This intuitive slot which has been produced by Rabcat software has proven to be a bold move within the gaming industry as it is a highly entertaining game to play and all credit should go to Rabcat for having the confidence to put something like this onto the market.

It is one of those slots which keeps players interested as they will be eager to see how the story unfolds and how much money they will end up winning.

Theme and subject

Game theme

The theme of the Castle Builder slot, as you will probably already have guessed, is medieval and it is difficult to relate this game to any other playing experience.

The aim of the game is to build a castle and you can see this happening before your very eyes to the right of the reels.

This has the effect of keeping the player completely absorbed in the gameplay as they are not only concentrating on the reels but also on the castle which is being built.

The background scenery to the reels is what looks like a forest which in turn lends itself to a clearing in which the castle is being built.

It must be said that everything ties in perfectly and sets the player up for a slot playing experience that few other games are able to match.

As this is one of those progression type of slots where the player can work his or her ay up through the different levels is could be described as slightly addictive and a player could end up playing for longer than they first intended

Symbols and soundtrack

Symbols and sound

To be perfectly honest, you don’t even notice the soundtrack but instead of that being a criticism it is more like a compliment for the sole reason that you become so absorbed in the actual gameplay.

If you are someone who has experience playing online slots you will be only too aware that not many games will be able to boast that it is so engrossing to play there that they don’t even notice the soundtrack.

When it comes to the symbols, they have been designed in such a way that they are an absolute perfect fit for the Castle Builder slot.

Most slot players are used to the usual Ten, Jack, Queen, King and Ace symbols but Rabcat are having none of that and even though some of the symbols are similar to those just mentioned, they are in effect, completely different.

They comprise of the King along with his son and two daughters along with a pouch of money, a treasure chest, a door and a jewelry box.

There is also a building materials symbol which obviously relates to the building of the castle along with an architect which stands for the wild symbol.

It would be prudent to mention that on first sight, the symbols on the Castle Builder slot look to be slightly basic.

The vibrant effect when looking at the reels is not there and if you compared the symbols to those of something like the TED slot, you could be forgiven for thinking that the Castle Builders slot could be lacking in some way.

Thankfully though, this is not the case at all and if the quality of the symbol graphics is the only criticism, Rabcat have not gone far wrong with the design and production of this wonderful game.

Bonus options

Bonus options

Now we are talking!

The bonus options on the Castle Builder slot basically involve the building of the castle which, as we have already mentioned, takes place before your very eyes on the right-hand side of the screen next to the spinning reels.

In order to build the castle, you will need to get at least two of the building materials symbol to appear on the same pay line, the more you get, the better.

The maximum number of these symbols that it is possible to get is five and if you are lucky enough to get those you will be awarded gold value blocks, four of these symbols will result in silver value blocks, three will get you bronze value blocks and only two will reward you with standard value blocks.

If you are asking yourself, what is the point of the different kind of blocks the answer is that if you are using the premier building blocks the castle which you are building, when completed, will be worth more.

As you collect more building blocks in general, the building of the castle on the left-hand side of the screen will progress.

When the castle has been built, proceedings start to get more exciting when scene appears which shows the Kings daughter and you will be offered the opportunity of choosing a suitor for her from three which are made available.

Each one of these suitors stands for a different value and this is how the game continues because when the next castle has been built you will be able to choose another suitor for the Kings son or daughter.
