According to the manual, "There are elements of the gameplay that are totally unique to the CD32 version and are not referred to in the Amiga manual. These include three all new mission levels, where Brian has to hunt for treasure, free caged animals and free a jammed bucket from the bottom of a well! Also there are completely new special challenge levels. Occasionally a top hat can be seen floating above one of the levels on the map screen. If Brian enters that level he will be offered one of two special challenges. 1) "Cup 'N Ball" - A ball is placed under one of three cups and you have to guess where it is after they have all been shuffled around. 2) "Cardorama" - A card game where you have to match up the bonus cards."
