The program is easy to install. Have previously switched from Windows XP to Windows 7 my operating system. It turned out that the full screen mode can not be activated! Running imprint on the system requirements, but this should be possible! A request from the Support Line showed that the full-screen mode is not possible! Too bad, because the individual stones are now but quite small, which is the game not conducive. Since many change their operating system, should it think twice before he At length, this version! Therefore, only two stars!
