Bison Bonanza Online Slot Review

Join the stampede to the best Blueprint Gaming casinos, where you find the Bison Bonanza slot machine. Wolves, bears, and of course, bison feature on a 6x5 symbol grid and pay in any places. A cascading reels mechanism can form several wins in a sequence, and there’s a choice of free spins features with multipliers of up to 100x. These multipliers can combine to give wins of up to 10,000x your stake.

You can let the wildlife run free across PCs, iOS, Android, and Windows mobiles at our favourite casinos. There’s a medium to high level of volatility from the Bison Bonanza slot machine, matched with generous average returns of 96.5% at any of the slots uk sites.

How to Play the Bison Bonanza Slot Game

Set within the steep walls of a canyon in the American West, the reels of the Bison Bonanza slot machine are filled with playing card suits and the local wildlife. The animal symbols are reasonably realistic, although not exceptionally so, and include a bald eagle and lynx among the bears, bison, and wolves.

The card symbols add a splash of colour to the 6x5 symbol grid, and with luck you will see a golden bonus symbol glinting from the reels. The soundtrack is just what we like to hear from wildlife themed games.

You can play for between 0.20 and 10.00 per spin, which is pretty limited range that will put off a lot of potential players. Tap the Dollar symbol on the controls to reveal all staking options and you are ready to play. There’s also a Bison Bet option, which increases the stake by 25% but also doubles the chance that you trigger the free spins feature.

Before you get started though, you should check out the Bison Bonanza slot paytable, where you see how the unusual scatter pays mechanism works, and how much you win from the various symbols. Any 8 or more examples of the same symbol in view, in any places, are enough to win a prize, with the buffalo paying a maximum of 59x your bet.

Free Spins & Other Features of the Bison Bonanza Slot Machine

Winning symbols are removed from the grid and those above drop down to fill the voids left behind while new ones appear from above. If the new mix is enough to create a win this cascading reels feature repeats, with no maximum limit to how many wins you can get one after another.

Look out for the gold coin bonus symbol in any 4, 5, or 6+ places. You win an initial 3x, 5x, or 100x your bet respectively, followed by a choice of 4 free spins features with a mix of the number of games and multipliers. Here are the options –

Multiplier symbols can land at any time during the free games and if 2 or more appear over the course of any cascading reels their values combine at the end of the sequence. If at least 5 more bonus symbols appear you get an extra 5 spins, and this can potentially happen over and over again.

Bison Bonanza Slot Maximum Wins, Volatility, & Average Returns

Prizes from free spin multipliers can combine to a huge 10,000x your bet, but the low 12.50 maximum stake (with the Bison Bet active), limits the wins to 125,000.00. Blueprint Gaming rate this as a medium to high volatility game, and there’s a long-term payback percentage of 96.50%, which is very good for a slot with this level of variance.

Our Thoughts on the Bison Bonanza Slot Machine

Visually, the Bison Bonanza slot doesn’t really stand out, but it’s not bad either and the North American wildlife theme is always popular. There are some great features though, such as the unusual mechanism that pays a prize with enough symbols in any places.

Cascades and the option to pick your free games feature are some other highlights. You can grab some decent wins from enough multipliers during the free games, and the 10,000x maximum is always a possibility.

Perhaps the Mystery free spins option is the best, as you could get up to 12 spins with multipliers that can hit 500x. Explore the American wilderness as you play this exciting game at the best online casinos today.


The Bison Bonanza slot works on iPhones, iPads, Android, and Windows mobiles. Some of the controls are repositioned for ease of use, but otherwise it’s exactly the same as the desktop version.

Play the Bison Bonanza slot and you win a prize whenever 8 or more matching symbols land in any places. It’s an unusual system that effectively turns all symbols into scatters, and you can win up to 59x your bet from enough bison.

You need a minimum of 0.20 to spin the reels of the Bison Bonanza slot game. It’s aimed at lower stakes players, with a maximum bet of just 10.00 per spin, or 12.50 with a Bison Bet option that makes it easier to trigger the free spins round.

Trigger the free spins and you get 4 options. Three of these vary the number of bonus games and potential multiplier symbol values, while the fourth is the Mystery choice, which can be a combination of the other Bison Bonanza free spin options.

Symbols on the reels of the Bison Bonanza slot machine include a bear, eagle, wolf, and the bison itself. You’ll also see colourful playing card suit symbols, and a gold coin bonus emblem that unlocks the free spins.

You can win up to 10,0000x the total bet from the Bison Bonanza slot machine. However, the maximum possible stake is only 12.50, which is much lower than many other slots and limits the actual highest prize value to 125,000.00.
