As I have a working knowledge of SQL this was very simple but my friends who use it sparsely in their financial jobs had a blast racing each other.
This type of gamification is awesome and as someone who loves coding but doesn't find Sudoku's or whatever very enjoyable, I would love a place I could do little coding challenges like this in break times!
Anyone know of any? I'm thinking "Escape Rooms" via coding could be a big thing!
