Castle Builder

Medieval 5 Reels 15 Paylines Low Volatility


Build castles, host weddings and progress though levels to strike it rich in Castle Builder.

Castle Builder is a 2014 release from Odobo which is based on the Austrian lottery's game, which goes by the same title. 

It must have been a challenging game to create, but Odobo have once again nailed it, featuring multiple levels and a beautiful narrative to a traditional medieval-themed 5-reel video slot.

You begin the slot in the Kingdom of Forana where you are lucky enough to be entrusted with building a royal castle for the King's daughter.

Castle Builder is a great slot in that you aren't just mindlessly spinning - you are actually progressing, and building! There are 15 paylines to the slot but it plays out with low volatility as the wins are small and often. There are wilds, just like other slots, which can trigger winning paylines, but you are probably more interested in the 'building pay symbols', which come in different colours and need to fall on winning paylines in order for you to construct.

Admirers will soon be knocking on the door, and once construction has finished, it is time for the Royal Wedding Bonus. The marriage takes place, and depending on how rich the suitor is, you win a proportional amount! 

This is a brilliant slot that keeps you hooked with the frequent wins, which does mean you can follow the progress of your castle. The level-up bonuses are very generous, but Castle Builder just doesn't seem to be able to provide the really big, landmark wins. Despite the bonus features, we'd class this as a low volatility slot.
