The physics projectile puzzle game that started it all returns with more smashing trebuchet action.

Download the full, free game now!

Embrace the cathartic power of structural carnage and a really, really big trebuchet with Crush the Castle: Siege Master. The goal in each stage will vary, but at its core the objective is all about crushing a variety of elaborate structures to smithereens.

The king has sold off all of the royal army to fuel his loot box addiction and you must use the only tool left - your trusty trebuchet - to fend off the invaders trying to take over the kingdom. From rolling green fields to deep deserts and beyond, smash into the enemy strongholds and take out its treasonous inhabitants.

Topple enemy castles and reclaim your kingdom. Tap once to swing your trebuchet, tap again to hurl its ammo.

The vibrant kingdoms are filled with a variety of fortresses to destroy.

Crushing enemy castles is satisfying, but wiping out the baddies inside is just as satisfying.

Boulders getting boring? Fill that castle with massive hooks or set it ablaze with powerful missiles.

Crush the Castle: Siege Master is completely free to play! While you can download and play for free, there are optional in-app purchases available to enhance your experience.

Catapults get all the glory, but can they use a counterweight to launch a 90 kilogram projectile over 300 meters? No. No they can’t. The trebuchet is the greatest medieval siege engine of the middle ages, and now it’s yours to enjoy anywhere, anytime, in the palm of your hand.

Excellent, challenging, rewarding

Reviewers saying it’s too hard and buggy and weapons are useless are expecting an Angry Birds kind of game that’s easy, mindless fun. These levels are creative and fun, but also really hard sometimes. They are not buggy or impossible. You can restart a level very quickly, which encourages trying again and again and you often do have to try many times. They can all be done but some levels take very precise shots, which is hard with a catapult. I’ve had luck switching which ammo I start with on some levels, so keep that in mind if you’re stuck.

I have literally laughed out loud at some of the levels. I’ve felt very clever once I three-starred some levels and I keep coming back to this game to see how creative the next level will be. Even if you have to keep restarting, the “enemy” is really funny and it’s hilarious what you do to them when you complete a level.

Ignore all reviews less than 5 stars. This is a great game.

Very good game

I finished all the levels and feel sad that there aren’t any left. While the game mechanics are very cool, accuracy in slinging the projectile can be pretty difficult, in some levels where accuracy counts sometimes I repeatedly make the same exact sling angle 5 times in a row, so it’s pretty hard to tell the progress of the projectile. Also I’m disappointed in how a gift purchase to get additional projectiles in a certain level is not permanent for that level especially since I like to play for all stars and if I mess up on any part of that one level I have to restart and lose my extra projectile. Otherwise it’s a very creative game where you decide how you want to bring the structure down, perhaps by the intended way, maby a more strategic way, or even an random lucky precision shot way. It’s up to you and the further into the game you go the more tools of destruction you get in order to make your creativeness spark 10 fold.

So. Many. Bugs.

Grappling hook is useless. Most the time it latches onto nothing thus doing nothing but wasting a shot.
Points system is “pointless” and frustrating. Numerous times I’ve destroyed almost everything including collecting packages, yet fell short by thousands of points needed to win. Yet on other occasions on the same level, I’ve destroyed far less but somehow got 3 stars.
All the button pressing needed when retrying a level is incredibly aggravating.
Was excited but very dissatisfied.
How about the issues with physics where a defender could be on top of a structure that falls but, falls down and is laying on the side yet still alive?!? Or the now countless times when I’ve seen objects strike something such as an exploding box, but does nothing?!?! If this isn’t fixed in an update then this company is crooked for making you want to spend money to defeat levels in their broken game. Why can’t we just buy a game, once, and not have to keep spending money just to enjoy something to pass time? Oh, because it’s greed in the mobile micro transaction game world is worth billions. Gross.
