Release the Bison

Reviewed by Paul Clare Last updated:

There's always room for some motivated Wild symbols to add a little spice to a game and Release the Bison isn't arguing to the contrary. They roam around collecting wins and even help bring multipliers during the free spins bonus - plus there’s a chance of a random guaranteed win of up to 40x for no reason whatsoever! The max win is 3,000x and the adventure starts here.

Release the Bison Features

Pragmatic Play hasn't strayed too much from its tried and tested formula of late and that could be a good thing or a bad thing, depending on what you think of the current selection!

It's a fairly regular 5x3 set of reels with 20 paylines and some standard symbols making up the winning groups. Royal symbols max out at 1.5x for a 5-of-a-kind win made up of aces but the picture symbols are a lot more valuable. 

The wolf provides the best results from these standard paying symbols with 10x for a group of 5. As you might expect, the Bison is a little special and as a Wild symbol, it will substitute for all other regular payers. It also has a 12.5x win for a group of 5.

Wild symbols behave perfectly normally during the base game until 4 of them are present. When this happens, the Wild Respin occurs and the Wilds begin to move around the screen into different positions between each spin. Each time a new Wild arrives, wins increase by 1x. It's also possible to accumulate enough Scatter symbols here to trigger the Free Spins bonus. 

But before we head off to the promised land, there's a small feature called the Guaranteed Win. Who doesn't like the sound of that? On any losing spin, the reels may respin and convert into a win of up to 40x. 

Bonus Game & Roaming Bison

Moving on then to the free spins, you'll need 3, 4 or 5 Bonus Scatter symbols to trigger the game. The more you get, the better the results as your first job is to spin a wheel to see how many free spins you'll get and what the multiplier will be. 

  • Enter with 3 Bonus symbols and you'll get between 8 and 15 free spins and a multiplier between 1x and 5x. 
  • Entering with 4 Bonus symbols has a very similar result except the 1x multiplier is missing.
  • 5 bonus symbols produce between 10 and 18 free spins and 3x to 5x multipliers. 

Wild symbols continuously roam the reels and each new Wild will add to a meter at the top of the screen. Collect enough of them and you begin to gather more free spins and increase the multiplier potential.

Release the Bison - Wild Respin

Wild Respin

4 Wilds trigger this random feature where respins mix up the reels and WIids move to a new space between spins. You could trigger free spins here if enough Scatters fall.

Release the Bison - Free Spins

Free Spins

3–5 Bonus Scatters give you a spin on the special wheel to determine your free spins tally and an accompanying multiplier too. You could get up to 18 spins with an x5 multiplier. Wild symbols stay for the duration, roam between spins and add to the meter to bring more spins and a bigger multiplier.

Guaranteed Win

A losing spin needn’t be the end of the world! There’s a chance that a guaranteed win spin will trigger and produce a prize up to 40x.

Release the Bison Review

It doesn't really matter what the theme is, this set of features would have worked perfectly well with just about any backdrop. Wild animals are great and no one's going to complain when those wild bison start adding a little extra to the reels.

Design

We're out in the mountainside for this one and it's a lovely spring setting to get everybody in a good mood. Colourful flowers, Green grass and a gentle breeze make this an idyllic setting for some potentially big wins and you can pick up this action on mobile devices as well. The soundtrack’s perfectly inoffensive and shouldn't annoy you too much along your journey.

Gameplay

The Wild symbols are decidedly more potent when they are free to roam around the reels and this won't happen very often during the base game. That said, it can happen so don't rule it out. The Free Spins Bonus has huge potential to not only make this game more interesting but also bring far bigger wins at the same time. I saw my balance look decidedly more positive after a couple of bonus game triggers! Players outside the UK have a couple of buy-in options with a direct bonus buy for between 80x and 300x, plus a kind of golden bet offer which increases your bet by 25% to give you a higher chance of winning the bonus feature.

Win Potential

A 3,000x max win isn't going to break any records but it's still a fairly decent reward for what is quite a basic game. A good run of spins could see those multipliers build up during the bonus game and the returns may be quite interesting. Another great stat is the 96.54% RTP, which is much higher than many other modern slots. The volatility is high, so keep an eye on your balance.

My Verdict

They’ve Released the Kraken and now it’s time to Release the Bison! Unfortunately, it's not particularly innovative and we've seen all of this before from this developer and others. However, the action does arrive fairly regularly and it's possible that some big wins might stampede their way through the reels thanks to that high volatility and increasing multipliers during the bonus game.
