Economics professor, Ariel Rubinstein, created this website to provide teachers some basic instruction in Game Theory along with "free user-friendly didactic tools for conducting web-based thought experiments." The materials are based on his experience in teaching a course in Game Theory using web-based experiments during the years 1988 to 1999. Sample problems are available in five languages: English, Portuguese, Spanish, Russian and Slovak. Some articles are available from the home page, but access to the instructional material requires instructors and students to register at no cost. A slide show reviews the registration process and demonstrates the web-based course.
