The Flash version was released on April 28, 2009, and versions for the iPhone and iPod Touch were released on January 19, 2010. Notable for its "flinging" game mechanic, which influenced the popular mobile game Angry Birds,[2] the goal of Crush the Castle is to kill all inhabitants of various castles by using a trebuchet to fling large rocks or bombs.

The developers cite the game Castle Clout, released October 4, 2008 by Liam Bowmers, as their inspiration.

[1][4] Armor Games requested and received permission from Bowmers to use his ideas for the development of Crush the Castle.

[1] IGN's Jeffrey Haynes called the game "surprisingly deep and fun for such a simple premise".

"[6] GameZebo's Stephen Greenwell rated it 2/5 stars, stating it is "easy to pick up and play" but has "very repetitive gameplay" and "lackluster visuals and sounds".
