can anyone tell me how this works?

There's already a thread about it from a couple of weeks ago, Donna (I'm sorry, I don't know what it's called). Basically any answer is divisible by nine, so the icon by each multiple of 9 is the same. It changes each time you do the test which makes it seem more spooky, but actually that's just the grid changing.

ok cool, thanks :-)

Haha! Yes, I was the last sucker who started a thread about that seemingly perplexing little piece of shockwave...

Here 'tis

I am dumb. Please tell me how this works...
