Correct, this is a design problem, but no one's pointed out what the specific problem is: The "Instruction" that most people perceive is the title of this post on HackerNews. By the time you actual visit the site you ALREADY have an idea of what it's supposed to be about, the colors draw your eyes to "Here's how you can tell your score, press here to start" and skip the fine print entirely. People MIGHT skim the "fine print" that is the actual instructions with key details, and what do you read when you skim? The first part of a paragraph/sentence to establish a subject and action. And what's the First part of that sentence? The same thing the title of this post told you. "Oh, yeah, I already know this" Skip to the pretty colors telling you how to score your guess and start the game. EDIT: Also, the UI after you click through to start also assumes the user read the instructions, instead of trying to organically guide them to the same conclusions. /EDIT. Cue so many people wondering how they could miss something laid out so clearly in front of them.
