It's really not, though. I'm not a programmer, but I can solve Fizzbuzz and Hello World in Ruby, and I still wouldn't know where to start with a bingo card creator.

I could manage to randomly reorder a series of words, but putting them into a nice graphical layout and programmatically making sure that short words and long words both look okay without anything getting squished or cut off is already beyond what I can do without hours of research. And that's as a geek who's generally interested in programming. My mom, who's far more likely to need bingo cards, panics every time I minimize a window.

And if you don't know how to get fire or bread, or how to make bread, or how to get bread, then you don't know how to make toast.
