This paper describes an online game that is used to collect commonsense knowledge about human goals. The basic mechanics of the game is that people are presented questions that follow a finite number of pre-formatted templates that they have to fill. Provided answers are matched to verify whether they are similar and points (and relevance of the provided answer) are assigned based on the frequency of the provided answer (i.e., the consensus). The game was tested with 11 subjects.
