Castle War : Idle Island is a Castle vs Castle battler in PvP.
Build towers, craft cannons, engage mages & mercenaries to have the best Castle Island !

Rule your island, assign missions to your village. Build your Castle to fit your strategy, using the various offensive & defensive capabilities at your disposal.

Send your troops: Archers, swordmen and pikemen will lead the way to the gate of opponent’s Castle.

Archers : Archers are very poweful at shooting down shieldless pikemen, and will attack the enemy throne from afar. They are weak to normal troops.

Pikemen : Pikemen have longer melee reach than normal troops and are extra effective against them. Pikemen are weak to archers.

Swordmen : troops that will be sent out automatically to defend against enemy troops and to attack the enemy Castle directly.

Use Siege weapons: Ballista, trebuchet, catapult and cannon to destroy other’s Castle towers and weapon, and protect from their troops & projectiles.

Ballista : Straight shooting ballista is great for fast actions like taking down projectiles and infantry. Low damage and reload time.

Catapult : Catapult also known as the spoonager is the classic siege weapon. Offers moderate damage on a moderate reload time.

Trebuchet : Your best choice when you want to launch 90 kg projectiles over 300 meters. Longer reload time and heavier arc makes it best suited to rain down destruction on enemy structures.

Cannon : The highly destructive cannon shoots straight and fast but has a fuse time, and a long reload time.

Cast powerful magic: Call a meteor strike, invoke a powerful blackhole and protect your Castle with powerful arcane shields.

Starcaller: Calls a shower of meteors upon your enemy’s Castle.

Black Hole: Member of an obscure sect of spellcasters who feed exclusively on dew biscuits and hill brew. They have developed an ability to channel chaotic forces upon the battleground that pull with devastating force projectiles and any other material not bolted down.


Build a magnificent Castle: Use wood, stone and metal rooms, to build solid ramparts and impressive towers

Crystal Room : Fragile material that is resistant to elementals. It's magical resonance improves recovery of spellcasters, reducing all spell cooldowns. The effect is stronger for spellcasters residing within.

Iron Room : Sturdy and heavy material that is good where physical endurance is paramount.

Wood room : Simple wooden structure.

Stone Room : A balanced and durable material great for castle building.

Mix all of those elements to build your very own Castle, from a magic tower casting huge spells, a soldier swarm on the walls of your opponent, or a rolling thunder of spikes and stones crushing its ramparts.

Use the weapons workshop to transform your standard weaponry into a state of the art piece of engineering : increase rate of fire, projectile damage, projectile speed, or weapon durability.

Prove who is the better among your friends with the challenge mode, where you can battle with them and show who have the better Castle !
