"Protecting a castle has never been more fun, and if you’re expecting to put this puppy down after a few minutes, think again."

"There's no shortage of strategy in this delightfully unique tower defense game!"

"[CastleMine]’s deep upgrade system, tons of missions and digging mechanic offer a lot worth checking out."

"I don't recall ever coming across [a tower defense game] that's quite as strategic as CastleMine."

Defend your castle from the evils that lurk below in this unique strategy game! You will need to dig deep into the earth to uncover treasures and destroy the enemies threatening your castle.

Your foes will follow the path you dig so you must decide… Will you dig long and winding paths to slow your enemies down? Will you dig in search of treasure to help improve your defenses? Or will you dig up the cursed skulls that increase the power of your enemies but grant you greater rewards? These are the decisions you must make as both you and your castle grow in power!


• A player skill tree featuring 165 upgrades across 33 unique skills.

• Upgradable defense towers that gain XP as they fight.

• Strategic support towers that improve adjacent defenses.

• Unique strategy options where you control the path your enemies take.

• 60 challenging levels.

• Digging. Everybody loves digging.

    This is a truly free game first set through. I love that it allows you to adjust the skill sets after you place them. I also love that it allows you to replay levels and earn experience that way. I do wish there were more ways to get crystal, but this does add to the challenge.

    In the world of tower defence, it's difficult to be original and challenging - this IS both of those things, enjoy!
