Castle Builder Slots

Created by innovative casino software developers Rabcat, the Castle Builder Slot Machine is a highly established online slot game. The theme itself is centered on a medieval setting, where the player is required to go through a range of magical kingdoms. Along the way, a plethora of characters make an appearance, such as knights, mighty kings and of course, the princess.

Castle Builder slot machine overview

When you first load the game, you will notice that the slot-position is slightly unusual, as it is located to the very right hand side of the screen. To left of it, you get to see the castle in its current state. The Castle Builder Slot have made this game highly interactive, as the castle adds more layers to it as the game progresses.

This is ideal for those that like to remain entertained throughout the end-to-end gaming experience. The Castle Builder Slot offers players a respectable RTP (Return-to-Player) of 96.47%, which is fairly reasonable for long-term bankroll management. Moreover, there are a total of 15 paylines, which are available across 5 reels.

Rabcat Gaming have done a good job with their mobile optimisation, as the Castle Builder Slot Machine is available to play on both smartphone and tablet devices. This covers Android and iPhone models.

So now that we’ve covered the basics, in the next section of our Castle Builder Slot review we are going to explore the main features and bonuses in more detail. You can review a range of operators offering slots here.

Features, specials and symbols in Castle Builder Slots

The Castle Builder Slot feature can be quite daunting at first glance, not least because it utilises a completely unique approach. Before we get to that, let’s cover the wild symbols first.

The wild symbol is represented by the main ‘Castle Builder’ icon, who is an elderly man with a big moustache! As is standard in the online slot space, the wilds substitute all symbols apart from the bonus symbols. Furthermore, the wilds can only be utilised to form a win with standard symbols, not on their own.

Regarding the main Castle Builder Slot bonus game itself, this is divided in to 4 different levels. The higher the level, the higher the prizes on offer. To unlock the first level, you need to get at least 2 bonus symbols in a single payline. When you do, the feature is activated.

As the princess, you need to select 1 suitor from a potential 3. This can include a knight, price, leper and a frog, among others. Behind your selection is a range of cash prizes.

As you complete the first feature round, you will also see the castle increase in size to the left of the reels. In order to get to level 2, 3 and 4, you subsequently need to land 2 or more bonus symbols on a single payline. Every time you do, you upgrade to the next level. To clarify, the bonus symbols are represented by ‘Tools’.

As you progress through the Castle Builder Slot bonus game, not only does your castle get bigger, but the hidden cash prizes also increase size. This is a rather innovative approach to a slot bonus, which we really like. However, on the other hand, it can have the effect of drawing you in to extended gameplay, as you try to progress through each level of the game.

In terms of the maximum prize on offer, this is set to just 200x your stake. However, the RTP of 96.47% does mean that you have the chance to experience frequent wins. Below the jackpot pay-out, the next biggest wins can be achieved by landing the ruby chests, golden chests or the castle door. At the other end of the pay table, the smallest wins are represented by the princess, prince, queen and king characters.

So now that we’ve covered the main feature round, in the next section of our Castle Slot Builder review we are going to show you how to play.

How to play the slot game?

Firstly, it is important to note that whilst the Castle Builder Slot game has a lot going on, it is actually rather simple to play. All the feature rounds are clearly explained as you progress throughout the game. Moreover, you can also keep an eye on the feature meter at the top of the screen, which lets you know what level you are on.

When you find a suitable Rabcat casino that hosts the Castle Builder Slot, you then need to determine how much you want to stake per spin.

Your first port of call is to select the total amount of paylines you want in action. This can be a maximum of 15, right down to just a single payline. Next, you then need to select how much you want to bet per line. This can be selected at a minimum of 0.01 per line, up to a maximum of 1. As the bet size is multiplied by the amount of lines in operation, the maximum bet per spin is $15.

To double-check that you are staking the correct amount, look at the amount displayed above the ‘Bet’ tag. To get the reels spinning, you need to click on the spin button. This is a ‘Red Circle’ that sits in-between the ‘Lines’ and ‘Bet’ buttons.

If you don’t want to keep pressing the spin button manually, you can instead use the auto play feature. This allows you to sit back and let the Castle Builder Slot Machine do the work for you. The auto play feature will stop when you land the main feature, which ensures that you get to enjoy the game.

Other than that, there is nothing else that you need to be made aware of. If at any point of the game you want to double check how much a particular symbol pays out or you want further clarity on the bonus round, click on the ‘Pay Table’ button.

Castle Builder slot machine summary

In summary, the team at Rabcat have really flexed their innovative muscles with their Castle Builder Slot title. The game takes you through an ongoing journey that issues rewards as you progress further throughout the game. This makes the Castle Builder Slot stand out from the crowd. This is especially true for those that like to play feature-rich slots that provide an enhanced player experience.

When it comes to the jackpot, although this is relatively low at just 200x, this is slightly countered by the RTP of 96.47% that is on offer. Arguably, if you are chasing that life changing win, then the Castle Builder Slot will not suffice.

However, if a combination of exciting graphics, gameplay progression and an interactive experience sounds up your street, then the Castle Builder Slot is definitely worth a try!
