Gem Keep app icon: a glossy gem above a castle

Gem Keep

Tower Defense. Forge gems. Merge them. Defend the keep.

A tower defense you can pick up in a minute

Forge gems, drag them onto your towers, and merge two gems of the same grade into a stronger one. Choose your colours wisely: every gem fights in its own way.

Hold off the cheeky Invaders across hundreds of bright, hand-tuned levels in the Meadowlands.

Coming soon to Android

Gem Keep is made by a family who love tower defense. Want to know the day it launches?
