The online version at Betfair is identical to the land-based game, and for the month of May, Wolf Run is Betfair’s Game of the Month.
You can play on either desktop or mobile, and if you wager at least $50 on Wolf Run this month, you get $5 back for the promotion.
The Wolf silhouette in front of a full moon is a wild symbol, and the “stacked wilds” appear in groups on the reels. Since you often have multiple wild symbols visible at once, you often have payoffs on many lines at the same time.
The bonus round is triggered by getting three scattered Bonus symbols. (Note that Wilds can’t substitute for a Bonus symbol.) The Bonus symbols appear only on the 2nd, 3rd, and 4th reels, but they do not need to be lined up on a payline to trigger the bonus. The feature immediately awards 2 times your initial bet, and then awards 5 free spins at the original bet size.
If you hit three Bonus symbols during your free spins, you are awarded an additional 5 free spins. In my experience, the Bonus symbols seem more frequent during the free spins making re-triggers happen more often than you might think.
For the month of May, play $50 or more on Wolf Run at Betfair and get an extra promotional $5.
