The 4th one of the yellows was a total guess. I worked out the connection for blue, but only knew 2 for sure and a vague hunch for the 3rd, so again, the 4th was a complete lucky guess.
Had absolutely no idea what purple's connection was.
Today's was definitely a lot harder than my single mistake would imply!!
