3 in Three

3 in Three is a classic puzzle game for the Macintosh, designed by Cliff Johnson; the protagonist is an instance of the number 3 in a computer. The game starts with the 3 being rounded off from a spreadsheet, just as the computer crashes. As a result, she is sent deep into the innards of the computer, where she has to solve a number of puzzles in order to get it working again, all the while dealing with a plethora of letters, most of whom have never heard of numbers and think that she's a damaged B.

Note: This game is available for public download at the official website. Everything players need to get it running is there, not only on the Macintosh, but on Windows as well.

Tropes featured include:

 * Automatic Level: The last elevator level will solve itself after only a single mouse click.
 * Chekhov's Gunman: The drone has the objective to delete the rogue 3. At the end of the game, the rogue is deleted.
