Gem Miner TD

Gem Miner TD combines mining, maze-building, gem merging and autobattler elements with tower defense. You play as a miner who digs paths for enemies, combines gems to create stronger defenses and tries to survive waves of mobs. Each run can lead to a different build through gem combinations and Augments.

Dig and defend

Rather than building around a fixed path, you dig the route through each map. Gems serve as your towers, and merging them makes them more powerful. The game includes over 60 unique gems and over 80 Augments, which can stack buffs, enhance gems, empower your miner or change gameplay mechanics.

Maps and miners

There are four maps and nine Miners, described as classes, alongside over 50 mob types. The combinations of gems and Augments offer different ways to build your defenses from run to run.

Game modes

You can climb the leaderboards, unlock the Vault to further customize your build, and test your defenses in Endless Mode. The game uses colorful pixel graphics, and a run can end with you being dragged into lava, freezing water or poison pits.
