The Digging Game is a mini-game that appears in A Link to the Past.
"Explorers in the Dark World noted that it was full of treasure and hidden items. An ambitious landowner in the southeast section of the Village of Outcasts took advantage of that fact by fencing off his land and charging treasure hunters 80 Rupees to dig up the dirt for 30 seconds. If they found anything, they could keep it! A Piece of Heart, the real prize, was hidden well and moved often."
"A Big Dig"
"There were many places to dig in the sizeable Treasure Field. While it was quite possible for adventurers to find enough Rupees to earn their money back, it usually took severally attempts to find the buried Piece of Heart that was hidden somewhere in that large yard."
