Upgrades help you progress faster in the game by enhancing various aspects of your gameplay. They can be purchased using Crowns. Crowns are earned by mining, but obtaining them isn’t guaranteed — chests are randomly found while mining. Occasionally, a Golden Chest may appear, containing more Crowns than a regular chest. Players can increase the amount of Crowns obtained by upgrading Crowns Boosts, which raises both the quantity of Crowns per chest and the chance to receive them overall. This helps you earn more and progress faster.
