The bison is one of the mightiest animals in nature, and his might has been the focus of many myths and stories. This unstoppable force of nature has stomped its way into the slot industry, too. Nailed It! Games and Games Global have teamed up to release a slot based on the mighty animal in the Unstoppable Bison slot.
The story – and what you might expect in the slot – are kind of obvious. Most animal- and especially bison-themed slots stick to jackpots and a hold-and-win-like bonus round. The Unstoppable Bison adds a few tweaks, but generally, it doesn’t stray too far from the usual path.
This isn’t a bad thing at all. The slot’s still fun to play, even if it’s a bit too familiar. There are still big prizes to be won thanks to the features, and the fact that the game uses a standard math model with 40 paylines will appeal to fans of regular slot games. Read my detailed Unstoppable Bison review and try the demo mode.
Unstoppable Bison has a lot going on when you fire it up. The 5x4 layout is in the middle of the screen, pressed against North American mountain peaks on one side and a canyon on the other. You’ll see a spinning jackpot wheel to the right, while the left is reserved for the jackpots and the bison looking over the action from the top.
Symbols include wild animals, including the bison, an American eagle, a lynx, a stag, and card royals. They’re complemented by a wild and a scatter. The slot’s paytable and guide are easily accessible using the control grid beneath the reels.
The Americana soundtrack in the background makes everything even more fitting. Overall, the studio has nailed down the whole package when it comes to visuals and audio.
In general, the slot doesn’t bring anything new to the genre, nor does it pay record-breaking rewards.
Set a bet to start playing the Unstoppable Bison online slot. You can choose between 20c and $40 per spin. Check out the settings if you want to play without music or in turbo mode, then hit the blue spin button to get started.
The Unstoppable Bison slot works just like you would expect it. You need three or more matching symbols on a line for a win. Canyon wilds can step in and substitute for other symbols in winning combinations. Naturally, the bison pays the most out of all the premiums.
Bison symbols with a star overlay can land in the base game. They’re collected in the wheel, and each one of these stars may trigger the jackpot wheel bonus game. It’s available in all stages, and when triggered, it gives you a single spin to win one of the available jackpots.
The jackpot wheel features several segments with smaller prizes and only one for the Grand jackpot. You can win the following:
Land a stack of bison symbols to trigger the respins. All bison symbols will then move to the left and award a single respin. If a new bison symbol lands during the respin, you get another one. All bison symbols stay sticky for the duration of the respins feature, and there’s no cap on the amount of respins you can win.
The free spins round triggers with three or more scatters. You receive five, six, or seven scatters depending on the number of triggering bonus symbols. Only bison symbols are in play during the bonus, which plays similarly to the respins.
Buying the bonus round is a no-go, so you must wait and trigger it naturally.
I started my journey through the wilderness with a bet of $1. The Unstoppable Bison slot was a fun experience, although I must confess that I’ve seen it all before. I couldn’t hit wins over 8x during my first 20 spins, even with the respins, which triggered often. Although the game generally gives plenty of chances to win with the sticky bison and a shot at the jackpot wheel, I wasn’t very successful.
It took around 60 spins to reach the bonus round, which wasn’t particularly impressive. That’s mainly because I won just five free spins, which weren’t enough for bigger wins. Ultimately, I left the free spins round with only 14x in wins.
Unstoppable Bison has a medium volatile math model with an RTP of 96.14%. The maximum payout is tied to the Mega jackpot and pays 5,000x the bet.
Unstoppable Bison is a slot that appeals to fans of animal-themed and nature-themed slots. It doesn’t explicitly state there’s a Hold & Win bonus round, but the respins and even free spins work in a very similar way. The jackpots are a nice addition, and the fact you can trigger the jackpot bonus anytime should sit well with most players. However, in general, the slot doesn’t bring anything new to the genre, nor does it pay record-breaking rewards.
If you’re looking for alternative bison or buffalo-themed slots, you’ll be glad to know there are many you can try at the top casinos online. Games Global’s Blazing Bison Gold Blitz is a good jackpot game, while Blueprint Gaming’s Bison Rising Megaways offers a Megaways take on the bison theme.
