Here's one of my older Ti-Basic games, Numb3rs. I decided to upload it because it's pretty fun, but also to show how bad of a programmer I used to be.
The first version is from when I first made it, when I had just figured out what a For( loop did. I had yet to figure out While and Repeat loops, though...
The second version is the version to play, and it's pretty fast and fun. Enjoy!
Please note that the version in the screenie is the New one (even though it's from 7/23/09). If you want the game for playing, download the one that says New.
