Play Release the Bison Slot Game

If you’re into those online slots with roaming wilds and unpredictable twists, Release the Bison by Pragmatic Play might just catch your attention. It builds on the “Release” legacy, yes, that Kraken one, with a land-based twist, trading in the sea monsters for snorting bison. On the surface it does look different, but underneath it shares quite a bit with Release the Kraken 2. You’ll find 5 reels, roaming wilds, guaranteed base game hits, and a bonus spins round that ramps things up with a wheel-based setup. More on that below. 

The setting swaps deep-sea dread for rugged outdoors, with mountains and meadows filling in for shipwrecks and tentacles. Release the Bison definitely takes its visual cues from nature documentaries, even if the animals on the reels have slightly cartoonish expressions. The whole look is polished, if not particularly daring, and the soundscape follows suit with natural tones and quiet tension, until things kick off in bonus mode. 

The symbols are divided into card ranks and animal characters. Here's how payouts shape up: 

Special Symbols 

• Wild Symbol: The bison acts as the Wild, appearing on all reels. It substitutes for regular symbols and potentially pays up to 12.5x for five of a kind.  
• Scatter Symbol: Triggers the bonus spins. Appears only on reels 2, 3, and 4 and pays regardless of position. 

Wild Respins 

Landing four or more wilds in the base game activates this feature. All wilds become roaming wilds, shifting to new random positions between each respin. If another wild lands during the round, it too becomes a roamer, and you get another respin. The kicker? Each new wild could bump up the win multiplier by +1. Scatters collected during this mode can also trigger bonus spins if you gather three or more by the end. 

Guaranteed Win 

This one can trigger randomly after a non-winning spin in the base game. Instead of walking away with nothing, you’re potentially handed a payout worth between 10x and 40x the current bet.  

Bonus Spins 

Triggered by landing three scatter symbols or by collecting them during the Wild Respins feature, this round begins with a wheel spin. The wheel determines both the number of bonus spins and the starting multiplier. Depending on how many scatters triggered it, your setup could range from 8 to 18 bonus spins and a multiplier from x1 to x5. 

Once in, any wild that lands becomes a roaming wild for the rest of the feature. Collecting wilds adds another element: from the fifth collected wild onward, each one could grant an extra bonus spin and boost the multiplier by +1. Up to 10 roaming wilds can be collected this way. 

Release the Bison operates on a standard 5x3 reel setup with 20 fixed paylines. Wins are formed by landing three or more matching symbols on adjacent reels from left to right, starting from the leftmost reel. There are no cascading reels or megaways here, it’s just straightforward line-based play backed by wild and scatter mechanics. 

If you’re into wild mechanics and roaming reels, these other slots offer something along the same lines: 

• Buffalo Hold & Win Extreme 10,000 by Booming Games: A bison-themed slot from Booming Games with a Hold & Win bonus that plays across four unlockable grids. 
• Bison Moon Ultra Link & Win by Northern Lights Gaming: From Northern Lights Gaming, this one adds a Link & Win feature, bonus spins, and the random Bison Stampede trigger. 
• Das xBoot by NoLimit City: A grittier slot from Nolimit City with xNudge wilds, xWays reels, and aerial assault-style features. 

There’s a certain charm in how Release the Bison combines familiar mechanics with a new skin. The roaming wilds and multiplier buildup can keep things going, especially in the bonus spins round. That said, the absence of stacked wilds and reduced overall payout potential may leave some players missing Kraken's bite. Still, for a slightly toned-down follow-up with more nature and fewer tentacles, it holds its own.
