Play Merge Elementals: Castle Defense online in this strategy game from the approved Playgama catalog. The horde is marching on your castle. All that stands in its way is a wall and a handful of elementals. 🔥💧🌍 Merge identical fighters to push them up the tiers. Fire, water and earth cross into wind, lava and nature, which cross again into ice, energy, spirit and sandstorm. Twelve elements: some burn an area, some slow the horde, some delete a single target. ✨ Between waves, level up magic and take three spells into battle: fireball, frost storm, chain lightning, meteor shower, dragon call. 🌋 The campaign never ends: swamp, snow peaks, desert tombs, fungus forest, lava inferno, void and meadows. How to play: Drag identical elementals onto each other: two fighters of the same type and tier fuse into the next tier.

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.
