Back of box: Jack the duck is no ordinary quacker. He is witty and rather clever but this is not enough to get his precious egg to safety. He needs your help and ingenuity to get through the 20 mindboggling mazes. Beware of the hidden dangers, the foxes, the traps, but most of all, let those sleeping bulldogs lie. Start your adventure in level 1 and challenge your way through to level 20 or if you are feeling vigorous go straight into a higher level, but whatever you do, DON'T CRACK THE EGG!
