Simulator thumbnails should prove one clear promise

Simulator thumbnails usually earn useful clicks by showing scale, reward progress, and one clear reason to start collecting.

How to use it

  • + Choose one test variable: danger, reward, or social proof.
  • + Keep one main subject and one short title phrase.
  • + Review 16:9, square, and narrow mobile crops before testing.

Example outputs

  • + Tiny starter pet beside one giant evolved pet.
  • + Empty shop beside a clear upgraded reward wall.
  • + Rare reward reveal with one main character reaction.

Common mistakes

  • + Crowding the scene with several competing promises.
  • + Using official logos, Robux icons, copied UI, or protected characters.
  • + Changing the title, layout, and central subject in the same A/B test.

Show one clear simulator action, a readable title, and a strong emotion hook.
