Obelisk Tycoon: Idle Miner is a free simulation game available on Android that invites players to manage their own mining empire. Players start by opening their first mining field and hiring miners to dig for ores and ingots. The game's idle mechanics allow miners to continue working and selling resources even when the player is not actively engaged, making it easy to progress and accumulate wealth.

In addition to mining, players can challenge managers to destroy obelisks, level up, and unlock new mining fields. The game features a variety of strategic elements, including a skill tree, upgrades for miners and ores, and the use of drones to enhance productivity. By collecting chests and crystals, hiring more managers, and making strategic investments, players can expand their mining operations and strive to become a successful tycoon.
