'Goldy' is born with all five-gem attributes of the 'GoldeFy' world, and one of the attributes is strongness. The strong attributes given to the newly born 'Goldy' are given randomly. They can naturally control the population with factors such as breeding and enhancement.
Despite the fact that GoldeFy is a mining-based idle game, all characters need to sleep and eat. Based on reality, each Goldy's stamina lasts for a limited time so Goldy should also get enough sleep, rest, and food. Goldys may have an advantage on auto-mining rewards through character enhancements. Therefore, the rewards in the auto-mining system are based on Goldy's stats.
