The player can drag their finger in any direction to turn the picture. It is in 3 dimensions, thus the way it is projected on a particular plane will change as you turn the image. Your job is to align the pieces so that they create a coherent picture. Note that the solution isn't always in the same orientation as the original image, you can in theory solve it upside down, sideways, and so on. The level name and image preview are decent hints for what to do.
