Idle Tower Builder: Miner City is a simulation game that puts you in charge of building the world's tallest tower. The game has been played by over ten million people on web browsers and is now available on Android. In this game, you gather or produce resources to build your tower, starting as an idle miner tycoon. You can upgrade your quarry, hire stone miners, produce bricks, and make upgrades. As you progress, you can chop wood, expand the lumbermill, and build a crane to deliver bricks to the higher floors of your tower.

The game has an auto-clicker, which means there is no need for extensive clicking. You can play the game offline, and there are no intrusive ads. Ads are shown only if you want them in exchange for a bonus. The game is designed to show you how upgrades affect production and tower construction. You can see new workers, miners, and builders appear as you improve your facilities and become a building and mining tycoon.
