Puzzle

Puzzle is a desk accessory written by Andy Hertzfeld for the original release of the Macintosh in January 1984. It was included with System 1 through 7.1.2.

History
During a preliminary review in September 1983, software manager Jerome Coonen considered dropping Puzzle from the original release of the Macintosh 128K due to the desk accessory's 6 KB size, considered relatively large at the time. Hertzfeld then recoded it in assembly language instead of Pascal, reducing its size to less than 1 KB, allowing it to stay as part of the original Macintosh system software release.

Updates
The desk accessory was updated very little until System 7, when it delivered a deadpan recording of "Ta-da!" instead of a simple beep when the puzzle was solved.

Replacement
Puzzle was replaced by the more graphical Jigsaw Puzzle in System 7.5, which was released on September 12, 1994. However, the older Puzzle is still functional through Mac OS 9.2.2 and can be run in the Classic environment of Mac OS X through version 10.4.11. It was later released as a Dashboard widget on Mac OS X 10.4 Tiger and removed finally in macOS 10.15 Catalina
