About Castle Builder Slot

Castle Builder is an innovative online slot launched by Rabcat many years ago. It’s a combination of an online slot and a level-up castle-building style across 3 different worlds. The game plays on 5 reels, 3 rows, and 15 paylines, with betting options ranging from £0.01 to £50 per spin.

When playing the Castle Builder slot, you’ll be in the role of a royal master-builder who has to create castles for monarchs in 3 different kingdoms. The building process happens by spinning the reels and gathering construction material symbols. The goal is to build 10 castles in each kingdom.

Design, Symbols and Graphics

When you first launch the Castle Builder slot, you’ll notice that the reels are on one side, and the castles are on the other. Don’t worry - the setup works perfectly across desktop and mobile devices! The game has a high-end design with fantastic visuals, showing the kingdoms in the background.

The Castle Builder slot has 8 building symbols and 1 wild symbol. The building symbols include a vault, a big treasure chest, a small treasure chest, a bag of money, the king, the princess, the prince, and the maid. The wild substitutes for these symbols to help you form winning combinations easily.

RTP, Variance and Payouts for Castle Builder Slot

Castle Builder has an RTP of 96.47%, which is above the industry average of 96%. It has a low-medium variance, resulting in more frequent and lower-value payouts. The maximum payout in the game is 1,000x your stake.

Gameplay and Features on Castle Builder Slot

As you can see, Castle Builder has an unusual gameplay where the aim is to build castles by spinning the reels.

The building process goes by landing symbols on the reels. You’ll notice how the castle starts building on the left side of the screen as you land more building symbols. There’s also a progress bar showing you how much you have to build.

The building symbols come in different qualities (standard, bronze, silver and gold). The better material you build with, the more worthy the castle will be. When the castle is completed, the princess moves in and has to choose from 3 admirers.

So, how does the princess choose her admirer? You need to pick from the options where you can win some nice payouts too! Each admirer will match the value of the castle. However, you don’t know how much each admirer is worth after you’ve picked one.

Each castle is bigger and more worthy 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 castle, you’ll have the chance to receive special achievements from the respective king. In doing so, you’ll work your way up by achieving higher ranks and unique service medals.

Castle Builder is a fantastic game! It has unique gameplay where the aim is to build castles in order to win. It’s not a standard slot, which is the reason why some players might find it difficult to play. But if you’re into innovative slots with a different take on the gameplay, I recommend you try this game from Rabcat.
