About the game

A horde is marching on your castle, and a wall plus a few elementals are all you have. You stack identical fighters together to build stronger ones, then watch them fire at the enemy while you time your spells.

Each world runs ten waves and ends with a boss. Between waves you rearrange the grid, buy a new fighter, level up magic and pick three spells to bring along. Grid space is tight, so every merge is a small choice about what to keep.

How to play

• Drag one elemental onto another of the same type and tier to fuse them into the next tier up.
• Gold buys only tier-one fighters. Everything stronger has to come from merging.
• Press Start Wave when your line-up is set. Merging is locked during combat, so cast spells at the right moment and protect the wall.
• If the wall falls, spend gems to revive on the spot and keep fighting.
