Like all wild symbols, in this instance, the wild can be used to replace any other symbol to create a winning payline except for the Bonus symbol. The Wild in the Dog House is also a multiplier in contrast to other slots, with a randomly chosen value of 2x or 3x.
When more than one Wild symbol appears on a payline that pays out, they are multiplied and added to your win. Only reels 2, 3, and 4 are covered with wild symbols.
