Element Castle

Match gems. Merge mages. Defend the castle.

Created specifically for Mobile Game Jam 2026.
Jam theme: Synergy - "2 + 2 = 5", interpreted through a tower defense where two simple mages can merge into a stronger hybrid spell caster.


Note: The game is currently in development, so future releases may differ from the jam version. The jam version will be available for download and will be named 0.1.0-GameYamVersion.




Element Castle is a compact, mobile-first match-3 tower defense game. Every tower starts as a puzzle move: match elemental gems, create mages, place them along the path, then decide when to stack, merge, or spend their limited charges.

A crooked magical castle is under siege. Enemies push through winding lanes, and your defense is built from seven elements: Fire, Water, Earth, Lightning, Poison, Dark, and Ice. Each element has a clear combat role, from burning damage and slowing pools to stuns, curses, poison, and freeze control.

Merge two single-element mages to unlock hybrid spell kits. Lava burns and slows. Storm puddles shock enemies inside a zone. Plague stacks poison and dark damage. Frozen pools lock down lanes. With 21 hybrid recipes, each run is about turning your puzzle board into the right defense before the next wave reaches the castle.




How To Play

  1. Choose an unlocked node on the world map.
  2. Match 3+ gems to create elemental mages.
  3. Drag mages from the backpack into tower slots.
  4. Stack matching mages to level up and refill charges.
  5. Merge two different single elements to create a hybrid.
  6. Survive all three waves before enemies break the castle.

Jam Note
