Different settings, the same clear rules.
Choose a setting you enjoy, compare its two pictures and look for seven changes. A collection’s puzzle count tells you what is ready to play today.
Purpose-built scenes
Each world defines the objects, composition and kinds of differences that belong there.
Source-aware information
Real-world claims are separated from fictional lore and require a source trail where accuracy matters.
Review before publish
AI may help generate concepts and imagery, but playable differences and factual copy remain behind review gates.
