Wine (or WINE) is a program originally written for Linux systems to provide an execution layer of the more common Windows APIs in order to run Windows programs without modification. It can be used to play Tomb Raider and Lara Croft Games intended for Windows on Linux, BSD, and MacOS X, but results may vary widely.
Although Wine is open source, there are also commercial versions that support more applications/games. These also provide a graphical user interface for setup etc.
