Looking for a stimulating, non-violent, puzzle solution game? This is it. I bought it for my early-teens son and ended up playing it more than my he did. I found it quite challenging and thoroughly fun.Other reviewers are correct that the game does not run on newer versions of Windows without taking a few additional steps. The solution (at least it's worked for me so far on Windows 7) is to install the program, then right click on the game icon it installs on your desktop and select Properties. Click on the compatibility tab in the Properties window and under "compatibility mode" select Windows 95 from the drop down window.
