Online slots developers are getting more and more in tune with gaming trends. As such, we are seeing more slots games with unique modern gaming features and bonuses that are based on popular social games.

Castle Builder from Rabcat is one such game, which uses elements based on titles like CastleVille.

Base Game

The game begins with the set of reels alongside a construction site. For every winning combination that includes the construction tools, more sections are added to the castle.

A metre along the top lets you know how many more winning combinations must be made before you can win. The more construction symbols that appear as part of the combination, the more progress your castle makes.

In some cases, there will be construction symbols already placed on the reels when construction begins. When this happens, parts of the castle are built without the player having to spin the reels.

If you’re really lucky, you won’t even have to make a wager! As you spin the reels, three mystery people symbols at the top of the screen accumulate prizes. These will be used in the Royal Wedding Bonus.

The Royal Wedding Bonus

After the castle is built, the player triggers the Royal Wedding Bonus. You pick from three eligible admirers to marry the princess or prince. The prize is determined by your winnings during the previous base game.

Those three? symbols at the top of the screen correspond with one suitor, and the prize is awarded when you pick one to marry the royal bachelor or bachelorette.

Anything Else?

Well, that seems to be about all there is to Castle Builder slots. While it is a fantastic premise, it does get quite repetitive after a while. There are only so many times that we want to play matchmaker for one of the king’s heirs. This game could really benefit from additional bonus features.

Would We Recommend It?

Certainly. It really is worth a spin at least to get through a few Royal Wedding bonuses. Overall, the prizes are very generous, but it does take quite a bit of spending to complete a castle. Winnings from the Royal Wedding can definitely offset the costs – but you have to choose the wealthiest suitor (sort of like real life!).

Social Games like Castle Builder

If you’d prefer not to spend any money, there are many social options available. Castleville from Zynga is the obvious choice, and there are plenty of other dupes, including Tiny Castle and Castle Clash which are available for mobile devices.
