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 โ€” 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 โ€” 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 โ€” 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.
