I have found Solitaire being the #1 time filler game. I just notice this recenly how frquent people played Solitaire in their machines. I think you seen people played it in any location whenever they get their hands on a computre or laptop, solitaire is always being played. So do you guys played it to pass the time, as a challenge, or just for the heck of it?
An interesting note: I learned the reason Micosoft had solitaire mandatory in their windows was to design to help people to drag and click, so it is a form of teching tool for people to learn how to use windows. :)
