About this game
Merge Elementals: Castle Defense alternates between arranging a magical army and holding off a horde. Matching fighters combine into stronger tiers, with twelve elements offering different attacks, slows and area effects. Each world contains ten waves ending in a boss, and your army and gold continue into the next biome. A limited grid makes every purchase and merge matter. Between encounters, upgrade your magic and choose three spells to take into battle.
How to play
Drag two elementals of the same type and tier together to merge them. Gold buys first-tier fighters; higher tiers come from combining them. Rearrange the lineup before pressing Start Wave, because merging is locked during combat. The fighters attack automatically, leaving you to time your spells and protect the wall. Defeated enemies drop gold for the next preparation phase. Use the break between waves to review the space available, improve the army and prepare for the world's boss.
