Full guide- 01
Look at all six
One is a real photograph. The other five were made by Google's Nano Banana image models.

Zoom into the details
Pinch, scroll or double-click. Fakes usually give themselves away up close.

Lock in one guess
Everyone gets the same puzzle each day. See how you compare with other players, and how the AI did.
Learn from a puzzle you can inspect
A correct guess is useful practice, but it does not make a visual shortcut reliable. Our worked archive comparisons show the source photographs, generated alternatives, numbered observations and the limits of each check.
When you cannot count the fingers
A boxing photograph and a generated candidate both hide the hands in gloves. Compare what is visible and what remains unknown.
Study the anatomy example →A real scene with several lights
A night terrace explains why shadows do not always fit a one-light rule. Compare it with a plausible generated scene.
Study the lighting example →For an image outside the game, check its source and any available provenance as well as its appearance. Use the manual verification guide.
Why ImageGuesser Exists
We are living through a visual revolution. Generative AI models like Google's Imagen, Flux, and Stable Diffusion have reached a level of fidelity that rivals reality. For the first time in history, we cannot trust our eyes.
ImageGuesser is not just a daily puzzle; it is a digital literacy training ground. By gamifying the detection process, we help users build a mental library of “AI Artifacts”—the subtle glitches in physics, lighting, and anatomy that betray a synthetic image.
The Spotter’s Skillset
- Physics analysis: checking shadow consistency and reflection logic.
- Anatomical verification: counting fingers and teeth, and checking pupil symmetry.
- Contextual logic: identifying non-existent text or impossible architecture.
How We Generate Puzzles
Our daily challenges are curated using a strict ethical framework. Synthetic images are generated with Google's current Nano Banana image models (Gemini), so you are training against the state of the art. After you answer, each puzzle shows exactly which model made its fakes.
- Real photography
- Sourced from verified photographers on Unsplash with full attribution.
- Synthetic media
- Generated with Google's Nano Banana models - Nano Banana 2 and Nano Banana Pro today, the original Nano Banana in older puzzles.
- Review process
- Every puzzle is manually reviewed to ensure no deepfakes of real people are used.
