Castle Builder II is a slot from Rabcat that was released in 2017. The requires players to work their way across a fantasy world, building ever more elaborate castles for princesses in exchange for bonus payouts, free spins, and great rewards. It is a truly unusual slot and one that can provide hours of fun. Read on to learn about all it has to offer.

Castle Builder II - Slot Features and Rewarding Levels

At its heart, Rabcat's Castle Builder II is a 5-reel slot with 3 rows and 15 fixed paylines. This means that regular payouts are awarded when enough matching symbols land along a payline on adjacent reels starting from the leftmost reel.

However, around this standard slot machine is a huge fantasy world that people need to navigate as they play. Players need to select which character to play as, and as they spin the reels, they will also be constructing castles to attract suitors for the princesses.

There are four levels that can be reached in the Castle Builder II slot, each more volatile and potentially rewarding than the last. In total, the game features more than 300 characters and requires players to build 75 castles across 15 kingdoms. There are also cup challenges offering trophies, the ability to increase avatar skills, free spins to be won, and more.

While this may sound complicated, the gameplay is actually very simple, and all is explained in this review.

Enter the World of Medieval Strongholds and Beautiful Princesses

Castle Builder II takes players through various different locations, and each one is brought to life through different graphics, animations, soundtracks, and sound effects. The map of kingdoms has a distinctly medieval feel to it, but the locations themselves are highly varied and include a variety of different landscapes. The characters are also somewhat varied; some feel very modern, while others are clearly ancient.

All of the slot’s symbols are thematic. Your chosen character acts as the wild symbol, while the high-value symbols include a crown, a treasure chest, a gold ingot, and a ring. The lower-value symbols are building materials, wood, bricks, granite, and iron ore. There is also a simple ‘Free Spins’ scatter symbol.

How to Play Castle Builder II?

While the Castle Builder 2 slot sounds complicated, playing it is very easy. Upon loading the slot, you have to choose from three different characters. Initially, you can choose from building expert Sam or female builder Mandy. The third character, Igor, is only unlocked once you have completed a game cycle with one of the other two characters.

You then need to choose a location and are taken to the reels, where you simply need to set your total bet per spin before spinning the reels. You will find all of the functionality you would expect in a video slot, such as autoplay and a max bet button. As you spin the reels, various achievements are unlocked, and bonuses are awarded. All of these features are explained in detail in the next section so that you fully understand what is happening as you play.

Castle Builder II - Bonus Features

The slot is all about building castles, and as mentioned, the lower-value symbols are different types of building materials. Whenever you land a winning combination of one of these symbols, it is collected in a meter. Once the meter is full, a section of a castle is built to the left of the reels. There is a larger meter at the top of the screen that shows your overall progress for the castle. As you build the castle, admirers may turn up and increase its value

When a castle is complete, the princess moves in, and you must choose her as a suitor. In exchange, you will receive a cash bonus prize. The game has several levels and kingdoms to work through. You begin in the Bronze Cup challenge, and there are four to work through (Bronze, Silver, Gold, and Diamond). At the Bronze level, you need 6 building materials in the meter to complete a part of the castle.

At the Silver, Gold, and Platinum levels, this increases to 9, 12, and 15 symbols, respectively. The higher the Cup level you are playing, the greater the possible rewards. There are 15 kingdoms on the map, and you need to finish 9 of them to complete a Cup Challenge.

In addition to the castle building feature, there is also a traditional free spins round. Landing 3, 4, or 5 scatter symbols will award 10, 15, or 20 free spins, respectively. The free spins cannot be retriggered, but you will continue building castles throughout them.

Slot Playing Tips and Strategy

Castle Builder II is not a game for those looking to play just a few spins. To fully unlock the game’s potential, you will have to play a huge number of rounds, possibly many hundreds of them. It is important that you consider this when deciding if it is the right game for you and setting your bet per spin.

If you would rather play a more traditional slot, then we would recommend Rabcat’s slot Robin of Sherwood. It offers a number of rewarding features together with entertaining graphics and animations, but the gameplay is far less involved.

Castle Builder 2 Slot on Mobile

As with all of Rabcat’s slots, Castle Builder II is fully mobile-compatible. It has been developed using HTML5 so that you can load it directly in a web browser on all mobile devices without the need to install any special apps. The graphics and animations are optimized for smaller screens, and the controls are also mobile-friendly. Thanks to this, you can continue your quest to build the best castles whenever and wherever you wish.

New and Exciting Gaming Experience

Castle Builder II is not a slot that everyone will enjoy. However, if you are the type of player that enjoys progression within games, then you are likely to have a great time. It doesn’t actually take long to build a castle, so there is always something going on, and the bonus features are truly rewarding. Furthermore, the in-game texts introducing characters and kingdoms are genuinely entertaining. We recommend everyone tries the demo of this slot at the very least, so they can discover for themselves what it is all about.
