About Sky Kingdoms: Castle Siege

Launch magical familiars, topple sky castles and master every shot.

Take aim above the clouds in Sky Kingdoms: Castle Siege, a 3D physics puzzle adventure featuring 48 levels across 12 sky regions. Launch magical familiars from your slingshot and bring down enemy fortresses.

Each of your 12 companions has a special ability: dash through supports, split into multiple projectiles, unleash chain lightning or dive into a courtyard. Time your moves and turn falling towers into spectacular chain reactions.

Earn up to three stars per level to unlock new challenges. Collect coins from victories and chapter chests to unlock distinctive costumes for your entire crew.

Replay battles, discover smarter shots and complete your three-star collection. Explore floating islands, face increasingly challenging defenses and choose your view: stay behind the slingshot or follow every projectile through the sky.
