The Great Machine

"The Evil Mad Scientist Doctor Herr Guffin has left his assistants (Igor, Igor, Igor and lest we forget, Igor) in charge of his experiments while he goes to a convention on 'Evil Inventions and the Applications in Modern Society'." "The experiment in particular is a machine he designed to breed a better rat (because the kids these days had gone and invented a better mousetrap). It is a mixture of mechanical and electronic feeder/torturing device." "The object of the player (called Igor) is to have his favourite rat the biggest by the time the master returns." "This involves making sure that toggles tilt the pipes in the machine such that the food pellets go to the player's rat - and avoiding/rotating the shocking motor such that the other rats are shocked (which causes them to lose food pellets, probably through vomiting)." "There are event cards as well (things like Cardiac Arrest - fattest rat gets a chronic heart attack and dies)."
