Play Sling Siege online
Sling Siege is a physics siege puzzler: drag the slingshot, arc a stone into a hand-built fort, and pop every last Greebling hiding inside.
Nine forts escalate from a simple wooden wall to stone keeps and twin peaks — wood cracks, glass shatters, stone shrugs off glancing blows, so every fort wants a different weak point. Knock out a support and gravity does the rest.
Five stones per fort, three catapult repairs for the whole siege. Spend stones wisely: one-stone clears earn three stars. Your best score is saved locally.
How to control Sling Siege
- Aim: drag the stone back on the slingshot (mouse or touch)
- Fire: release to launch
- M: mute audio
- Enter: start / play again
How to play
- 1
Drag the stone back on the slingshot and release to fire at the fort.

Pop every green Greebling: direct hits, falling blocks, and collapsing towers all count.
- 3
Wood cracks, glass shatters in one hit, stone barely budges — aim for weak supports.
- 4
You get 5 stones per fort and 3 catapult repairs for the whole siege; run out of stones and a repair is spent to retry.
- 5
Clear all 9 forts to complete the siege. Best score is saved locally.
Tips for a better run
Aim for the base, not the Greebling: one cracked support drops the whole tower onto everything below it.
Glass shatters in a single solid hit — prioritize glass walls shielding Greeblings.
Stone soaks up punishment; go around it or drop something heavy on it instead of chipping away.
Watch the dotted arc while aiming: flat fast shots smash walls, high lobs drop stones onto roofs.
A stone that misses everything is a wasted stone — the 1-stone clear is worth three stars.
Frequently asked questions
Is Sling Siege related to Angry Birds?
No. Only the slingshot-siege genre is shared — a classic physics-puzzle format. Sling Siege is an original implementation: all 9 fort layouts were hand-designed for this game, the Greeblings are original characters, and the name, artwork, and code are original. It contains no third-party IP.
How do I aim and what breaks what?
Drag the stone back on the slingshot to aim (a dotted preview shows the arc), release to fire. Wood cracks after a couple of solid hits, glass shatters in one, stone barely budges — knock supports out to bring the whole fort down.
How do I win?
Clear all 9 forts. You get 5 stones per fort and 3 catapult repairs for the whole siege — run out of stones on a fort and you spend one repair to retry it. Lose all 3 repairs and the siege ends. Your score and best are saved locally.
Can I play on my phone?
Yes. Drag with a finger or mouse; the slingshot, HUD, and canvas scale to small screens.
