Rats need to eat healthily just like humans do and it's down to Doctor Rat to help the rat groups establish a safe diet and negate their dietary restrictions. However, Doctor Rat cannot discuss these restrictions with the groups directly and can only tell them if a meal is bad for them. 
 
With one player taking on the role of Doctor Rat and the remaining players taking on the roles of the various rat groups, you'll all win or lose together as you uncover your groups dietary restrictions and hopefully make it to the end of the 8th round!
 
Will you be graduating victorious safe in the knowledge of what you can and can't eat or will you all fail to pass the test?
