The various castle-themed symbols of Castle Builder will all reveal a coin prize when lined up on adjacent reels. On a total of 5 reels and 3 rows, players get to adjust their betting amount by picking from 1 to 15 pay-lines and allotting a coin value that can range between 0.01 and 1. The Castle Builder bonus wild symbol may substitute for all other symbols except the building symbols. The building symbols are critical as they are required for the construction of the castles. There are 4 different kinds of building symbols: standard, bronze, silver and gold. The higher the quality of the building symbols, the higher the value of the completed castle. The king’s heir moves in once the castle is completed and will have to choose from one of 3 suitors. Your winnings will depend on how rich the chosen admirer is.
