This game is version 1.0 of my fist game, Pick Num. In this game, the calculator will pick a random number and it is your job to guess it.

PIKNUM10 Digits.png

Choose how many digits to play with. The more digits you play with, the greater the difficulty (each extra digit increases the difficulty 10 times). My favorite is "2" because games take about 5 turns.

Difficulty # Numbers Are Between
1 1 and 10
2 1 and 100
3 1 and 1000
4 1 and 10000
X 1 and 10 to the Xth Power


PIKNUM10 Guess.png

Try and guess the number the calculator has. The calculator will tell you if the number it is thinking of is higher or lower than your guess. You may guess as often as you want until you guess the number.


How I Play

I start by guessing the number in the middle of the allowable range. For this example, assume I entered "2" as the difficulty, so the calculator is thinking of a number between 1 and 100. The number in the middle is 50. I try that and the calculator says "Try higher". Now I know that the number is somewhere between 51 and 100. The next number I try is 75 (right in the middle of the allowable range). In such, I am not merely guessing, but methodically narrowing down the possibilities, in order to find the number in the least number of guesses. It says "Try higher". All right, the number is between 76 and 100. Rather than try a weird number like 87, I try the next multiple of 10: 80. "Try lower". Now I know the number is 76, 77, 78, or 79. I try 77, which is somewhere in the middle. "Try higher". All right, it is 78 or 79. One in two chance. I just go with 78. "Try higher". Darn; it's 79.

PIKNUM10 Won.png

Your score is merely the number of digits you play. The number of guesses you made has no affect on it. Each round you play adds the number of digits you chose to your score.

Standard Info


  • 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 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


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


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.


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


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 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.
