Crush the Castle is a top flash game that holds fond memories for many of us, as we spent countless hours playing it on school and library computers. This more realistic version of Angry Birds is simple yet addictive, with the goal of the game being to fire large boulders at flimsy castles filled with characters to crush them. In each level, the player must eliminate all the characters to advance.

Despite being a relatively simple flash game, Crush the Castle has surprisingly nice graphics, adding to its charm. The game’s physics engine also adds to the realism of the gameplay, as players must consider various variables such as projectile speed, angle of fire, and gravity when launching boulders at the castles.

This gives the game a ton of replayability and helps cement it as one of the best flash games ever.
