Features

This game is "Guess my Rule" a Math concept usually covered in Pre-Algebra (around 8th Grade). The object of the game is to guess the "Rule (linear function) by entering in several "In" ("X") values and having them resolved to the "Out" ("Y") values. You're job is the find out the rule which governs this.

Space

497 blocks RAM memory

Using

Difficulty

Enter a difficulty to play. Note: Difficulty is cumulative, so you may get an easy game, even if you select "5"

Difficulty #	Difficulty
1	Really, Really Easy
2	Really Easy
3	Easy
4	Medium-Easy
5	Medium
6	Medium-Hard
7…	More difficult…

Enter "In" Values

Now you get to enter "In" or "X" values. These "In" values will be run through the "Rule" (linear function" and the result will be displayed. The number of times you may try "In" values is equal to 2 plus the difficulty number you typed in. Note: You can't try entering "0" or "1" as the "In" value because that will make guessing too easy!

Guess Rule

Now you have to guess what the rule (linear function) was. It will follow the pattern "Ax+B", where "A" is the slope value (what each "In" increases by), and "B' is the y-intercept value (the "Out" when "In" equals 0. If your right, it will tell you, if you're not, guess again.

Restricting Guesses Code Change

To make the game even more difficult, by making the number of "In" tries fixed, instead of variable with the difficulty, you need to change the PRGM code.

Open up the code editor, by going hitting [PRGM] [(Right)], and selecting "GUESSRUL". Then scroll down to find the line "D+2->G". Change "D+2" to the number of tries of the "In", for example: "3->G"

Standard Info

Requirements

A TI-83 Plus, TI-83 Plus Silver Edition, TI-84 Plus, or TI-84 Plus Silver Edition (Not tested on other versions)
A cable to connect your calculator to your computer.
- The TI-84 Plus and TI-84 Plus Silver Edition came with the cable.
- Everyone else needs to purchase at Wal-Mart, Best Buy, or anywhere, a TI Connectivity Kit with a silver USB to calculator mini-jack cable called the "TI-GraphLink USB (silver)."
- (More information on choosing cables)
The software to make your computer talk to your calculator. (It should have come with your calculator or cable)
Free space on your calculator.
- 16,384 blocks for APPS
- 303 blocks RAM for SNAME PRGM
- ~100 blocks RAM for simple PRGMs
- ~500-1000 blocks RAM for complicated PRGMs like games

Install

The TI GraphLink cable and TI-Connect software

Have installed TI-Connect (the software which came with the cable/calculator)
Download the PRGM "SNAME" which is required to be on your calculator for all PRGMs. APPs like "FERRIS", don't need SNAME.
Download the PRGM (.8xp) or APP (.8xk) file to your computer. Save it somewhere.
After downloading, find it on your computer. Right click and hit "Send to TI-Device"
TI-Connect will open. Choose your calculator and wait for it to transfer. Make sure you have enough free space on your calculator.

Run

Go to [PRGM] scroll to the program's name. Push [Enter] to select it and then [Enter] again to run it. You will see a splash screen. Hit [Enter] to continue.

Exiting

To exit the program, hit [On] key and push [Enter] or [1] to quit.

Removing

To delete a PRGM or APP, push [2nd] [MEM] [2]. Then push [7] for a PRGM or [ALPHA] [A] for an APP. Find the one you want to delete and hit [DEL] [2].

Error: Memory?

If you are getting the error when you want to run an APP, you don't have enough free RAM memory. You need to archive a PRGM. Do this by hitting [2nd] [MEM] [2] [7], finding the PRGM you want the archive, and hit [Enter]. Note you need to unarchive it before you can run it again (Unless you use Mirage or similar OS to run archive PRGMs.)

Note

Note the program might set your calculator in degrees mode, change the graph settings, turn off floating (rounding), and/or overwrite variables. After running the program, make sure your calculator is back the way you want it before doing other things.
