Just to test my opponent's predictions, I wrote a quick script using a real CSPRNG to give me left/right instructions. As expected, after a hundred moves I was way ahead. The interesting part was this: I had the script just run a loop with a short delay between outputs. I started with a little under a second, and my brain/fingers kept trying to anticipate the next element. Often incorrectly, making my input predictable by the site. My fingers were just twitching to press a key. In order to "win", I had to set the delay to 1.2 seconds, physically lift my fingers off the keyboard, and spend a little bit of effort reading each choice to make sure that I was actually following the real random instructions. My brain just struggled to cope with the lack of pattern.
