Tagr is a game released by Microsoft Office and Blockdot, designed to allow players to earn point by tagging images. The actual gaming experience is rather simple. Users are presented with a certain image for which the game has already reserved a few tags which can no longer be used. Participants in the Tagr game need to come up with their own tags better describing the image and earn points for each tag. And if you already guessed that this game is designed to help Microsoft, you are right on the money.
The Redmond company has partnered with Blockdot for the creation of the game, which is actually set up to allow users to tag Office clip art and images. Ultimately, the game will end up benefiting end users which will get to find Office content based on the tags entered as a part of Tagr.
