About the game
Merge Elementals: Castle Defense combines merging with tower defence. A horde marches on your castle, and you drag identical elementals together to fuse them into higher tiers. There are twelve elements, and some burn an area, slow the horde or remove a single target.
Between waves you upgrade magic and choose three spells. Each world has ten waves, ending in a boss. Your army and gold carry over between worlds.
How to play
- 1🖐 Drag identical elementals onto each other: two fighters of the same type and tier fuse into the next tier.
- 2Gold only buys tier one — everything above comes from merging, and grid space is tight, so think about what you combine.
- 3▶️ Once your line-up is ready, hit Start Wave.
- 4Merging 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.
- 5💰 Every kill drops gold.
- 6🔁 Wave over — back to the prep phase: buy, rearrange, upgrade.
Tips
- Plan your merges carefully, because grid space is tight and only tier one costs gold.
- Cast your spells on time during combat, since merging locks once the wave starts.
- Use the prep phase to buy, rearrange and upgrade before pressing Start Wave.
From the developer
🏰 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. Ten waves per world, the last a boss 👹. Your army and gold carry over between worlds, so progress is never lost. 🎁 Chests, keys, scrolls, castle upgrades, daily rewards. ☁️ Cloud saves: start on your phone, continue on desktop. 🎮 Merge, tower defense and strategy in one.
