'''Jigsaws Galore''' is a shareware jigsaw puzzle program, originally developed by David P. Gray for Windows in 1996. As of 2025, it is still actively maintained and sold, with the latest release being version 7, available for both Windows and macOS. The program allows users to both solve existing puzzles and create new ones from their own images.

Jigsaw Galore is associated with the following file formats:

* '''Jigsaw puzzle files''', with the extension .jsm. Each file contains a single jigsaw puzzle, including image data, default piece number and shapes, and metadata such as the puzzle's title and author. The program comes bundled with several pre-made .jsm puzzles.
** Somewhere around version 7 the format was entirely changed. It is known that version 6.02 cannot read .jsm files from version 7.14, and vice versa. In particular, metadata is no longer kept in the .jsm file, but rather in an external .ini file in the program's jigsaw folder.
* '''Savegame files''', with the extension .jss, which preserve the progress of solving a particular puzzle.
** As of version 7.14, it is not possible to make savegames manually. Instead the game maintains autosaves for each puzzle.
* '''Piece shape files''', with the extension .asc. Plaintext files which define fancy piece shapes (pig, fish, square etc.). Each such file is a list of vertex coordinates.
