Castle Builder Free Spins

Castle Builder offers its own particular twist on slots by merging with it elements from world-building games such as those found on social networks (further details in Symbols & Features section). In doing so, it parts with the standard free spins mechanism found in many slots.

However, free play is always an option at most casinos. We can’t recommend this enough as it gives you the opportunity to familiarise yourself with the mechanics and gameplay of the game prior to committing real money to it.

Castle Builder Slot

Castle Builder is one of Rabcat’s more well-known slots with 5 reels, 3 rows and 15 pay lines. What makes it particular is that it integrates elements from social games, more specifically, the world-building-type, and a storyline to create more purpose, and in so doing, add entertainment value.

You take up the role of a castle architect travelling through 3 kingdoms and an empire. At every stop, you will encounter a king who assigns you the task to build a castle for each of his daughters. There are 3 kingdoms with 10 castles each, and another 5 to build in the empire.

As you spin the reels and achieve ‘building material’ symbols, you further the works on a castle project. After you finish a castle, the princess in question moves in, and a little matchmaking bonus game of sorts take place. There are 3 suitors, and you’ll play a ‘click me’ game. Each prince brings his riches and this can be small, medium, or large. Depending on who you choose to marry the princess off to, you will get a bonus win corresponding to the size of the suitor’s riches.

Once a castle has been build, that’s a stage cleared. You receive rank-up badges and rewarding achievements, and your status is bumped up the job ladder. The story progresses as you move onto the next building site in the kingdom.

Symbols and Features

Castle Builder features 5 reels, 3 rows and 15 pay lines. You have the options to set the bet level anywhere between 0.01 and 1 as well as the number of pay lines you want during the game.

Castle Builder tries to reinvent the ‘slots wheel’, so to speak, by adding elements from social video games – the world-building genre, in particular – such as building castles, an ongoing storyline, and a map that marks 3 kingdoms with 10 castles and an empire with another 5.

There are 8 types of symbols, 1 Wild Symbol and 4 Building Symbols (standard, bronze, silver, gold). The Wild Symbol replaces any other symbol apart from the Building Symbols.

Building Symbols are important to continue construction works on the castle, found in the left portion of the screen. On top of the castle, there is a completion bar showing just that. The Building Symbols can be standard, bronze, silver, or gold. The more noble metal symbols you collect in a pay line, the more the value of your castle increases. This, in turn, adds more value to each suitors pot of gold, garnering you bigger wins when you play the ‘click me’ game.

When a castle is completed and the princess whose the owner moves in, you play a simple game of choice. You have to choose amongst 3 suitors, each one richer than the other. However, you don’t know their monetary worth until after you’ve picked. After picking the suitor for the princess, you are given a bonus win depending on that suitors worth.

By completing a stage, you also get rank-up badges and rewarding achievements. This raises your level on the job ladder

Castle Builder Jackpot

Castle Builder does not carry a jackpot feature in the strict sense of the word. However, the ‘click me’ feature at the end of a stage is the closest thing. The value of the small, medium, or large pot of gold the suitors carry depends on the value accumulated when building the castle.

Also, if you get a pay line of 5 wilds, you’ll win 10 000 coins.

Castle Builder on Mobile

Castle Builder is made available across desktop, tablet and smartphones. On desktop, the game is available both in flash and html5. The game converts seamlessly to handheld devices utilising iOS, Windows, and Android.

Castle Builder RTP

Castle Builder is a somewhat low-variance game with a RTP of 96.47%.
