 Welcome to the TI-Basic Developer (TI|BD) Program Archives! We have a large variety of programs available for download, with program filtering and sorting based on genre and metadata, and will accept nearly any programs that you want to add to our archives. If you have questions, leave a post on the forums or read the FAQ. Happy gaming!

## Drifter

Drifter is a game in which you slide until you hit an object.
There are many pieces that you will come in contact with that change the direction you're going.
Collect all the +s and/or numbers 1-9 then reach the flag to win.
Drifter includes 16 levels and a custom level editor for endless hours of fun.

## Recurse

Two programs that recursively calculate the value of a function.

## Little Man Computer Emulator LMC v1.0

This program will simplify nearly any radical expression in the form of the nth root of x by removing the perfect n factors from under the radical.

This program features very fast load times, index reduction, and imaginary simplifications.

## Glyphs

A collection of most of the characters available on the TI, sorted by hex code and stored into Str0. Unavailable characters are represented by a "?". See http://tibasicdev.wikidot.com/83lgfont for more info.

This program is intended for teachers or anyone who wants to grade tests or exams. It is one of the first programs that I have written, but it is constantly being improved. Version 3.5 has a better user interface, and improved control.

## Horner's method

Horner's method is a algorithm to divide a polynom by (x-a) ( From wikipedia:[In mathematics, Horner's method is either of two things: (i) an algorithm for calculating polynomials, which consists of transforming the monomial form into a computationally efficient form;[2] or (ii) a method for approximating the roots of a polynomial. The latter is also known as Ruffini–Horner's method.])

## Flappy Bird

 Author: Robert Black; Code edited and optimized by Trenly Download: FLAPPYB.8xpNo Download Available Compatibility: TI-83/84/+/SE Genre: Arcade Graphics Platform Puzzle RPG Strategy Sports Casino Board Utility Misc Rating: 4.3

A flappy bird clone

## MasterMind 1.0

A simple, but fun mastermind game, running entirely on the graph screen.

## BlackJack

A calculator version of the famous card game: BlackJack. Graphical, fully operational.

## The Valley Of The Gnomes

After turning off Ned's hose each night, escape his yard without stepping on any Lawn Gnomes. Each night you disrupt Ned's activities, he'll add more Lawn Gnomes for you to dodge. If you stay in on place for too long you'll trip his alarm system, so you can't stop moving.

## Donut Quest

Donut Quest is a TI-Basic game of revolutionary quality. It uses no libraries of any kind, in fact, you don't need anything other than the game program to play it. On each of eight levels, you must get to (and eat) all the donuts, then leave through an exit (unless given other instructions).

## Spin Pong

A fully optimized, release ready full version of pong. Includes the ability to spin the ball and also to select a difficulty level, which speeds up the ball and makes the AI smarter on hard.

## Basic Avalanche Plus

An Avalanche spinoff.

## Grayscale Bug

This is a game in grayscale. Even more surprising is that it's in pure TI-Basic.

## Flappy Bird 2

 Author: Trenly; Credit to Robert Black for the original idea to emulate Flappy Bird on a calculator Download: FLAP.8xpNo Download Available Compatibility: TI-83/84/+/SE Genre: Arcade Graphics Platform Puzzle RPG Strategy Sports Casino Board Utility Misc Rating: 5

A remake of the previously uploaded game [[[archive:flappy-bird|Flappy Bird]]].

## Solitaire Encryption

This is the Solitaire Encryption algorithm that Bruce Schneier made for Neal Stephenson's book Cryptonomicon. Before, only a TI89 version of the program existed. This is for the TI83/84s. Give your calc some time, and eventually something will come out encrypted/decrypted. The outputs are stored in Str1 and the decryption deck is stored in ∟DDECK.
