I played this game when I was a kid at a College For Kids camp at the local community college. It was on their mainframe, green screen monitors and every turn printed out on green bar paper. I later found code that created a similar game published in a book at the local library. I spent hours typing in that program ... and discovered a bug in the code. It was my first time debugging a computer program. Once I fixed it, I played it for hours and loved every minute of it. I shared the debugged program with my classmates and we spent hours during rainy recess playing it.
