This software allows normal-form game experiments to be conducted over the Internet. Within an experiment, subjects participate in one or more matches. Each match is a series of one or more stage games. Several methods of rematching subjects between matches are offered.

Two general types of games are supported:

• Traditional games - payoff tables specify stage game earnings; subjects' earnings are simply the payoffs accumulated over time.
  
  
• Match-play games - payoff tables specify a probability of winning a point; a match is won by the first player to accumulate the needed points. This match winner earns a fixed payout, while the opponent earns nothing for the match.

For additional information on how to use this software and all of its features, refer to the material below.

Requirements - Use of this software requires installation of WebStart, which is now a component of Sun's Java Runtime Environment. Please refer to the WebStart help for more information.

Before you run an experiment with this software, please read this section to better familiarize yourself with how the software functions.
