Wolf Run is an IGT slot machine that has been popular in American casinos for many years, and the online version followed in 2014. The demo on this page is that standard game, with 5 reels, 4 rows and 40 paylines. You can play it here for free on play-money credits.
It is a straightforward game with two things to watch. The howling wolf is a wild symbol that lands in stacks and can cover whole reels. Bonus symbols on the three middle reels start a short free spins round that can be won again while it plays. There are no side games or jackpots.

How Wolf Run Works
The reels are 5 columns by 4 rows with 40 paylines. A payline is a fixed path across the reels, and wins pay from left to right starting at reel 1. With all 40 lines active, the smallest bet is 0.40 credits per spin. The top bet varies from one casino to another.
Wolves are the main picture symbols. The howling wolf is the wild. It replaces the regular symbols to complete a line, and it is stacked, meaning it often lands two or more high on a reel. Other symbols can stack as well, so matching reels side by side can pay on many lines at once.
The RTP is 94.98%, a little below the average for online slots. RTP is the share of all bets paid back over a very long time. Volatility is rated low to medium. That points to frequent small wins and a balance that moves slowly, with fewer large payouts than a high-volatility game.
Wolf Run Bonus Features
Stacked Wilds
The howling wolf wild appears in stacks of two or more on the reels. A full stack turns a whole reel wild, and wild reels next to matching symbols can complete many of the 40 lines in a single spin.
Free Spins Bonus
Three Bonus symbols on the center three reels, which are reels 2, 3 and 4, pay 2 times your bet and award 5 free spins. The spins are played at the bet of the triggering spin.
Retriggers
If three Bonus symbols land on the middle reels again during the free spins, the bonus is retriggered and more free spins are added. A round that starts with 5 spins can therefore run a good deal longer.
More Wolf Run Versions to Play Free
Wolf Run Eclipse is a newer 20-line game with high volatility, bonus wheels and four fixed jackpots. Wolf Run Wild Moon keeps the stacked wilds and adds wilds that nudge to fill a reel, jackpot prizes and a free games feature. Fort Knox Wolf Run adds IGT’s Fort Knox bonus, which has fixed jackpot tiers and a shared progressive. Wolf Run MegaJackpots links the game to a progressive jackpot. All four have different RTP settings from the original.
Good to Know Before You Play
- Five free spins is a small award. The round’s value comes from retriggers and from stacked wilds landing during the spins.
- Bonus symbols only count on reels 2, 3 and 4, and you need one on each of those reels in the same spin.
- The 94.98% RTP is lower than many newer online slots. In free play this only affects how long your credits last.
- Sources disagree on the top prize, so we have not listed one. The pay table in the demo shows every line prize.
