Since after the first round of the game, its rules will be obvious to everyone, the second round will take a different format. The teacher divides the children into groups of 4-5 and distributes different roles (for example, an architect, a dog owner, a taxi driver, a transport manager etc.) using cards or slips of paper to every kid within the group. The cards should be kept secretive. No one should know who is who. One of them will receive the role of a saboteur. Each role will also have a different mission to achieve in outlining a perfect city. These could be the missions stated in Round 1. The participants (citizens), other than the saboteur, win if they manage to complete their missions during the game, and the saboteur wins if he/she manages to manipulate their peers without their knowledge to achieve his goal.
