Angry Birds Classic is a casual physics puzzle game in which players use a slingshot to send birds into the green pigs' fortified structures and recover stolen eggs. The game combines aiming, timing, destructible building elements, and progressively challenging level layouts. Its cartoon presentation is accompanied by dynamic music, while the core rules are designed to be easy to learn.

Slingshot aiming and physics

To launch a bird, drag the slingshot to set its direction and power, then release. Successful shots depend on judging the trajectory and targeting weak points in structures. Glass panels, stacked supports, and TNT placed near important sections can affect how a building breaks, so examining the layout before firing is part of solving each puzzle.

After a shot, the next launch can be planned around what has already collapsed and the characteristics of the remaining bird. This makes timing and shot order relevant, especially when a chain reaction can bring down several towers.

Bird abilities and tactical choices

The birds do not all behave the same way. Some can accelerate during flight, some split into multiple projectiles, and others activate a special effect when tapped in the air. The source also describes explosive black birds and green birds that can return like boomerangs. Choosing when to trigger an ability can help target fragile areas or reach parts of a structure that a normal flight path would miss.

Levels, scores, and replaying

Classic Mode is described as containing 15 original chapters and hundreds of levels, with difficulty increasing as players progress. Levels use a three-star scoring system, encouraging repeat attempts with better angles, fewer birds, and more efficient destruction. Different launch approaches can produce different results, so replaying a completed puzzle is part of the scoring system.

Power-ups and additional content

Optional power-ups are available for difficult puzzles. They can reposition buildings, increase attack strength, or help fine-tune shots, while the supplied description presents them as additions to skill-based play rather than replacements for aiming. The source also mentions bonus levels, hidden Easter eggs, and environments such as seaside and winter settings. An Eagle Power-up is described as available through in-app purchase.
