How do I put games on the TI-NSPIRE CX CAS?
Most of the games will give a .tns and a .lua file. If you want to upload the game into the calculator, you need a software called TI-Nspire CAS Student Software. This is obtainable through installing the software via the CD provided. Once you have the program, click on the right-most icon in the section called Documents Toolbox. Here you should see two windows, one showing the computer, and one showing the calculator (you must connect the calculator to the computer via wire) On the desktop window, find where you put the .tns game files, right click them, and click copy. On the calculator window, go to MyLib, then go to the file where you want to put it. Then click the icon that looks like a gear in the top right of the calculator window. A drop box should open. Click paste. If the transfer was successful, the screen on your real calculator should pop up a random message saying the name of the file you want to transfer and where you transferred it. There! You now have the game in your calculator. If you want to play it, go to the home screen, then click My Documents (second option on the right), find the game, and click it. PS my name is NOT John its just a fake so I could answer your question.

If you have it's custom firmware, you can just download that, install it, then directly install the game into it. Links below: http://www.ticalc.org/pub/nspire/basic/games/ HAVE FUN!!! :D
