9 Best Flash Games of All Time
Crush the Castle

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 that add to its overall charm. The physics engine of the game also adds to the realism of the gameplay, as players must take into account various variables such as projectile speed, angle of fire, and gravity when launching boulders at the castles.

As the player progresses through the levels, new obstacles such as walls, towers, and moving targets make it more challenging and require precise aim and timing to overcome. The game also includes a level editor, allowing players to create and share their own custom levels with others. This gives the game a ton of replayability and helps cement it as one of the best flash games ever.
