Lunaris slot is a new type of game that Williams Interactive has introduced. Not only is the game itself filled with well designed, stunning symbols and graphics, but there are two sets of reels. This is the popular Wheel Bonus feature found in some other slot game by WMS Gaming. There is the main set of reels with five reels and four rows, and the other is a Colossal reel comprising five reels, twelve rows and therefore a total of one hundred pay lines. The interaction between the two sets is something that makes this game unique.
