Pull back the sling, judge the arc, and hurl a projectile into a teetering tower of blocks until the whole thing comes crashing down on the enemies below.
Each level is a rickety fortress of stackable blocks with foes nestled inside. Drag back the slingshot to set angle and power, release to launch, and let physics topple the structure. Clear every enemy with the projectiles you're given to finish the level.
Fling Siege revisits Angry Birds, released by Rovio in 2009 and, famously, the company's fifty-second game rather than a first attempt. You haul a bird into a slingshot and let go, and everything after that is physics.
The design's real trick is that the structures are destructible in a way you can read at a glance. Wood, glass and stone behave differently, so a shot is not aimed at a target but at a load-bearing piece, and the satisfying outcome is a tower that comes down under its own weight rather than one you hit repeatedly. Three stars usually means finding the collapse, not the pig.
Fling Siege is an original free browser physics game in the slingshot-demolition tradition, built on wobbly, fully destructible structures. Just open and play.
