The slot is based on five reels and four rows with forty paylines. Winning combinations are paid out from left to right, beginning with the first reel. All winning combinations need a minimum of three identical icons on a payline except for the upper paying bison icon, which needs at least two. Although the bison symbol is not unique to this game as it is used in many Buffalo-themed slots, it plays a significant role in the slot's resspin mechanism.
In addition to playing in the base game, players can also enter free spins and other bonus features. As such, Unstoppable Bison offers a much more interactive experience compared to some of its predecessor Slots.
When a full vertical column of bison icons appears on the reels, the Bison Respins feature is activated. The bison icons remain locked in position and each remaining reel respins. Each new set of bison icons added remains locked in place as well, continuing the respin process. The respin sequence ends when no new bison icons appear or when the entire grid is filled.
This mechanic is effective because it provides visual progress. Players can watch the bison icons being placed on the reels and moved towards the edge of the reels. The respin process is also fun due to its rhythmic nature. The first group of bison icons creates excitement. The second group builds pressure. The third group turns the entire spin into potentially exciting opportunity. For many players, the respin mechanic will be the best aspect of the base game.

The Sticky Bison feature extends the Bison Respins feature by allowing bison icons that appear on the reels to become sticky and remain in place for subsequent spins. This increases the chances of forming winning combinations and enhances the overall excitement of spinning the reels.
The Star Collection System adds a long-term element to gameplay. Occasionally, bison icons will contain a star. When these stars are collected, they are added to a "pot" or "meter" associated with the Bonus Wheel. Collecting a predetermined number of stars will increase the probability of activating the wheel. One interesting note is that the Star Collection system can track stars separately by bet size. So, for example, if you switch to a higher stake size, your Star Collection may reset.
The Star Collection System provides a sense of progression between big feature triggers. Even if a spin does not generate large winnings, collecting stars can give players a sense that they are accumulating stars leading up to the wheel.
Once activated, the Bonus Wheel can award one of several fixed jackpot prizes. Unlike progressive jackpots, these jackpot amounts are static and tied directly to player bets. However, since progressive jackpots typically contribute little to RTP for players, this fixed jackpot structure allows for more predictable outcomes. Many players prefer slots with fixed jackpots over those with progressive jackpots.
Players can expect smaller jackpots to occur more often than larger ones, providing a fair expectation for what type of payout to anticipate. While the maximum possible jackpot is 5,000x (the largest jackpot), most times players will receive significantly smaller awards. Overall, the fixed jackpot structure provides an attractive alternative for players looking for a more consistent experience.
Three or more scatter icons on the reels will trigger the Free Spins feature. During this feature, any bison icon that appears on the reels will move to the left and become sticky for the duration of the feature. This encourages players to try to fill the screen with sticky bison icons, creating large winning opportunities.
While free spins can initially seem uneventful until many sticky bison icons have accumulated on the reels, once they start accumulating, the final spins can become very exciting. The difference between free spins and bison respins lies within their design philosophies. Bison respins are an optional event that occurs randomly during normal gameplay. Free spins are more deliberate and allow players to pursue a goal – in this case, trying to achieve a completely sticky bison-covered screen. Bison respins are spontaneous. Free spins are purposeful. Both mechanics produce successful results; however, free spins tend to lead to greater payouts due to the increased number of opportunities for sticky bison icons to accumulate.
Unstoppable Bison has an RTP of 96.14%, making it slightly higher than average among today's slots. Volatility-wise, Unstoppable Bison is classified as medium-volatility. Due to this classification, Unstoppable Bison will likely provide a more even session flow when compared to high-volatility bison slots. High-volatility slots often result in extremely long dry-spell periods where few wins occur, resulting in frustratingly long gaming sessions.
Therefore, Unstoppable Bison was designed to provide a much smoother gaming session flow by limiting excessive dry spells and instead encouraging players to participate in various bonus events and respins.
RTP stands for Return To Player and represents how much money players should theoretically recieve back after placing a series of wagers based upon how much money is returned as winnings against total bets made. Volatility measures how frequently and large wins occur relative to losses. In general, high-volatility slots have infrequent large payouts while low-volatility slots have more frequent but generally smaller payouts.
With an RTP of 96.14% and medium volatility, Unstoppable Bison is neither extremely low-risk nor extremely high-risk. It sits somewhere in-between. The hit frequency of approximately 23.65% ensures that wins occur relatively consistently but may not always result in large payouts. This makes Unstoppable Bison appealing to players who want to avoid extreme volatility but still want to experience occasional large payouts. Players will benefit from having a good idea of their expected returns prior to launching their preferred stakes. Launching your desired stakes immediately will help maximize your session length and ensure you spend more time enjoying Unstoppable Bison rather than waiting for potential wins.
This game offers an excellent chance to win as much as 5,000x your total bet. That is a reasonable amount for a mid-volatility game. Players looking to take a shot at 20,000x or 50,000x wins will likely find this small compared to other games. While the grand jackpot is the most obvious way to reach the highest possible payout, free spin rounds and additional bison respins offer large payouts. However, since the fixed jackpot wheel is clearly the largest single win available, casual players will be satisfied with 5,000x; while extreme volatility players will probably view this as too low.
A demo version of Unstoppable Bison is very helpful, particularly due to the fact that seeing these features in action can greatly enhance understanding. To illustrate this, reading about sticky bison symbols is vastly different from watching bison stack symbols move left, stick into position and cause more respins. Additionally, the demo allows you to experiment with the game's speed. Some players will love the steady flow offered through medium volatility. Other players may prefer a more aggressive bison slot machine offering greater winning opportunities. If you intend to wager with real cash and have decided to try the demo, you'll get an idea whether the bonus round timing and overall gaming style suits your preferences.
Due to its development via HTML5, the Unstoppable Bison mobile edition runs smoothly across all mobile devices. The 5 x 4 grid layout is easily viewed on mobile devices and the sticky bison mechanism is just as easy to follow. The Bonus Wheel also functions well with touch screen control. Turbo settings and autoplay options are generally available. Depending on local regulations and/or the casino, some may limit access to certain options. In general, Android users, iPhone users and tablet users will experience a similar experience to playing on their computer.
While no tactic can affect a random slot outcome, strategic management of sessions can certainly add enjoyment to the game. First, you should always maintain a consistent betting level when tracking star collection individually based on each bet. Maintaining a single comfortable betting level can help you keep better track of how far along you are in completing the bonus wheel. Second, remember that the game is moderate volatility. Although the game is relatively even-toned relative to many buffalo slot machines, losing streaks can occur. Thirdly, avoid aggressively chasing the grand jackpot. A 5,000x win is extremely appealing, however it will rarely come. Fourthly, utilize demo mode prior to attempting to play for real cash if you're unfamiliar with sticky-symbol mechanisms.
