The plot of the game is that a whole ton of hamsters have escaped their cages (as hamsters are so prone to do) and they are now trying to survive in a multitude of environments, and you must help 'em out. To do this you must click on the icons at the bottom of the screen, and then click on a specific hamster, this will assign that hamster that task. After having the hamsters do a lot of tasks you can eventually get them to the exit(s). Each level has a required number of hamsters that you have to save in order to go to the next level. Be aware of devious traps that often take many a hamster life. There is a time limit, so move quickly.
