perhaps only computer science
Do yourself a favor – make 4 friends, and grab a copy of the board game “Clue.”
What is sold as merely a game of simple elimination is quite intense when you’re older. A bunch of us got together and played and we went Beautiful Mind on it – the effect only embiggened by the fact that you only get a little tiny piece of paper upon which to make notes.
I think it was Crystal who actually wrote down (somehow in such limited space) every supposition made, and who provided evidence.
Seriously – Clue, go pick yourself up a copy.
