About game
Combine basic units to conjure powerful spirits and hold your ground against incoming monster swarms. You drag identical units onto each other to unlock advanced forms that blast, freeze, or incinerate everything that approaches your walls. Merge Elementals: Castle Defense keeps you busy planning your grid layout while managing limited gold for new recruits. Strategy becomes vital because once a battle begins, your units fight automatically while you focus entirely on timing your destructive spells. You navigate through diverse landscapes like frozen peaks or scorching lava pits to test your tactical limits against massive bosses. Your army progression carries over between zones so every victory strengthens your long-term setup. Regular upgrades to your castle and magical arsenal ensure you always have the firepower needed for tougher waves. Merge Elementals: Castle Defense lets you enjoy high-stakes tower defense right in your browser without any annoying downloads or sign-ups.
How to play
🖐 Drag identical elementals onto each other: two fighters of the same type and tier fuse into the next tier. Gold only buys tier one — everything above comes from merging, and grid space is tight, so think about what you combine.
▶️ Once your line-up is ready, hit Start Wave. Merging locks during combat: your fighters aim and shoot on their own, while your job is to cast spells on time and keep the wall standing. 💰 Every kill drops gold.
🔁 Wave over — back to the prep phase: buy, rearrange, upgrade. The last wave of each world is a boss, and beyond it lies the next biome.
💎 If the wall does go down, you can revive on the spot for gems and carry on.
