Obby thumbnails should prove one clear promise

A obby thumbnail brief should make one action, reward, danger, or social moment readable before final artwork is produced.

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

  • + One readable obby action with the goal visible.
  • + One reward close-up with a clear before-and-after contrast.
  • + One social moment with distinct silhouettes and uncluttered space.

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 obby action, a readable title, and a strong emotion hook.
