The imagery in Wolfpack Pays is impressive - a riverside scene forms the backdrop to the reels which include hearts, diamonds, clubs and spades alongside an eagle and howling wolf silhouette. The wolf is the game's wild - it can appear as a stacked symbol to fill an entire reel and substitutes for all other symbols.
You'll notice that there aren't any scatters on view - you may worry in fact that there aren't any free spins on offer. Fear not though, they're just triggered in a slightly unorthodox manner using the On A Roll feature. After any winning combination hits, you'll be awarded a free spin.
Wolf wilds are added at the start of each free spin - after 1 win, the wild will appear on reel 3. After 2 winning spins, they appear on reels 2, 3 and 4. After a third win, they can hit on all 5 reels. You can keep track of how many successive wins you've had via the meter in the top right hand corner of the screen.
If you're lucky enough to manage 4 consecutive winning spins, you'll trigger the Wolfpack feature and be awarded even more free spins, this time with an extra 5 wild wolf symbols added to the reels. You'll start the Free Games feature with 3 paw prints in the bank - after every losing spin, you will lose 1 of these paw prints. The free spins keep on coming until you run out of paw prints.
Wolfpack Pays offers plenty of action and a steady stream of smaller wins - there are chances to win big but you really need to get on a winning roll and land the extra added wilds in a decent formation.
That said, there's plenty to enjoy here - the sound and visuals are well done and the On A Roll re-spins are a nice variation on a traditional feature. Get the winning spins flowing here and this wolf pack can get you howling with delight. If you like the theme, there are plenty of wolf-inspired games with IGT’s Wolf Run and Quickspin’s Big Bad Wolf the better ones.
