The Incredible Machine 3

The Incredible Machine 3, in some countries known as Professor Tim's Incredible Machines, is a new version of the Incredible Machine puzzle game series.

Being the same game as it's predecessor, the only new addition was the ability to resize the playfield in freeform mode. This version of the game was only released on Microsoft Windows and Macintosh, whereas The Incredible Machine 2 was only released on MS-DOS, so this game can be also thought of as a port.
