Level-based-slot feature: the player slips into the role of a royal master-builder who has to create castles for monarchs in 3 different kingdoms. The building progress is driven by spinning the reels and gather construction material symbols. The goal is to build 10 castles in each kingdom. After completion of a castle, the king's daughter moves in and has to choose from 3 admirers. A very important decision, as each admirer reveals his riches not before the royal wedding! Just as in real life there are poor fellows (small win), average citizen (medium win) and really rich guys (high win). Each castle is bigger and more pompous than the previous one and takes more construction material to be completed. The bigger the castle, the richer the admirers who ask for the princess's hand in marriage. With every accomplished building mission, the player has the chance to receive special achievements from the respective king. In doing so, the player works his way up by achieving higher ranks and unique service medals.

How to Play Castle Builder

The prize you get for a completed castle project depends on the materials you use in the building. In other words, the symbols featuring building materials are the most important elements in the Castle Builder slot game. There are four types of materials in the game and their quality depends on how many symbols there are in the winning payline.

You receive standard materials for two-lined symbols. Three symbols in a row will provide you with bronze materials. Silver materials are awarded for four-lined symbols and five-of-a-kind on a payline will bring you the most precious building material – gold! The coloured bricks in the line of building progress show what materials have already been used. The better the materials of the castle, the higher its value. Unused building materials will be saved for the construction of the next castle.

After construction is completed, you will get one of the three stacks of gold, which increase with each brick you lay for its walls. You can check the stacks’ current volume under the progress line.

The Wild Symbol of the Castle Builder slot is the castle builder master himself. He substitutes all the symbols except the building materials. The most lucrative symbol of the slot is the Locked Door. Five doors on a payline will multiply a line bet by 20,000. The other high-paying symbols are two types of Golden Chests, which give x1000 and x500 multipliers to a line bet when five-of-a-kind show up on a payline.

There are fifteen maximum paylines available on the Castle Builder slot machine. You can adjust the number of active paylines from 1 to 15, as well as the volume of a line bet in the range between 0.01 and 1.00 with arrows under the reels.

The spin button with a round arrow is under the third reel. Autoplay is switched on and off by a button near the spin button. You can set the number of auto spins and also turn on a fast gameplay mode.
