Unstoppable Bison slot

Theme and graphics

If you read the title of this game, it gives the idea that the slot surrounds animals, or at least the bison. That much is true, and there are other animal symbols included on its reels, too. Yet the theme expresses so much more once you start playing Unstoppable Bison. The background depicts the North American wild, situated within the midst of the Rockies. Clouds drift by the vast mountains at either side of the reels, while sparse desert vegetation, including cacti and shrubs, occupy the land.

The graphics come from the Games Global subsidiary known as Nailed It! Games, are sublime, transporting you right into that scene. Sparks and embers appear to drift up from the bottom of the game screen, too, adding extra heat to the design. There is also an almost country-sounding piece of music playing while you spin the slot’s reels. This lightens the tone a little but combines well with the theme. Speaking of which, that theme explodes to life when you see the bald eagle, the stag and the other animal symbols on the reels.

You can always try the game for free on demo mode if you’re unsure of the theme of the game mechanics. This will let you experience the game in full without spending any real money.

Gameplay and features

You’ve got five reels to spin in the Unstoppable Bison slot machine, which is common for many video slots. Four rows are present alongside those reels, presenting a good size gaming layout. Nailed It! has also added a set of 40 paylines to the slot, which runs from left to right, and are not customisable.

Line wins in the slot start on reel one and then proceed to the right; otherwise, they don’t count. Only the highest win per payline is awarded, and a paying combination needs to feature at least three matching symbols.

Alongside the animal symbols of Unstoppable Bison – the stag, the ocelot, the eagle and the bison – there are lower-paying playing card symbols involved, too. They run from J to A, offering payouts of up to 1x your stake. That’s not all, because there is a wild symbol to benefit from as you spin the reels.

Symbol	Name	Function
	Wild Symbol	Substitutes for all other basic symbols, helping you to create winning combinations across the reels. The only exception to the substitution rule is the free spins symbol.
	Free Spins Symbol	Triggers the game’s free spins round when three or more land anywhere. Up to 7 free spins can be won.
	Bison Symbol	Top paying symbol with special features attached to it. This includes respins when a stack lands and the triggering of the bonus game.

During the base game of Unstoppable Bison, payouts hit at average intervals. This has a lot to do with the game’s medium volatility level. Of course, you still need to place responsible bets to cater to periods when you may experience multiple consecutive losing spins.

Bonus rounds and free spins

I have mentioned the bison symbol in this slot review, and if it lands in a stack on any reel, it triggers the Respin Feature. All bison symbols will move to the leftmost position in this case, and a single respin is provided. Each spin that lands a bison symbol guarantees another respin. Bison symbols are sticky throughout the feature.

You may also see bison symbols with a star symbol attached. Stars are collected in the jackpot wheel on the right of the reels. Each star can randomly trigger the bonus game, giving you the chance to win one of four jackpots. They are always displayed to the left of the reels. Simply spin the wheel and win up to 5,000x your stake.

Don’t forget about free spins, either. It takes three or more of the gold coin bison symbols to land anywhere to activate this round. You’ll receive between 5 and 7 free spins, depending upon the number of triggering symbols. Only bison symbols appear on the reels during the round, moving to the leftmost position in their row and remaining sticky throughout.

Of all the special features included in Unstoppable Bison, the respins feature is the one that hit the most in my experience. The round didn’t go on for any longer than one respin, though. It’s nice to see the stars being collected in the jackpot wheel, although many were collected during my time playing it, and I never got to experience the bonus game. It’s likely that the game is one for those players who have plenty of patience.

Payout potential and volatility

The maximum payout available in this online slot is 5,000x your stake. This exists as the general average maximum for video slots, which suits it well. You’re able to achieve this by experiencing the bonus game, which features the Mega jackpot of such an amount.

Keep in mind that Unstoppable Bison is a medium volatility slot, too. This means that wins will hit at fairly frequent intervals and will provide payouts of an average amount. As a result, the game will appeal to high and low rollers, although if you’re someone who likes bonus features, Unstoppable Bison caters much more to players who have extensive bankrolls.

Something else to take note of with the game is that it features a 96.14% RTP rate. That’s above the 96% average, which is great. If you’re not familiar with this detail, RTP stands for return to player. It dictates the amount you can expect to receive back as an online slot player. The percentage is something that is worked out across thousands of spins on a game, though. So, in the long-run, you can expect to win 96.14% of your bets back.

Here is how Unstoppable Bison stacks up against some other recent releases from this brand in terms of RTP and volatility.

Game	Volatility	RTP	Max Win
Unstoppable Bison	Medium	96.14%	5,000x
Riptide Fishing	High	96.14%	5,000x
Explosive Gold Blitz	High	96%	5,000x
Raging Gods: Olympus	Medium	96.09%	5,000x

Evidently, there has been a focus on providing slots with a maximum payout of 5,000x the stake from Nailed It! Games and Games Global lately. The RTP rates in the recent releases don’t differ on a dramatic level, all being of an average level and above, which is excellent. Unstoppable Bison is one of the less volatile options to play of late, though.

Playing Unstoppable Bison on mobile

You can also play Unstoppable Bison via a mobile device if you like. It is compatible with Android and iOS devices, so it is readily accessible on smartphones and tablets. This way, you can enjoy its gameplay and features at any time. One point to make about this form of play is that it can occur vertically or horizontally. However, what I found was that when I turned the screen horizontally, the game was cut off a lot at the top and bottom. It was still playable, but it made changing the bet difficult. Otherwise, the layout of the game remains the same, other than the jackpot wheel being at the top of the reels and the buttons for gameplay at the bottom. It provides a high-quality slot with stunning graphics and animations, with the game itself being responsive to touchscreen capabilities.

Final verdict on Unstoppable Bison game

Unstoppable Bison by Games Global has a lot to offer to online casino players. Its stunning graphics lead the way, while the betting range, RTP rate and inbuilt features add to its overall appeal. It’s a shame that the mobile version of the game has a couple of issues and that the bonus game/free spins don’t hit more often. Even so, it’s a slot that holds plenty of its own appeal if you play responsibly and enjoy the theme to the max.
