Rainbow King Bonus Features

Rainbow King Feature 
Three or more King icons trigger the Rainbow King Feature. Here, you move a character over the game board by throwing dice, and can pocket different winnings on each square. When your game character lands on a Rainbow King square, a small slot game is activated which you can play when your game character lands on a "Take the Money" square.

More winnings await you at the small slot games, at least provided the "7" appears on your three reels!
