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. FEATURES • Survive 50 increasingly challenging waves • Build winding mazes while placing your towers • Draft, keep, reroll, and combine gems • Follow templates to create advanced gem combinations • Discover gems with distinct stats and special effects • Defend against different enemy types and threats • Use the magnifier for precise, touch-friendly building • Enjoy crisp retro pixel art inspired by classic custom-map strategy games Every run is a new strategy puzzle. Will you chase a rare combination, reinforce the maze you already have, or gamble on one more draft? Build carefully. Combine wisely. Defend the path.

ReceptionRating · Positive reviews · Number of ratings

Keep on Mining! holds the better App Store score, 4.8 against 3.0. That said, the two scores are not equally well evidenced: Keep on Mining! has 33 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 79% of Keep on Mining!'s written reviews are positive against 100% of Gem Tower Defense Mobile's, so the app with the better star average is not the one people write more warmly about.
