Just press the green flag to start; everything else should be easy to follow.
This project is based on the binary number system. (My father used cards like these to play the guess-the-number game with me when I was young; thanks, Dad!) I wrote the project to help my 6th-grade computer science students think about algorithms. (Once they understand how I can "guess" their number depending on which cards it is on, they need to figure out how to formalize that process and make it into an algorithm that can be used to write a program.)
