  • Note: While there is not a Palace restriction on Ships upgrading to level 3 when the Palace is level 2, there is a resource storage capacity limit that makes upgrading to Ship Lvl 3 impossible. See the entry on Ships.

Princess DefenseEdit

When you complete the Single Player Campaign scenario #16 with at least one star and the destruction of the Princess's prison, the Princess becomes a member of your city's population.

When you upgrade the Palace to Level 3, the Princess will take shelter in the Palace during an attack and climb to the roof. From there, she will occasionally fire blasts of purple magic at enemies that come within a certain range of the Palace. These blasts deal a medium amount of splash damage around where they are centered. You cannot control where the Princess fires. She tends to target the closest opponent to the palace. She does not target Troops that are directly next to the Palace.

Survivor BenefitsEdit

Once you have created the Ninja Tech there is a chance that when the Palace is destroyed, you will recieve a Surviving Ninja Bomb which will then proceed to blow up your opponent's troops. 

Other Defensive StrategiesEdit

The Palace is your main building. If it is destroyed, your opponent gains an automatic star, and a victory. This can prevented by keeping your palace in the center of your Kingdom, or in other places that the opponents cannot reach. 

You can also put your Palace in an easily accessible place to gain a 12 hour shield once it has been destroyed.

About Palace LevelsEdit

Palace level means everything. The higher palace levels the more penalty applied to fight lower palace levels in addition to higher gold cost for attacking/new opponent Level 1: Level 2: Level 3: | Level 8: 600 gold Level 9: 800 gold | Level 12:

In addition attacking a lower palace level results in gold/sushi penalty in addition to earn less runes in the rune event. You may earn negative runes if the palace your attacking is a greater difference than 3 or 4 depending on event statue level.

although it unlocks new buildings, access to higher level buildings. It also ramps up the difficulty and time in this game convincing players to reach higher trophies to fight with the same level as well as spending more resources to upgrade/create buildings

Matchmaking is DEPENDENT to trophies not higher palace levels.


  • The palace takes the longest time to upgrade and the highest upgrade time (17 Days)
  • When the blue princess die, there dying sound is the same as the assassin dying sound.
  • Fishermans and gold collectors tend to run into the palace when under attacked.
  • Palace has the most health in the game as well as adding the most % damage.
  • When looking at your base, princess and (colored) princess roam around your kingdom
