Ocarina of Time Speedrunner Discovers How to Manipulate Dampe's Notorious Gravedigging Lottery

Speedrunner Poodleskirt and ZFG demonstrate an RNG manipulation technique for Dampe's Gravedigging Tour minigame in The Legend of Zelda: Ocarina of Time 3DS.

Nearly three decades after The Legend of Zelda: Ocarina of Time first appeared, its players are still discovering that apparently random events can conceal surprisingly complicated mathematics. A new investigation by former speedrunner and technical enthusiast Poodleskirt has revealed a method for predicting the results of Dampe's Heart-Pounding Gravedigging Tour, one of the adventure's more frustrating minigames. During the activity, young Link pays the gravedigger to excavate patches of soil in the hope of receiving valuable rewards, including a Piece of Heart. The prizes appear random, leaving generations of players repeatedly spending Rupees while hoping for a favourable result. Poodleskirt's investigation identified a relationship between the game's random-number state and Dampe's blinking animation. By observing the character's eyes and using a specially developed calculation tool, players can estimate the correct moment to request another dig. Additional actions can influence the random-number sequence, potentially reducing the time required to achieve the desired outcome. The discovery was demonstrated by prominent Zelda speedrunner ZFG, attracting considerable interest from enthusiasts who study the game's internal systems. An important qualification is that the demonstrated technique concerns the Nintendo 3DS version of Ocarina of Time. Its applicability to the original Nintendo 64 release or other versions has not been established. The finding is nevertheless a fascinating example of the technical archaeology performed by speedrunning communities. Players frequently discover connections between animation timing, internal counters and seemingly unrelated game mechanics. Nintendo probably intended Dampe's activity to be a simple test of luck. Almost thirty years later, somebody has turned watching an elderly gravedigger blink into a legitimate mathematical discipline.
