How it works
The interaction stays simple; the system behind it keeps the differences intentional, replayable and reviewable.
Compare the two full-resolution scenes side by side.
Correct clicks glow and sparkle so the feedback feels satisfying.
See your completion result, then choose another scene or replay the current one.
Move from a single puzzle into a themed world, collection or progression path without changing the core mechanic.
Why Spotly
Search the shelves of a coastal room, the flowers in a harbor market or the decorations of a snowy village. Replays change the selected differences so familiar scenes still need a close look.
No account wall between the player and the puzzle.
Look for everyday objects in Cozy Life, street details in City Stories and seasonal decorations in Winter Worlds.
Comfortable tap targets, clear feedback, and a responsive layout from day one.
Each scene has five to seven reviewed changes. Tap the changed object in either picture; hints can guide you when a small detail is difficult to find.

Our approach
A missing object, a different colour or a changed small detail should be clear when you find it. Each new pair is checked for unintended fragments, distorted neighbors and matching click locations before it joins the public puzzles.
AI is useful for concept exploration, original artwork and production support. It is not treated as a factual source or as an automatic publish button. Real-world information needs evidence; fictional material is labelled as fiction; playable differences need visual and coordinate review.
That process is intentionally visible. Players should be able to understand who publishes the content, how it was made and why a page exists.

FAQ
Spotly looks light and simple, but behind it sits a real daily-game system.
Spotly is a browser-first spot-the-difference game organised into visual worlds. Each reviewed scene can return in multiple difference combinations, so replay is part of the design rather than an afterthought.
No. You can play as a private guest. An account is optional and is used to keep verified progress, points and unlocks available across signed-in devices.
Spotly creates illustrated scenes with AI assistance. Each published pair is reviewed for clear differences, intact objects and matching click areas. Read the editorial policy to learn how images are checked.
No. AI can propose concepts, images and draft copy, but a generated result is not treated as a verified puzzle or a factual source. Review gates control what becomes public.
Worlds group scenes by setting and subject, such as quiet interiors, street markets or winter villages. Open a world to see its available puzzles; some themes are still waiting for their first reviewed scene.
Real-world cultural, historical, scientific and place-specific claims require a source trail before publication. Fictional worlds and stories are labelled as original Spotly fiction instead of being presented as facts.
