The Wisc-Online "GameBuilder" is a free, online tool for instructors. Currently, the site provides 16 different gaming frameworks into which instructors can incorporate their own course content. Games range from "Baseball" to "Spin to Win" and "Rapid Fire," among others. Students, if provided the appropriate link, can access the game for free, or can search the site for other games of interest. Instructors need to register with the site in order to build games that incorporate their own content, but, otherwise, there are no requirements or costs.
