Students could play Ecity games in different ways. These are some proposed scenarios.

· Individually. From home or directly from the classroom, the student has to face lonely to problem resolution. He/She needs to make the whole process with only the help of the teacher, which will be available to guide and orient. The student must identify what is really the problem, break it down into smaller problems and try to go looking for solutions gradually. The student should also seek information and learn to relate this new information with what he/she already know.

· In pairs. Two students play the game assuming different roles. One of the two students analyses the scenario and the issues involved while the other is in charge of the actions. Both students collaborate and discuss in different roles in order to achieve the best solution to the problem.

· In groups. The choice of group work usually begins in the classroom, where the teacher divides the class into teams to work with eCity. Teams should be between 5 and 7 members to have a meaningful use. Within each group, students identify the problem, divide the work, propose possible scenarios and solutions in its earliest stages and seeking information. Then they meet up again to gather all the information, debate and reach consensus. If they fail to reach the solution, they would repeat the process. Additionally, during the process of finding the solution or at the end of the problem, they can share what they learned and how they have done with other classmates, thus increasing the interaction.

Within the groups each student will have a role to determine its involvement in solving the problem. Usually the students themselves are who assign roles in such a way that everyone does the job best known and where he/she feels more comfortable. At other times it is the professor who does, seeking that all students perform all roles, not only the easier and better roles that they know.
