Play Online GemCraft Labyrinth: Lost Chapter
If you’ve ever wondered what happens when you mix a classic tower-defense setup with customizable magic gems, GemCraft Labyrinth: Lost Chapter is here to answer the call. You start each level by placing gems that shoot at waves of nasty creeps, but the real fun is in combining those gems to tweak their attack speed, range and special effects. Want a gem that slows enemies down in a huge radius? You can do that. Prefer an explosive gem that deals massive damage to armored foes? That’s on the table, too.
What really sets the Labyrinth edition apart is its maze-building twist. Instead of enemies following a fixed path, you carve your own winding corridors to funnel them into kill zones. You get to line corridors with traps, turbo-boost your gems’ fire rate, or anchor giant mana pools that supercharge nearby towers. As you play, you unlock skill trees and artifacts that grant new abilities—like summoning a devastating storm or raising temporary walls to reroute attackers in a pinch.
Even if you aren’t the type to obsessively chase high scores, this game manages to keep you hooked with escalating challenges and secret bonus stages that ask you to rethink everything you thought you knew about tower defense. The story threads through the action without ever feeling like a homework assignment, so you can just focus on devising new ways to outsmart your foes. Before you know it, hours have slipped by and you’re already plotting your next labyrinth.
