Rabcat has made some excellent slots over the years but not many of them come close to the innovation and uniqueness that Castle Builder 2 provides. Released just this year, this online slot is definitely among the more modern releases that we have seen and once you have played it for yourself, you will see why.

Following on from the original Castle Builder slot that was hugely popular with players, this sequel has come with improved graphics and bonus features that we are sure will also be appreciated by the players at the online casinos. Additionally, the rewards on offer are bigger too – so essentially this is a bigger and better version of the original.

Classed as something of a cross between an online slot, a social game and a mobile game, Castle Builder II will have you building castles in order to level up your chosen character and thus improve the rewards as you progress.

Castle Builder II has 5-reels, 15-paylines and is an instant-play slot that is played through the browser using HTML5. A return-to-player percentage of 96.74% is pretty decent and with a medium variance, you are never going to be too far away from the action.

Every time you play the game it will be different to the last and no two players will experience the game in the same way. Read on to find out more about this excellent online slot by Rabcat.

Containing 5-reels and 15-paylines, Castle Builder 2 offers similar gameplay to that of the original and will have you following a storyline as you construct as many as 70 medieval castles across 15 different kingdoms.

As you start out you are first tasked with choosing one of three characters (only two can be chosen until you have completed the progression of one of them which then unlocks the third). You then choose the location you want to play from on the map and this is when your game will kick into action.

You will have to progress through the game through finding the various symbols in winning combinations that will not only payout to your account but will also be collected as the materials for you to build your castles.

Every time you complete winning combinations that contain the various construction materials, a small grid to the bottom left of the screen will fill up a little more. Once you have filled this grid up completely, a certain part of the building you are building will be completed.

Once you have progressed far enough to complete eight of these grids, this is when you will be able to complete the castle in its entirety. You then choose a new location to start building another castle and once you have completed all locations with a character, you can then choose another character and repeat the process again.

Graphics and Sound

What you will notice from Castle Builder II is that they have definitely ramped these up compared to the last game. The graphics and animations, in particular, have been improved massively and are much smoother and sharper than they were the last time around.

All of the symbols on the reels have been drawn extremely well and the high definition really makes this game a beautiful one to look at.

As for the layout and the background of the game, both are quite similar to the original but have been done in a higher quality. The reels are once again located to the far right of the screen in order to leave space for your currently building castle. You actually get to see the physical improvements each time as you progress through the game.

As for the sound effects in Castle Builder II, these do very well in adding to the immersive effect of the game. These can be turned off if you prefer but we actually like them as they add to the complete feel of the game.

Base Game Symbols

Another thing we like about Castle Builder 2 is the fact that there are no non-bespoke symbols such as fruits or playing cards symbols. Every symbol is related to the theme and most of them will play a part in your progression through the story and building aspect of the game.

The symbols that are the most important are the stone, brick, slate and granite as these are the building materials you will need to build the castle. Every time they are found in winning combinations, you progress a little bit further in the game.

Other symbols on the reels include gold bars, treasure chests and crowns. While these symbols will not aid you in your castle building quest, they will still bring you some much welcome payouts when they help to create winning combinations on the reels.

Wild Symbols

Whichever character you have chosen to represent in the game will also be the wild symbol on the reels. There is nothing fancy about these wild symbols as they will just do what you might expect and substitute for most other symbols on the reels.

The only symbol they will not substitute for in order to help create winning combinations is that of the free spins scatter symbol.


Scatter Symbols

Scatter symbols are what will are needed to unlock the free spins round on Castle Builder II and we will tell you more about that in the next section. These symbols are represented by a pink symbol that has the word ‘freespins’ written on them and they will not pay out if found in a winning combination.

Free Spins

Castle Builder 2 also has a lucrative free spins round that players can take advantage of. This is activated when the free spins scatter symbol is found anywhere in view on your reels at least three times. Three of these scatters will give you ten free spins while four and five will bring fifteen and twenty of them respectively.

There are no multipliers or any other bonuses added to this round which is a little disappointing but they are still free spins nonetheless. Who is going to say no to some free spins of the reels and a chance to further complete their castle build?

Royal Wedding Feature

Once a player has managed to completely build a castle they are awarded the Royal Wedding Feature. Your character will have gained a lot of admirers along the way when building the castle and you get to choose one of them in order to receive a random cah prize.

These prizes will increase the further you get and the more castles that you build but in the beginning, they are quite minimal. This is a good little feature to aim for and will definitely get better as you progress and build bigger and better castles.


Betting and Payouts

Placing bets is pretty straightforward on Castle Builder II as you just have to decide on the number of lines to bet on and the coin value as well as how many coins per line to bet.

You have a choice of coin value that ranges between 0.01 and 2.00 which essentially means you have a betting range of between 0.01 and 30.00 per spin. That max bet is obtained when you use the full value for the coins of 2.00, use two coins per line and bet on the full 15-paylines available.

While a max bet of 30.00 is considered quite low for an online slot, we feel that this is because this slot is designed for long-term play. High-rollers might not like it but there are plenty of other slots out there that will accommodate them.

Why Play Castle Builder II

If you have played the original Castle Builder and had a great time, you are going to love the improvements that this sequel has made. Let’s not forget that the original was an award-winning slot, so for this one to now have a lot of additions and improvements, you can just imagine how good it is.

This is an online slot that is designed to be played for long sessions so if you are looking for a slot to enjoy a couple of spins on, you might want to look elsewhere. If however, you are planning an extended session of slot playing at the online casinos, this is the one you should be playing.

To sum it all up, we love the progression aspect of Castle Builder II and the fact that your rewards will be greater the longer that you play. We also appreciate the work that has been put into the graphics, the storyline and the sound effects which all play their part in making this such an enjoyable slot to play.

You will never get bored on Castle Builder II and we just know that most of you are going to love it when you check it out. If you are still not convinced, go try it out for free before deciding if you would like to play it for some real money at the online casinos.
