Build towers, save money, learn spells, and keep the enemy away! Follow the exciting story of the dwarven kingdom's eternal struggle against the troll hordes, who want only to crush the dwarves and claim their territory. To defeat these monstrous hordes, you must construct defensive towers and units and learn to wield powerful spells. Tap anywhere you like for a handy pop-up menu listing all the units and structures that can be built in each location. Tap existing structures to see how you can upgrade your forces with powerful improvements! All your towers and units have specific stats: Damage, Fire rate, Damage radius, Damage type, as well as various other features, such as Enemy Slowdown and Damage Over Time. Each level also brings new units and structures to help you fight the troll menace. You’ll never be lacking for new and exciting ways of decimating those nasty trolls!


Great game

So the defense and the monsters are really nicely designed however the towers need a little more upgrading for example for the first tower when you upgrade it to the last level it should have some effect upgrades like idk splash slow or instant death some nice effect would make this a very very nice defense plus u guys need stronger monster its really easy and for people complaining that sometimes u don't even have enough money to build a tower it's a strategy game morons that's something u need to figure out how to get money . Anyway I loved it worth the money keep it up guys

Great game!

Fun and interesting.

Love this game

Fun and challenging


Good game needs more levels

Fun but glitchy

Although I've had fun playing this game I don't feel it's worth the $3 I payed for it because many of the levels are glitchy, sometimes I will start a level with about 100 gold and then ill restart that same level and have 0 gold to start and randomly receive the 100 gold I should've had at the start after I lose half of my castle life. Very frustrating.

Great game!

Royal Defense is along the lines of Kingdom Rush except on this game I have to think and do math. Haha The nerve!! Hurry up with more content!!

The new fix needs fixing

The new graphics work, however the new 10 levels will not open. I get error message when I try to click on it.

Difficulty ramped way up

Levels that I was able to beat are now impossible. The game spams 100's of self healing units. Please fix!

New map?

The maps/levels you just came out with, I can't open or purchase it.... So how can I play? Overall great game though.

Good game

Can't open new update....
