9. Official Rules Scenario  Each creature has to survive in an hostile environment where food becomes progressively rare and competition gets higher and higher.  The creatures have an initial number of life points.  Each simulation time step costs a number of life points.  When this number reaches zero, the creature dies.

10. Official Rules Scenario  Hopefully, the environment is a maze containing a number of food distributors which are green when they contain food and red when they are empty.  A food distributor gets empty when a robot steps in front of it, transferring life points to the robot.  Then, it needs some time to get full again.  Hence, robots have to wander around in the maze looking for full food distributors, and possibly repairing the location of empty ones which are supposed to become full within a period of time.  The maze will contain a number of landmarks which can be helpful for the navigation of creatures.

11. Official Rules Scenario  At the beginning of the game, two robots are set at an arbitrary location in the maze.  All distributors are full of fresh food.  Then, the robots start looking for food distributors and consume their contents.  At the beginning of the game, food distributors need only a few seconds to get refilled, but as time goes, distributors need more and more time to get refilled, hence making the survival conditions for the robots becoming progressively harder.  After a few minutes of game playing the refilling conditions will make that there is not enough food to feed all robots and some robots will die from starvation.  The winner will be the last robot alive.
