Merge Dragons: Star Siege
Breed, Evolve & Fight Aliens
Free · Designed for iPad. Not verified for macOS.
NEW: Spider bosses & Wolf Soldiers! Merge dragons, blast fireballs, and defend the last realm from the alien swarm. How far into the siege can you go?
Hatch. Merge. Unleash legends. The Star Siege has begun.
The sky has cracked open. From the void between the stars, a swarm of alien invaders pours down to devour the last dragonflame in the world. You are the final Dragon Keeper — and one empty Hatchery is all that stands between them and the end.
Merge Dragons: Star Siege is a satisfying 3D merge game meets tower-defense battler. Combine adorable baby dragons into towering ancient beasts, build an unstoppable legion, and crush wave after wave of alien horrors.
SIMPLE TO PLAY, HARD TO PUT DOWN
Drag two matching dragons together to merge. Each merge changes their color and power — green to blue to purple to orange to red. Fill all five colors and your baby dragon evolves into a mighty grown dragon!
EPIC AUTO-BATTLES
Tap ATTACK and watch both armies charge into the middle in a chaotic 3D brawl — fire, fangs and fury. Your dragons vs the alien Void Swarm. Winner takes the realm.
ENDLESS STAR SIEGE
Every level you win, the rift widens and the aliens come back stronger and in greater numbers. How far into the siege can you push? Bigger enemies mean bigger rewards.
IDLE GROWTH
Your Hatchery earns gold even while you're away. Come back, buy more eggs, and keep merging toward the legendary Ancient Dragon.
COLLECT THE CODEX
Every dragon you evolve is recorded in a beautiful 3D Codex. Can you unlock them all — from the tiny Dragon Eggling to the world-shaking Ancient Dragon?
