After about a month of trying to figure out binary-based puzzles for my pong roguelike (the game takes place inside of a computer kernel), I think I have settled on a new monster I'm going to refer to as binary-sudoku.
I wanted to get feedback on what my fellow GameDev.net'ers think. I see some limitations to it, but I if visually abstracted right it'll be very entertaining.
Nice! Gamification of computer science education! Should be mandatory in game programming classes 
what is the purpose of putting the numbers on both sides of the rows? in all your examples they are the same, can they be different? I am assuming that they are the results of doing the operations, because it comes out in your examples.
I also think there is already a game called binary sudoku, though the rules are different then this.
