This game is very addicting. It was installed a couple of weeks back as on the Vista Ultimate add-ins via Microsoft Update. Garth had pointed it out on his blog last month, how to kill a couple of hours, no kidding. Garth’s Post on Microsoft Tinker
It is a load of fun and reminds me of the incredible machine back in the days of Dos. There was also a Microsoft Puzzle game set back in the Windows 95 days that I had installed for my father. My father wasn’t great with computers back then, but he liked sitting down and playing the puzzle games. Now he can get around a computer pretty good although he doesn’t use it much.
If you have Vista Ultimate, I would suggest downloading this game as part of your updates and checking it out. It’s time consuming and way to help you practice problem solving skills.
