Castle Builder is one of the most popular slots from Rabcat, which is a fast-rising developer of online slots. The slot was so popular that Rabcat released a new and improved version, Castle Builder II. Even with this, the original is still very impressive. The medieval and adventure-themed slot greets players with a welcome message about going on a journey to great kingdoms and building castles for beautiful princesses. The slot also follows a storyline starting with Forana of the Kingdom of Gracious asking you to build a castle for his daughter. Then, as you land building symbols on the reels, you will be building a castle on the left side of the screen. The Castle Builder slot does not offer free spins or multipliers but there are unique bonuses like the castle building and royal wedding. You can dive into medieval greatness with the Castle Builder slot for free here at GoodLuckMate.

Castle Builder

How to play

The Castle Builder slot is played on five reels and three rows, with the reel set located on the screen's right side. The slot also features 15 adjustable paylines, so players have the chance to land up to 15 winning combinations, but they can choose to play with only one payline active as well. After selecting how many paylines you want to play with, you also have to choose a bet level/coin value between €0.01 and €1. This leads to a total betting range of €0.15 to €15. The betting range is low, so the game might not appeal to high rollers.

Once your preferred bet size has been set, you can press the spin button. All the winning combinations in this game are created from left to right and on any active payline. If you want to bet with the maximum amount of paylines and bet amount directly, you can click on the bet max button.

Symbols and payouts

The symbols on the castle Builder slot's reels fit the medieval theme with members of the royal family and treasure chests, offering you exciting wins as you play. There are also building symbols, but these will be explained further down in this review as we go over the game’s bonus features.

The highest-valued symbol of the slot is the older man, which besides acting as a wild symbol will give you a reward of 20,000 coins for landing five on an active payline. Next is the door to the castle, which offers a payout of 20,000, 2,000, and 200 coins for landing five, four, and three symbols across the reels. Then, the massive golden treasure chest symbol offers a reward of 1,000, 200, and 25 coins. The smaller treasure chest symbol with rubies around it will give you 500, 100, and 15 coins for landing five, four, and three symbols from left to right. The bag of money will then give you 250, 50, and 10 coins.

The lower valued symbols are members of the royal family, starting with the King. This symbol will give you 100, 50, 8, and 5 coins for landing five, four, three, and two symbols on a payline. Next is the Queen symbol with a reward of 75, 25, 8, and 4 coins. The prince offers a reward of 50, 10, 5, and 3 coins, while the princess will give you 10, 5, 3, and 2, coins for five, four, three, and two symbols. Although the symbols might seem high paying, keep in mind that the slot offers a very low betting range, and the value of the prizes are determined by the bet level/coin value.

Best Castle Builder bonus features

There are a few Castle Builder bonus features and these are woven with the slot's gameplay and offer exciting prizes. As previously mentioned, the slot features a wild which can replace the other symbols on the reels to form a winning combination apart from the building symbols.

Then, the building symbol is an essential part of the game. It comes in standard, bronze, silver, and gold symbols. You need to collect two standard symbols, three bronze symbols, four silver symbols, or five gold symbols on any of the paylines to build a castle on the other side of the screen.

After you have finished building a castle, you enter the Royal Wedding bonus. Here, the King's heir will enter the castle and choose from three admirers. You never know the prizes the admirers will give you until you choose a spouse for the heir. Among the three, there will be poor people (small payout), average citizens (medium payout), and wealthy nobles (high payout).

Unfortunately, there is no Castle Builder free spins feature to look out for. However, what makes this game unique is the achievements feature, giving the player a chance to achieve higher ranks and service medals while enjoying a fun video slot.

RTP & volatility

The Castle Builder RTP is way above average, set at 96.47%. It also features low to medium volatility, which means that you can expect quite frequent wins of decent values.
