The legendary Gem TD from Warcraft III and Dota, rebuilt from scratch — natively for iPhone & iPad. No ports, no ads-with-a-game-attached. The real thing.
A faithful remake of the WC3 / Dota classicFree beta · iPhone & iPad · iOS 17+
Each round, place 5 random gems — then keep only one. The rest turn to stone and become the walls of your labyrinth. Bad luck isn't wasted; it's bricks. Carve the longest, cruelest road you can, then hold it for 50 waves.
Flyers that ignore your walls, invisible stalkers, evasive tricksters, self-healing tanks — and bosses.
Combine exact gem sets into elite towers — auras, chain lightning, poison, slows — true to the original recipes.
Every wave is a hand-built creature with its own abilities, animations, and counters.
Diamond hits like a truck but can't touch flyers. Opal sees the unseeable. Every choice matters.
Swift + SceneKit, built for Apple hardware. No web wrapper, no Unity bloat — launches instantly, runs cool.
Single-player, offline-friendly, no energy timers. Just the game.

Gem TD is one of the most beloved custom maps ever made — born in Warcraft III, kept alive for nearly two decades in the Dota 2 Arcade. But it never had a real home on mobile.
This is that home: the place-five-keep-one heartbeat, the authentic crafting recipes, the Dota-style aura stacking and deferred damage — rebuilt piece by piece and tuned by hand, not ported. If you've ever kept a terrible gem just because the wall was in the perfect spot, this was made for you.
One email when the game hits the App Store. Nothing else, ever.
