Angry Birds is a physics-based puzzle game where you pull back a slingshot, aim a bird, and launch it at structures sheltering green pigs — with the goal of popping every pig on the field using as few birds as possible.

Each bird type has a unique mid-air ability, and each structure is built from glass, wood, or stone that responds differently to impact. Play this free online game in your browser on PLRun with no download needed. Angry Birds launched the most recognizable franchise in mobile gaming history.

Originally released in December 2009 by Finnish studio Rovio Entertainment, the game puts you in control of a flock of wingless birds whose eggs have been stolen by mischievous green pigs. Your weapon is a slingshot. Your ammunition is the birds themselves.

The objective on every level is the same: destroy the pig-sheltering structures by launching birds into them, using physics — gravity, momentum, and material fragility — to cause maximum collapse. What makes players return after more than a decade is the gap between simple controls and deep strategy.

Pulling back the slingshot takes one second to learn, but earning three stars on a tough level requires reading the structure's weak points, choosing the right bird for the right material, and triggering chain reactions through TNT crates and load-bearing supports.
