Verdict

Castle Builder by Microgaming isn't groundbreaking but it's well worth a spin or two. There are, as always, a few issues, such as the relatively small jackpot, however, these minor malfunctions don't overshadow the tons of positives.

The biggest is the innovative bonus feature, which sees you building a castle and collecting cash for doing so. This is certainly one of the more inventive slot machines we've ever seen online!
