Castle Builder is an innovative, 5-reel and 15 pay line online slot game powered by Microgaming. In this game you’ll find yourself on a quest to build castles for beautiful princesses to move into, and your progress will be level-based. For each level, a King will ask you to build a castle for one of his daughters, and once completed, there will be a royal wedding. The game features a map to detail your progress so far; i.e. castles that have been completed, and the reels take up quite a small proportion of the screen as the progress of the castle is displayed on the left side.

The Castle Builder reels feature symbols relating to the story line. There is a Prince, Princess, Queen and King, plus a money pouch, a jewellery box, a treasure chest and a padlocked door. There is also the Wild symbol, represented by the assigned architect to construct the castles under your instructions. The wild symbol substitutes all symbols within the game except for Building symbols.

Building symbols are the vital symbols within the game; as without these the player is unable to level up. There are 4 types: standard, bronze, silver and gold. At least two building symbols must land on active pay lines, from left to right, in order to continue with the construction of the current castle. Two landed symbols award the standard type, while 3, 4 and 5 award bronze, silver and gold respectively.  The quality of your finished castle will depend on the type of building symbols you have collected, i.e. collecting lots of gold building symbols will build you an extremely high quality castle.

Once the construction of a castle has been completed, the King’s heir must choose from 3 admirers before moving in. One of these admirers will be poor, one average and one wealthy. It isn’t until after the selection is made that the player finds out which is which, and wins a sum of money based on the choice….so let’s hope you make the right one! There is then a Royal Wedding, before you advance to the next level and attempt to complete another castle.

Verdict

Castle Builder is an unusual slot game which doesn’t feature free spins or bonus games, but instead a level-based story line in which the aim of the game is to build castles. The concept works effectively and ultimately, Microgaming have produced a really enjoyable, engaging and entertaining game. The construction of each castle doesn’t take long, and I discovered that I wanted to keep going and build more. This is a truly innovative slot game and something that I would love to see more of from Microgaming (and other producers) in future.
