The TI-84 Plus CSE is largely incompatible with programs designed for the monochrome or CE calculators, but BASIC on the CSE is compatible with the CE so most programs designed for either will work correctly on a CSE and some monochrome BASIC programs will also work correctly. Most assembly programs require Doors CSE 8 to run, as do some BASIC programs.

Reversi, the classic tile-flipping game. Only 1397 bytes, this game offers both
Categorized under:
a basic computer and a two player game mode!
The object of the game is to have more of your pieces on the board than the
other player. The game starts off with two of your and two of the other player's
pieces in the middle of the board. Each player then takes turns placing their
pieces. You have to place your tile next to one (or more) of their tiles. All of
the pieces that are in between your placement and another of your tiles get
"flipped," or turned into yours. Once the board is filled, the game ends and
whoever had the most pieces wins. Sometimes, there might not be an eligible
move that you can make. In that case, you must pass your turn. The cursor is
colored the same as whoever's turn it is. -

This is a dumb program I made to annoy my friend who hates the Jump In The Cadillac song. Press enter to make the lyrics duplicate. Press on to stop the program.
This works perfectly on the TI-84+ CE and the TI-84+ CSE. It also works on the TI-83/84+, but some characters will go past the screen (You can modify it to work just fine though).

This is a puzzle game where you are a caterpillar, inspired by the game Snakebird.
Categorized under:
In each level, you have to eat all of the fruit before making it to the goal. Each
fruit makes you bigger, and because caterpillars cannot in fact phase through
themselves, you have to be careful not to get stuck! Also, caterpillars are not
immune to the force of gravity, so you will fall down if you aren't standing on
something. Oh, and spikes. Did I mention the spikes? Yeah, those will kill you too if
you're not careful. Although the earlier levels are somewhat easy, they get a LOT
more difficult later on, providing you with plenty of playtime. There are 25 levels
in total, and a level creator. If you create a cool level, send it to us and we could
include it in the next game! -
This program demonstrates coloring the foreground and background of homescreen text using Doors CSE 8.x's det(12) function. It generates a version of the classic Matrix animation, falling green characters on a black background. Requires Doors CSE 8.0 RC2 or higher to run.

This is a tech demo showcasing how dithering allows TI-BASIC programs to display up to 225 colors instead of the usual 15. Input a seed for the randomizer, and watch as this pure TI-BASIC program draws squares of up to 225 different colors.
This technique is a bit too slow to be practical for use in games, but it looks cool.

NORMCHK is a program for checking if your data follows a Normal (Gaussian) distribution!
Note: This Normality check relies on finding the correlation coefficient of the Normal probability or quantile (a.k.a "Q-Q") plot of a variable. There are MANY ways to assess the Normality of a sample distribution; this is one of them.

A QR Code generator written entirely in TI-BASIC!
Str1 is encoded into a byte-mode, error-corrected QR code, from the smallest 17-byte code (generated in as little as 30 seconds) up to 321 bytes, the largest that will fit on the monochrome's screen.
The README and annotated program source file go through all the steps of data encoding, calculating Reed-Solomon ECC, and drawing the QR Code.
Runs on all 83+/84+ calculators, color or monochrome.

README
Hi Cemetech, this is my first upload. This program was written by me in TI-BASIC, and it can work with the TI-84+ line of calculators. I may try to make it compatible with TI-83 later. It can be used to help with calculations in chemistry around Mass, Volume, and Density and % Error. It has a simple menu, and can calculate the following with simple Prompt functions:
- Density (Finding the density of something by calculating through Mass/Volume)
- Mass (Finding the mass of something by calculating through Mass/Density)
- Volume (Finding the volume of something by calculating through Mass/Density)
- Finding Volume through the Initial Volume and Final Volume
- % Error (Finding the difference between your experimental value and the accepted valueNavigating through this program is simple, you can press the number corresponding to the option in the menu, and use the option to calculate something. After your calculation is finished, it will say "press enter" and you will then be sent back to the main menu after pressing ENTER.
I use it for chemistry class, but I highly advise that people who use this, will still study the equations, and not completely lean on this program for the answers. It is supposed to help with getting work done faster, but it should not be used to do everything for you. It helps me in finding the mass, volume, or density of something after measuring its mass or final/initial volume (which would then give me a volume of the thing I am measuring).
Update:
Categorized under:
Fixed a calculation error I made. It used to be division, but it was actually multiplication for finding Mass and Volume through density with mass/volume. Sorry for the mistake. -
This program takes list L1 and gets various information from it (e.g. mean, median, mode, range, IQR, outliers, etc). Great for Algebra 2.

A World Atlas for your TI-84 Plus CE! (and a stripped-down version for the CSE and monochrome 83+/84+)
Navigate a world map, zooming in on continents, and selecting a country from different subregions.
See the country's Name, ISO 3166-1 code, Capital, Population, and a color rendition of the country's flag!
Data for 250 unique countries is included. For monochrome 83+/84+ calculators (and the CSE), a stripped-down version with no flags or map is available.
Pure BASIC, no libraries or shell needed.

ELDROW is the smallest (13498 bytes) 5-letter guessing game in the Archives, and the only one compatible with Monochrome and Color TI-83/84-series calculators (including the 83 non-plus, memory permitting).
There are 2331 randomly selected unique words waiting to be guessed!
6 guesses, 5 letters, and hints of -, +, and = indicating not present, wrong location, and correct letter.
Used letters are tracked on the right-hand side for reference. The game does not check that guesses are valid words.
README.txt lays out the controls, the logic, and there is an annotated source code for learning the algorithms behind the gameplay.

POMODORO is a Pomodoro Technique Timer for TI-84 Plus CE, CSE, and TI-83 Premium CE
The Pomodoro timer breaks time up into Focus and Short Break sessions, with the occasional Long Break.
By default, POMODORO cycle has 4 Focus sessions of 24 minutes each, with 6-minute Short Breaks in between. After 4 Focus sessions, a 15-minute Long Break is due, then the cycle starts again.
In the main Timer Screen, the time remaining in the current session ticks down. When less than 10 seconds remain, the screen flashes to alert to the changing session.
The session tracker near the bottom of the screen points to the current session, indicating (F)ocus, (S)hort Break, and (L)ong Break.In the Edit Screen, the duration and type of each session can be edited, along with the number of sessions in the cycle. The cycle's session duration and type data is persistent, stored in custom list PMDR (must remain in RAM).
This is written entirely in TI-BASIC on-calculator. It does not require any shell or external libs.
