The beehive is the wild symbol and it will substitute for all of the other symbols, except for the scatter and bonus symbols, to help and form more winning combinations.
The wolf is the scatter symbol and the moon is the bonus symbol.
The slot features Swooping Reels. This means that whenever a winning combination lands on the reels, the symbols in the combo are blown away to allow more to fall from above. With a bit of luck, this will form another win and the feature will then repeat itself. Better yet, the more wins you form from the Swooping Reels, the further along the Pigs Turn Wild feature you progress.
Above the top right of the reels you can see the three pigs, each one with two circles beneath it. Each Swooping Reels win fills in one of these circles. When two circles are filled, the first pig becomes wild, when four circles are filled, the second pig becomes wild and when six circles are filled the third pig becomes wild.
Landing three or more of the wolf scatter symbol on the reels triggers the free spins. The game begins with a short video of the wolf blowing down the house and then the spins start. During the spins, if you land three moon bonus symbols then the wolf blows down the wooden house and awards you two more spins. The game then progresses to the brick house and landing six moon symbols results in this house being blown down and two more spins plus a x2 multiplier being awarded.
There is a top payout of 1000x for landing five wild symbols along a payline. The pig with a candy cane can payout up to 300x, the pig with a gingerbread can payout up to 250x, the pig with a spoon can payout up to 250x, and the stuffed toy can payout up to 200x. A, K and Q can all payout up to 100x while J and 10 can both payout up to 75x.
