Special Features

Castle Builder II is a slot game with many special features, that are designed to develop the storyline of the game.


Players must first pick an avatar from three characters – Sam, Mandy and Igor.


Players must then select one of the 15 kingdoms from the map where they will begin building a castle. These kingdoms include huge deserts, tropical islands, peaceful provinces, snowy mountains, kingdoms in the sky and more.

Cup Challenge 

The game includes four Cup Challenges – Bronze, Silver, Gold and Platinum. Players need to finish 9 of the 15 kingdoms to move up to the next level. The levels become more challenging as you progress, with the more challenging levels also offering higher winning potential. Players require 6 building materials to complete the Bronze Cup Challenge, 9 to complete Silver, 12 to complete Gold and 15 to complete Platinum. 

Castle Construction 

Spinning up a winning combination of one of the building materials, will add a block to your pallet. A full pallet will add a section to the castle you are building. Each castle needs eight sections to complete it and your building progress can be seen on the building metre across the top of the screen. 

Royal Weddings 

Each time a castle is completed, a Royal Wedding will take place. Admirers will come looking to marry the princess, with more admirers the more castles have been built. Pick one of them for a cash prize. 

Free Spins Round

Spinning up 3, 4 or 5 free spin scatter symbols anywhere on the reels will activate the free spins and players will receive 10, 15 or 20 free spins, respectively.

Graphics and Sounds

The game is visually attractive showing off the kingdom of King Lornquer III in which you are playing. This is visible around the reels which are situated on the right side of the screen. The castle that is being built can be seen in its various states of construction to the left of the reels, while the building pallet is situated in the bottom left corner of the screen and the building metre is above the castle.

Bottom Line
