" and "Movie".

For "change" the game swaps between the two images with a small break in-between. Due the the small break where only a completely grey image is displayed, the human eye can not track the differences as easy as if the images would swap directly. In real world the brain tries to ignore the effect of a blink of the eyes[1], and according to our experience a real objects can not simply disappear during that time. Similar to the effect of blinking, this also happens with the grey screen break, which makes the difference hard to spot.

Selecting "hint" makes the break between the images faster, and "answer" allows the user to switch directly from one image to the other with a mouse click, which helps to spot the error immediately.

For "Movie" the game is very slowly blending from one image to the other and back. An indicator at the lower left shows, how much of each of the two images is displayed: If the red spot is at the left or right side, image A or B are displayed directly. If the red spot is somewhere in-between, a corresponding mixture of the two images is displayed.

Selecting "hint" makes the blending between the images faster. "answer" allows the user to switch directly from one image to the other with a mouse click, which helps to spot the error immediately.
