Sky Kingdoms: Castle Siege

About Sky Kingdoms: Castle Siege: 3D Physics Puzzle Across 48 Levels

Sky Kingdoms: Castle Siege is a 3D physics puzzle adventure set above the clouds, where the goal is to launch magical familiars from a slingshot and bring down enemy fortresses. Spread across 48 levels and 12 sky regions, the game asks for careful aim, smart timing, and an eye for chain reactions as floating castles come crashing down.

Floating gray conical islands with grass tops and pink cherry blossom trees are scattered against a pale blue sky. Buildings with tiered blue roofs and beige walls sit atop the floating land masses. A large wooden slingshot structure stands in the center of a circular island platform in several scenes.

With 12 companions each carrying a distinct special ability — from dashing through supports to splitting into multiple projectiles, unleashing chain lightning, or diving into a courtyard — every shot opens up different possibilities. Falling towers trigger spectacular chain reactions, and replaying a level to find a smarter angle is part of the appeal. Coins collected from victories and chapter chests go toward unlocking distinctive costumes for the entire crew.

How to Play Sky Kingdoms: Castle Siege: Aim, Launch, and Topple Fortresses

The win condition is straightforward: defeat all guards. Fewer shots fired in a level earns more stars, and stars unlock new levels — they are never spent. Coins, earned separately, buy crew costumes.

Familiars and Their Abilities

Each of the 12 companions has one special ability available per shot:

• Dash through supports
• Split into multiple projectiles
• Unleash chain lightning
• Dive into a courtyard

Stars and Progression

Earning up to three stars per level unlocks new challenges. Replaying battles lets you discover smarter shots and complete a full three-star collection across all 48 levels.
