Gem Tower Defense Mobile

Draft towers and build mazes to control enemy paths. Every run is different. Outsmart waves with strategy, not luck. If you know, you know.

Build the maze. Draft your gems. Survive all 50 waves.

Gem Tower Defense Mobile is a retro reimagining of the classic GemTD custom-map experience, rebuilt from the ground up for touchscreens.

Every gem you place is both a tower and part of your maze. Shape enemy routes, create powerful choke points, and keep each wave under fire for as long as possible. One clever placement can transform your entire defense.

Each draft brings a new decision. Keep the gem, reroll it, or combine matching gems into stronger towers. Follow gem templates to work toward powerful combinations, or adapt your strategy when the pieces you need refuse to appear. No two defenses play exactly alike.

Study each gem’s damage, range, attack speed, targeting, and special effects. Mix colors and abilities to cover weak points, slow dangerous enemies, and prepare for the next wave. When every tile counts, use the magnifier for precise placement.
