Oviraptor Hazard is a memory-based puzzle game. Utilizing the same core gameplay mechanics as Treasure Hunt, this version features a prehistoric setting where players control a Dinosaur on a quest to rescue its lost egg. At the beginning of each stage, the map is briefly uncovered to show the safe paths and the locations of dangerous obstacles or predators; once the layout is hidden, the player must rely on their memory to navigate the treacherous terrain safely and guide the dinosaur back to its egg without hitting any unseen hazards.
