The wild icon in the Castle Builder slot is the old man. This symbol will reward players with a substitute feature when it appears. It can replace all icons, save for the building symbols. There are four of those (standard, bronze, silver and gold). The player needs these icons to start building a castle. When the castle is complete, the player must choose from three admirers. The decision you make will determine your pay-outs in this Royal Wedding bonus.
