An operating system
“An operating system” is a question in OnlyClick, and our answer book knows 87 answers to it. Most people go straight for Windows, Android or iOS, so those barely lift the rocket. It is a fairly short list: only 29 answers sit in the two rarest tiers, so reaching one takes real knowledge.
What you remember from school is what everyone remembers. The rare answers come from the back of the textbook. You will find it in stage 28, “Net Ninjas”, of the Science mission. The first stages of every mission are free, and later stages come with the full mission.
