Gemstone Guardians

Gemstone Guardians is a tower defense game in which you choose and combine towers to stop enemies from reaching the end portal. Each round, you choose one of five randomly available towers; the others turn to stone. Place your towers to redirect enemies away from their destination.

Build and combine

Towers of the same type can be combined to increase their power. Certain combinations also create special towers with effects that can help you through later rounds. Each kill permanently increases a tower’s damage, and when you combine towers, their kill counts are added together. Getting the right towers kills early can help you build powerful combinations later.

Face enemy waves

Each round brings a wave of increasingly difficult enemies, including flying and sprinting enemies and bosses. Enemies have different armor types, making them more resistant or vulnerable to certain tower damage types. A damage meter shows how effective your towers and placements are.

Spend gold

Kills grant gold, which you can spend to increase the chance of getting higher-quality towers in following rounds or to improve the chance of receiving a particular tower type. This can help you work toward specific special towers.
