I actually featured Advertputt on the blog in the past. Advertputt is a putt putt golf game that you play in your browser. It is actually like a demo page, by damp gnat, that they will setup for you (if you are a business), in the form of advergaming, as a marketing strategy.
Anyhow, the objective of Advertputt is to get all 12 holes in as few as putts as you can. Use the mouse to aim and adjust the power for each putt. All of the holes are sponsored.
