(There's no video for The Master Guesser yet. Please contribute to MR and add a video now!)
The Master Guesser is a very crude/simple text based game in which you tell it how many possible numbers to choose from and how many maximum tries it will let you guess the random number it will generate. That's it. This game's code is less than 1KB and since it was made with BASIC, the BASIC runtime code is actually 40 times bigger than the program itself :P
