About Orb Siege
Orb Siege is a bright casual physics arcade game where the goal is simple and satisfying: pull back a slingshot, fling colorful affinity orbs, and bring down wooden, stone, and glass fortresses across 100 hand-crafted levels. A wooden slingshot sits atop a square crate on the left side of a green field, and small round green creatures with simple black eyes and smiles are positioned on or near brown platforms — those are your targets. Built for quick runs on both desktop and mobile, Orb Siege blends arcade destruction with puzzle-style thinking as each fortress demands a different approach.
How to Play Orb Siege: Knock Down Fortresses and Clear Every Green Blob
The objective on every level is to knock down blocks and clear all green blob targets. A dotted white arc line extends from the slingshot across the blue sky in one scene, giving a visual read on your trajectory before you let go.
Orb Affinities
- Ember: hits wood hard
- Frost: cracks glass
- Quake: shakes stone
- Charm: balanced against all materials
- Boom Orb: call these in when you need a blast
Matching the right orb to the right material is central to clearing each fortress efficiently. Run out of orbs after clearing the fortress and the next level unlocks. Rankings are accessible from the main menu, the pause menu, or the level-clear screen, so chasing a top spot on the leaderboard is always one tap away.
Controls
- Drag orb left (mouse or touch): stretch the slingshot and aim
- Release: launch the orb
Landscape orientation is required for play.
