Text-Mine Extreme

This web-based game is in the popular "move your mouse to avoid the evil alien" category - with a twist. You can play it on any of the many annoying websites that use "in-text placement ads" or as I like to call them "Text-Mines". You may already have played the game and not even been aware of it. When you scroll down the page and move your mouse carefully - avoiding the mouse-over pop-up ads in order to locate a bona fide hyperlink - you've been playing "Text-Mine Extreme". 

See PC Magazine's High-Tech Thanksgiving article for a great example - try to click all the normal hyperlinks without mousing over any of the hard-to-see green Text-Mines. I guarantee you'll play it over and over again - whether you like it or not.
