Imagine that you stand in front of a burning house where several people are trapped and begging for your help. Can you save them all before the whole building collapses? Maybe you can! But you need to have good logical thinking. Some victims have to be rescued first because the flame is dangerously close to them. Maneuver between the obstacles, close and open the doors, find the shortest way across the house. Perhaps you can even figure out how to save a few people at once rather than getting them out one by one!
