Merge Elementals: Castle Defense

???? 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. Free to play, no download, no sign-up.
