ABOUT THE GAME

About Difference Atlas

Difference Atlas is an observation puzzle with original geometric illustrations. Compare two pictures and select five details that have changed, from a cottage door or cloud to a sign or small landscape object. The campaign contains twelve chapters across four illustrated scene families, with no time or mistake limit. Pause, ask for a hint or come back later using the save stored in your browser. For a shorter challenge, the daily expedition gives everyone the same three scenes on each UTC date. Find fifteen differences within three active minutes, before making five mistakes. Hints and restored games remain playable but produce local results only. Zoom helps with small screens, keyboard controls offer an alternative to pointing, and all seven languages use the same game build. Global ranking is not available yet.

How to play

Choose Explore the atlas or continue a saved journey. Compare both pictures and select a difference in either picture. Find five differences to unlock the next chapter. Use 2× zoom for smaller details on mobile. The daily expedition ends after three completed scenes, five mistakes or three active minutes.
