Bison Prime Power Combo is a feature-rich online slot from Just For The Win that blends classic line wins with creative bonus rounds. The game is set in a prairie landscape where bison, wolves and eagles take over the reels. Its highlight is the trio of bonus modes that combine in different ways, with Bison symbols at the heart of all the action. All in all, it’s a modern take on animal-themed slot games that adds extra layers through its collection features and power combos.
The game’s visual setup places you in a scenic, open plain backed by mountain ranges and a sunset sky. Everything looks vibrant and well-balanced visually. The animal symbols are sharp and detailed, framed in gold and easily recognisable. Animations are smooth, especially when the Bison symbols hit or when Free Spins kick in. The design has a bit of a cartoon shine to it but still feels slick and polished. Music and sound effects are upbeat and tie in well with the game’s theme, helping keep the energy up with each spin. Nothing feels cluttered or overly busy, which is great if you prefer a clean and focused design.
Here’s how the payouts line up for each symbol based on a 5.00 credit bet:
Symbol | 3 of a Kind | 4 of a Kind | 5 of a Kind |
Eagle | 5.00 | 10.00 | 40.00 |
Cougar | 2.50 | 5.00 | 20.00 |
Wolf | 2.50 | 5.00 | 20.00 |
Elk | 2.50 | 5.00 | 15.00 |
A, K, Q, J, 10, 9 | 1.00 | 2.50 | 5.00 |
The Bison symbol only appears in the centre of the third reel during the base game. When it lands, it collects all money symbols that are visible. If two Bison symbols land at once, it collects everything twice. It also substitutes for all symbols except tokens and money symbols to help create wins.
Money symbols appear randomly and hold values like 0.5x, 1x, up to 4x your current bet. Some of them can even trigger fixed jackpot prizes:
In Free Spins, some money symbols may contain a +1 spin instead of a cash value.
Landing token symbols gives you a chance to trigger Free Spins. Each token represents a feature. If you land more than one type at the same time, you’ll unlock more features:
Each round begins with 6 Free Spins. If you land a new feature token during the round, you’ll get 3 extra spins added on.
When this feature is active, Bison symbols in Free Spins carry a multiplier. It can be x2, x3, x4 or x5 and applies to whatever value is collected from the money symbols. If more than one Bison symbol with multipliers is involved, the values are either added or applied individually depending on the situation.
With this feature turned on, the Bison symbol appears on every Free Spin. This increases the chance of collecting money symbols each spin, making it easier to trigger fixed prizes.
This feature changes where Bison symbols can appear. Instead of just the middle reel, they can also show up in the centre of reels 2 and 4. This makes it more likely to land two Bison symbols in the same spin, which results in double collections.
This game is played on a 5-reel, 3-row layout with 20 fixed paylines. Wins are paid from left to right on adjacent reels, starting from the far left. Matching symbols must land on a fixed payline, starting from the first reel. The core mechanics remain simple, but the bonus features add most of the depth. You can land wins the standard way through matching symbols, but also through the coin collection mechanic with the Bison symbol. It’s a mix of standard structure and feature-driven gameplay.
Bison Prime Power Combo keeps things moving with regular action and smart use of features. The game is easy to follow, even with its multiple bonus modes. What works well here is the way the Bison symbol functions as more than just a Wild. It connects the whole game together by collecting coin values and triggering the fixed prizes. The token system for Free Spins is also a nice touch, since it gives you different combinations to play through. If you enjoy slots with layered features and frequent symbol interaction, this one is worth checking out. The visual style and straightforward layout help round things out nicely.
