About Castle Towers: Realm Defense
Mushroom goblins, orcs, ninjas, swamp trolls, stinging bees and ember fiends march down the dirt road towards your castle gate. Every one that slips through costs you a life.
Build on fixed tower spots: archer posts, barracks whose soldiers block the road, mage spires and bronze mortars. Upgrade each line three times, then choose one of two elite towers with their own powers — venom arrows, sniper shots, templars, berserkers, unmaking rays, chicken hexes, storm coils and seeker rockets.
Your knight hero walks wherever you tap and grows stronger in every battle. Rain meteors on big packs, call reinforcements, and send the next wave early for bonus gold. Earn up to three stars per level and spend them on 30 permanent upgrades.

How to play
- Tap a stone tower spot to build one of the four towers.
- Tap a tower to upgrade it, buy elite powers, move the barracks rally point or sell it.
- Tap the red skull at the road entry to start a wave — or to call the next one early for gold.
- Tap the hero portrait, then the road, to move your hero. Tap a spell, then the battlefield, to cast it.
Tips & tricks
- Barracks soldiers stop enemies inside the range of your other towers — put them where several towers overlap.
- Armored enemies shrug off arrows: mages ignore armor. Magic-resistant crawlers fall fast to archers and mortars.
- Mortars cannot hit flying enemies — keep archers or mages near every road.
