Tile Game

Tile Game is a puzzle game widget included with the Dashboard feature that was released with Mac OS X 10.4 "Tiger" on April 29, 2005.

Features
The Tile Game resembles Andy Hertzfeld's original Puzzle desk accessory that had been included with classic Macintosh system software ever since System 1 in January 1984. The default cat image in the Tile Game can be replaced by finding a desired image file in the Finder and then while dragging it without releasing the mouse button, pressing  to bring up the Dashboard, then dragging the image file over the Tile Game and releasing it.

Discontinuation
The Dashboard was gradually phased out of macOS as 10.14 "Mojave" had it turned off by default. It could be turned back on in the Mission Control pane in System Preferences. However, it was removed completely with the release of macOS 10.15 "Catalina" on October 7, 2019.
