What creates a good long session puzzle
A strong long-session puzzle needs enough detail to stay interesting over time. That can come from architecture, subtle color gradients, layered landscapes, or more complex artistic composition.
If the image is too simple, the session may feel slow for the wrong reason. If it has the right density, the longer solve becomes the point of the experience.
