About Castle Builder II

Castle Builder II is the second online slots game in a series of the popular game. The game is set in a fictional province and is centred on many suitors trying to win the King’s daughter hand in marriage. Players work towards building the best castles and hope to win the available lucrative prizes. Unlike most other games, Castle Builder II allows you to choose your preferred avatar before commencing to play the game. The three avatars are Sam, Mandy, and Igor. Sam comes in handy when you need to construct castles quickly while Mandy triggers a scatter symbol which is essential in landing the free spins. Igor on the other hand turns the entire reel wild.  The first two avatars are initially available to players, but the latter requires you to win the game to unlock it.

Symbols incorporated on the reels include different building materials, the King, the crown, and numerous treasures. The King is the top paying symbol.

All you need to do to win one round is to build a magnificent castle. The castle is built by collecting building materials such as blocks and iron ore in the symbol collection feature. The building material obtained from any winning combination is collected and indicated in the symbol collection meter. Once it is full, a building block is created until you complete the building.
