4 Fantastic Fish Amazon Adventure takes the cash-fish format to a river setting and adds distinct features. Piranha Frenzy brings fresh cash prizes onto the reels, Lost City offers a Pick-a-Win route, and the Amazon respin feature uses a 'Gator to combine and double a filled reel's prizes. A Giant Anaconda swaps fish positions. These are more than renamed ocean characters: the extra pick feature and piranha events should be covered when comparing the Amazon edition with the original fishing slot.
