Bison Bonanza Slot RTP, Details and Wager Limits
The Bison Bonanza slot is played on a 6×5 grid and uses a Scatter Pays mechanic. To land a winning combination, you need 8 or ore matching symbols anywhere in view. It works differently to grid slots where you need matching symbols appearing adjacent to one another. The way pays are awarded is identical to that seen in Pragmatic Play’s Sweet Bonanza.
Bet options range from 20p to £10 a spin. Click on the ‘Dollar Bill’ icon which brings up all available stakes on a separate page. Outside the UK, you will find an Autoplay function (located below the main ‘Spin’ button) which allows up to 100 autospins with session loss and single win limits.
The Bison Bonanza RTP is 96.5% which is much higher than the 96% industry average. The RTP increases further with the Bonus Buy feature (more details below). In terms of volatility, it’s in the medium to high category (4/5).
When it comes to payouts, the maximum win from a single spin is 10,000 x your total stake. The bigger wins will come during the free spins where the multipliers can reach 500x.
Theme – roam the reels with the almighty bison
With a Native American theme, the Bison Bonanza slot is based on the American bison. Set in a canyon, the soundtrack is upbeat and triumphant. It has the look of a land based slot or a little like Playtech’s Buffalo Blitz. If you’re a fan of Blueprint Gaming slots, you will see the similarities with games like Wolf Legend Megaways for example.
On the reels you will see spade, diamond, heart and club royals. Then you have higher value lynxes, wolves, eagles, bears and American bison. The American bison symbol is the best paying with 12 or more awarding you with 50 x your total stake.
The gold bison coin is the scatter symbol with 4 in view triggering the free spins (more details below). There is no traditional wild symbol.
| Symbol | Payouts/Info |
|---|---|
 Club | 12+ pays 2 x stake |
 Diamond | 12+ pays 4 x stake |
 Heart | 12+ pays 5 x stake |
 Spade | 12+ pays 8 x stake |
 Lynx | 12+ pays 10 x stake |
 Wolf | 12+ pays 12 x stake |
 Eagle | 12+ pays 15 x stake |
 Bear | 12+ pays 25 x stake |
 American Bison | 12+ pays 59 x stake |

Bison Bonanza Mobile
Producing using HTML5 technology, Bison Bonanza is available to play on mobile, tablet, laptop and PC devices. This encompasses iOS, Android, Windows and/or MAC operating systems. The 6×5 layout works well on smaller handheld devices too.
Bison Bonanza Bonus Features
The Bison Bonanza slot comes with 4 bonus features. With cascading wins, it’s all about the free spins where you choose your free spins and win multiplier range. A set of cascades during the feature will be subject to the total of multipliers in view. You also a Bison Bet option which doubles your chances of playing the free spins.
Cascades feature
When you form a winning combination, the Cascades feature is triggered. Winning symbols are removed from the reels with the remaining symbols dropping down into the empty positions. New symbols then fall in from above giving you another chance to land a win. The cascades continue until no more new wins are created.
Free Spins feature
The Free Spins feature is activated when 4 or more gold bison coin scatters land anywhere in view. You then have a choice of 4 free spins options. You can play with more free spins with smaller multipliers or less free spins with multipliers up to 500x. There’s also a Mystery option where any combination of free spins and minimum multiplier will apply. Here are your options:
| Option | Free Spins | Multipliers |
| 1 | 12 | 2x up to 100x |
| 2 | 8 | 4x up to 200x |
| 3 | 5 | 8x up to 500x |
| Mystery | 5-12 | 2x up to 500x |
If any multipliers land during any winning cascades, the final win from all cascades will be subject to that multiplier. If there are multiple multipliers, these are totalled and applied. Landing 3 or more scatters will result in 5 additional free spins. There’s no limit to the number of free spins you can play with.
Finally, you have the Bison Bet feature. For a 25% increase in your bet/stake, you double your chances of triggering the Free Spins feature. At minimum stakes for example, it will cost you 25p per spin.
Bonus Buy feature
Outside the UK, players can opt for the Bonus Buy feature. This allows you to jump straight into the free spins with a couple of options. Costing at least 100 x bet, there’s also a Bison Wheel. The RTP also increases when these options are exercised:
| Option | Details | RTP % |
| Free Spins feature entry | Up to 12 free spins + 500x multipliers | 96.6% |
| Bison Wheel | 10-20 free spins + any combination of multipliers | 96.82% |
Bison Bonanza Review Summary – scatter pays + multipliers in free spins can lead to stampeding wins
Visually, the Bison Bonanza slot resembles other Blueprint Gaming titles such as Buffalo Rising Megaways. The gameplay is relatively simple but the scatter pays mechanic and cascades can lead to decent wins in the base game.
The main action will come from the Free Spins feature. I would personally opt for the higher win multipliers as these can lead to huge payouts of up to 10,000 x your total stake. There’s opportunities to win additional free spins which helps with the 5 free spins offered if you go for the high multiplier option.
The gameplay is very similar to that of Sweet Bonanza but the multipliers on Bison Bonanza are potentially higher. That said, the max win of 10,000 x bet is less than half offered in Pragmatic Play’s flagship game (21,175 x bet max win). Most Blueprint Gaming slots lately offer 50,000 x bet max wins so this feels a little underwhelming truth be told.
In summary, Bison Bonanza is a decent slot which focuses on the multipliers in the free spins. It also offers a high 96.5% base RTP rate. If you like the theme, Nolimit City’s Buffalo Hunter and Push Gaming’s Bison Battle are great slots with bigger potential wins (12,647 and 50,000 x stake wins).
