Release the Bison Slot RTP, Details & Wager Limits
Release the Bison is played using a 5-reel, 4 row machine that’s made up of 20 paylines. Land 3, 4 or 5 matching symbols or wilds from left to right in a payline, starting from the leftmost reel to create a winning combination. It’s a simple, classic setup.
There’s something to suit all bankrolls when it comes to bet levels. Stakes start at 20p rising to a maximum of £240 per spin. Click on the + and – tabs next to the spin button to adjust your bet size.
If you’re playing in a territory that allows autoplay, you can set between 10 and 1,000 autospins. There are also quick and turbo spin modes available. These aren’t available to players in the UK.
In most cases, the Release the Bison RTP is 96.54% which is better than the average figure seen at UK casino sites.. There’s also a version with a 95.48% return to player rate edition so try and find the one with the higher number.
One thing both versions have in common is extremely high volatility. This is 5 out of 5 on the variance scale so tread carefully. The hit rate is 1 in 3.45.
The most you can potentially win from a single spin here is 3,000 x bet. The max win probability is 1 in 16,129,000.
Theme: aesthetically appealing
There’s a cartoonish quality to the design in Release the Bison slot game, which is very easy on the eye. Set against a backdrop of snow-capped mountains and lush green fields, the reels are situated within a wooden frame. The colourful visuals here are terrific, backed by a jaunty soundtrack which is a good fit for this rather light-hearted theme.
There you’ll find A to 10 royals and four higher value animal symbols. The best of the standard symbol is the wolf which pays 10x bet if you land 5 in a line.
The bison is the wild. This substitutes for all the standard symbols when it makes up part of a winner. Finally, there’s the diamond which is the game’s scatter symbol. Land 3 or more of these to trigger the feature round.
Here’s what the symbols award:
| Symbol | Payouts/Info |
|---|---|
 10 | 3, 4 or 5 = 0.15, 0.25 or 0.5 x stake |
 J | 3, 4 or 5 = 0.2, 0.3 or 0.6 x stake |
 Q | 3, 4 or 5 = 0.25, 0.4 or 0.7 x stake |
 K | 3, 4 or 5 = 0.3, 0.5 or 1 x stake |
 A | 3, 4 or 5 = 0.4, 0.6 or 1.5 x stake |
 Cat | 3, 4 or 5 = 0.5, 0.75 or 2 x stake |
 Hyena | 3, 4 or 5 = 1, 1.5 or 3 x stake |
 Eagle | 3, 4 or 5 = 1.5, 2 or 4 x stake |
 Wolf | 2, 3, 4 or 5 = 0.5, 2, 3 or 10 x stake |
 Wild | Substitutes for all + pays 0.5, 2.5, 5 or 12.5 x stake |
 Bonus Scatter | 3+ triggers Free Spins feature |
Release the Bison Mobile
Pragmatic Play has created a fully optimised Release the Bison mobile slot which is available to play on iOS, Android and Windows devices. The smartphone and tablet versions play really smoothly, combining classy sound and visuals with simple but explosive gameplay.
Release the Bison Bonus Features
This wild adventure comes with a good range of extras. Bonus highlights include wild re-spins and free spins with multipliers. You could even benefit from a randomly triggered guaranteed win. We’ll start with the wild re-spins.
Guaranteed Win feature
This can trigger at random on any winless base game spin. The losing combination transforms into a winner and you’ll receive a bonus prize of between 10 x and 40 x bet.
Wild Re-Spin feature
Land 4 or more wild symbols on the same spin and you’ll receive a re-spin. On that re-spin, the triggering wilds roam to a new position on the reels. If a new wild symbol lands on the re-spin, the process is repeated and another re-spin follows. The re-spins continue until there’s one where no new wild lands. If a scatter symbol lands during the Wild Re-spin Feature it’s collected.
Free Spins feature
Land 3, 4 or 5 scatter symbols on the same spin (or collect them during the Re-Spin Feature) and you’ll trigger the Free Spins feature. Land 2 scatters and you could randomly receive an all-important third. Before the round starts, you’ll spin a bonus wheel. This determines how many free spins you’ll receive and what multiplier you’ll begin with. The numbers vary depending on how many scatters triggered the round.
- 3 scatters = 8, 10, 12, 15 or 18 free spins with a 1x, 2x, 3x, 4x or 5x multiplier
- 4 scatters = 8, 10, 12, 15 or 18 free spins with a 2x, 3x, 4x or 5x multiplier
- 5 scatters = 10, 12, 15 or 18 free spins with a 3x, 4x or 5x multiplier
Land a wild during this feature and it transforms into a roaming wild which moves to a new position on the reels with each spin. Each wild that lands is also collected in a meter above the reels.
After you have collected five wilds, 1 extra free spin is awarded and the value of the multiplier rises by 1x. One extra spin and a 1x multiplier boost are applied with each subsequent wild that appears. It’s possible to collect up to 10 wilds which means five extra spins as well as a big multiplier boost.
Ante Bet feature
In some jurisdictions, you can increase your chances of triggering the Free Spins by activating the ante bet. This takes your standard bet from 20x up to 25x per spin. For example, a £1 bet becomes £1.25.
Buy feature
There are also options to buy the feature.
- Trigger with 3 scatters = 80 x bet
- Trigger with 4 scatters = 150 x bet
- Trigger with 5 scatters = 300 x bet
Neither the Ante Bet nor the Buy the Feature options are available to players in the UK.
Release the Bison Slot Verdict: Not as good as the Kraken series
We enjoyed this virtual trip to the American wilderness. Visually, it’s excellent and the soundtrack fits the theme perfectly. Pragmatic Play has packed in a solid range of extras here too. The Wild Re-spins and Free Spins can both deliver some top action if the roaming wilds and multipliers work their magic.
Be warned tough, this wild adventure is an extremely volatile one. The maximum win of 3,000 x bet isn’t the highest you’ll find but the return to player rate of 96.56% stacks up well.
Combine the impressive design with the varied gameplay and in Release the Bison you have a very playable slot. However, when you compare it to the likes of Release the Kraken 2, it just falls short in comparison for me. Check out our free demo and give it a try.
