“Crapong” (what a name!) is a ping-pong game where you control a paddle and the AI controls another. Fairly simple, right? Well, in “Crapong,” you also have guns. Yes, I said guns. You basically score points either by shooting the AI paddle, or getting them to miss the ball. Since the AI was programmed to never miss the ball, you basically can only shoot it. However, it has multiple speeds and can be pretty intense at times. I liked having this on my calc because it was small, yet had a certain fun-factor that kept me coming back once in a while. I suggest this program to anyone who cannot keep attention in classes, but don't want to spend too much time from their studies.
