Microsoft’s Office Labs have created a new add-in for Office 2007 and Office 2010 that is a game called Ribbon Hero. Here’s the description from the site:
“Ribbon Hero is a game for Word, PowerPoint, and Excel 2007 and 2010, designed to help you boost your Office skills and knowledge. Play games (aka “challenges”), score points, and compete with your friends while improving your productivity with Office. “
I downloaded it a few days ago, and a) found it addictive, and b) learned some new things about PowerPoint that I did not know before!
You earn points for everyday things like copying and pasting, but you can also do “challenges” that will help you learn more features and help you be more productive with Office.
I highly recommend giving it a try!
