Moderation basics

  • All uploads are reviewed against Roblox's Community Standards.
  • Don't promise things your game doesn't have — misleading thumbnails hurt retention and can be removed.
  • No real-world personal info, off-platform links or QR codes.
  • Keep violence and horror within your experience's maturity rating.

Order matters

The first thumbnail in your list is the one most players see first — put your strongest concept there.
