@jeremycherfas In a way, I find it hard to believe that they could have come up like that otherwise than randomly. Remember how the iPod Shuffle had to be made “less random” because it kept doing things that didn’t look random (playing successive tracks from the same album etc). OTOH, nothing produced by a computer is truly random, since the system is unavoidably deterministic. Today’s answer would have been my first attempt yesterday, till the third letter came up pink. Today, I got it in one, with no backspaces.

@artkavanagh I agree, in my head. But my heart says no. The whole business of people not understanding random, so they have not enough sequences in numbers and so on, is fascinating. But I think @cdevroe should weigh in. He did say he was making tweaks ...
