How to play

The centrepiece of this exciting and enticing game is the building of castles. The player has to move around kingdoms amassing fame, fortune and power by building castles from materials available.

The game starts with the three characters, Sam, Mandy and Igor, each with different storylines to explore. You have to complete a game cycle with Sam or Mandy before you can unlock Igor.

The number of building blocks needed to complete one castle ranges from 6 to 15. After building each castle, you can help the princess get married by introducing her to suitors. If the wedding is successful you get more bonus.

Symbols and payouts

There are 9 types of symbols, including 1 Wild Symbol that can replace all other symbols, and 4 Building Symbols that cannot be replaced.

The low paying symbols are also the building symbols. They are Wood, Brick, Granite, and Iron. You have to pay attention to them because they will be the basic materials for building your castles. They can be found on the left portion of the screen. 

They can also come in different forms like standard, bronze, silver, or gold. The more valuable the metal you collect for building, the higher the value of your castle when completed. The high paying symbols are Ring, Gold Brick, Treasure Chest and the Crown. 

After each castle is completed, there is a pick-and-click game in which players can win up to 300 times of their bet. In this game, you have to choose a rich suitor for the princess you built the castle for. You are given a bonus win depending on the winning suitor’s worth.
