Castle Builder II is an unusual slot in terms of features, but when it comes to the basic set up, it doesn't stand out from the crowd much. It's played on the usual 5x3 matrix and has 15 ways to win, which is something we have already seen numerous times before. Note that the number of paylines is fixed, meaning that you'll always have to bet on all 15 of them.
The betting range is also around industry average, even maybe a bit less than what we would have liked to see. It starts from £0.15 per spin, while the max bet is £30. If you find it annoying to press 'spin' button all the time, be free to use the autoplay. It allows you to set up to 100 automated spins in one batch, but there isn't an option to program it to stop, so you'll have to do it manually.
This game can have an RTP between 95.5% and 97.5%, depending on where you play. It means that Castle Builder II slot can go from highly favourable to a less rewarding game. That's why we believe this slot is much more suitable for experienced players who already know how to deal with complex games. But keep in mind that RTP is calculated over thousands of spins, so if you're planning to play any less than that, it won't affect you almost at all.
Also note that Castle Builder II is a highly volatile game, meaning that you won't score too many wins. But once you get lucky, the payout could be huge. This is all because of the specific gameplay, which is set in a way to make players spin more and climb the levels to compete for bigger rewards.
We are used to seeing classy looking games coming out of the Rabcat workshop, and this one is no different. Castle Builder II slot has a colourful, cartoonish look to it, with lots of vibrant colours and detailed artwork. As you move through the game levels and choose different characters, you'll see fundamental changes in the game design, from various backgrounds to different reels designs.
Because of the interactive game mechanics, there are quite a few moving parts on the screen. They all work very smoothly, making Castle Builder II look more like a Clash of Clans type of video game rather than an actual slot. However, note that this design and gameplay are not completely unique. There are several similar games, like Castle Pillager by Cayetano or Castles in the Clouds by Games Warehouse.
The music also feels like it came out of some popular video game. It's quite lively and cheerful, so it gives a positive vibe to the whole game. Apart from that, you'll hear a range of the usual slot sound effects when you score a winning payline, as well as a variety of drilling and hammer-kicking construction noises as your castle is getting build.
High-paying symbols are a treasure chest, golden bar, ring and a crown, so basically everything you would expect to find at an average king's castle. The rest of the lower-paying symbols are building materials, such as wood, brick, granite and iron ore. They may bring smaller instant payouts, but you'll need to collect them in order to build your castle, which makes them just as important.
There are both wild and scatter symbols in Castle Builder II, and they do all of the usual stuff. The wild, which is the face of the character you're playing with, can substitute for any other symbol apart from the scatter, while the scatter triggers the free spins round. We'll talk more about all of that in the following sections.
The Castle Builder II slot brings quite a few exciting features to the table. As soon as you start the game, they'll ask you to pick a character. There are 3 avatars to choose from, starting with the old building expert Sam and charming yet skilful Mandy. The third character is Igor, but you'll have to finish a game cycle with Sam or Mandy to unlock him. Note that, even though Sam has better skills in terms of building a castle, the Free Spins symbol only occurs if you choose Mandy.
There are a bunch of options to explore in this slot. It offers 15 different kingdoms, however, you'll first have to unlock most of them. As you play and move through the realms, you'll collect experience points and level up your character. Each new level unlocks a whole new world of possibilities, with improved bonuses and fresh offers.
Once the base game starts, you'll have to collect the materials we mentioned above to build your castle. Each time you score a winning payline with any of the building material symbols, they will be transferred to a meter below. When you collect 6 material symbols, a part of the castle will rise up before your eyes. Then you just repeat this until the castle is fully built.
Note that as you progress through the levels, you'll need more and more materials. You start in the Bronze Cup league, which is the basic level that has a 6 spot meter. There are also Silver, Gold and Platinum leagues that require 9, 12 and 15 material symbols to start a castle. However, with higher levels come heftier prizes! Note that you'll need to finish building a castle in 9 kingdoms to level up.
As you construct the building, you'll attract suitors. Once the castle is complete, the princess will move in, and you'll have to choose a suitor for her. Each of them will get you a particular cash prize, so choose carefully. But like in real life, they won't reveal their wealth before you pick them, so choose carefully.
Casino Builder II slot game offers a very basic free spins feature. You need to land at least 3 scatters to trigger the bonus round, with an option to get more spins for 4 or 5 scatters. Keep in mind that the bonus can't be retriggered during free spins. There are no surprises here, just a good old FS round we have all seen many times before. Here is how it goes:
