Bison Battle Slot Review

Bison Battle Slot Overview

Bison Battle drops you straight into Indian territory, with a Grand Canyon style display behind the reels and Native American touches scattered around the frame. The set-up uses 5 reels and 20 paylines, and you can spin from 10p up to 100 quid a go on any device. The mood shifts nicely as you move between the base game, the snowy Ice Park and the lush Green Valley bonus rounds.

For the maths, Bison Battle runs on high volatility with a default RTP around 96.4 percent, though the provider offers several RTP versions to casinos. The max win is a hefty 50,000 times your stake, and the listed win cap probability sits at 1 in 4,830,920 spins. It is a proper high risk set-up, so I always treat it as a game for measured, session-based play rather than quick punts.

Bison Battle Slot Information

The reels in Bison Battle are packed with classic card suit symbols for the low pays, with diamonds, spades, clubs and hearts paying 2x your bet for a full line of five. Premium symbols are a lynx, wolf, bear and bald eagle, and five of a kind pays from 10x to 50x your stake. Two eagles already give a small hit, which helps during the long spells between the heavy punches.

The golden Wild Bison symbol is the regular wild in Bison Battle, stepping in for all standard pays and doing its best work when it lines up with those top-tier eagles. Scatter duties sit with three coloured bison symbols, blue, green and red, each tied to a specific feature. All this plays out over a soundtrack of drums and atmospheric tones that fits the North American wildlife set-up rather nicely.

Bison Battle Slot Features

The heart of Bison Battle is the Red Bison symbol that can land on reels one and five. On reel one it carries an instant prize from 5x up to 2,500x your stake and walks one reel right each spin if there is no partner. On reel five it shows a multiplier from x1 to x10 and walks left. When the two clash on the same row, you pocket the prize multiplied.

That Bison Clash can throw out serious wins in the base game, up to around 25,000x if you hit the dream pairing, but it will tease just as often. You see plenty of Red Bisons marching across the grid only to step off the reels without meeting anything, which can be frustrating. For me, though, that constant potential keeps the base game from feeling flat even during weaker stretches.

Blue and Green Bison scatters only hit on reel one, and when they share a row with a Red Bison on reel five they trigger the two bonus rounds. Green plus red kicks off Green Valley, while blue plus red launches Ice Park. The way these bisons clash and charge across the reels gives the whole game a lively, rolling pace, and both features can swing a session very quickly.

Ice Park Feature in Bison Battle

Ice Park in Bison Battle is a hold-and-win style streak respin feature that starts with 3 spins on an icy version of the canyon. Only Bison Coin symbols and blanks land on the middle three reels, while Red Bison multiplier symbols and blanks hit reels one and five. Every time a coin or bison lands, the spin counter resets, and any bison charges across its row to multiply all coin values it passes.

Green Valley Feature in Bison Battle

Green Valley in Bison Battle is the free spins bonus that plays out in a verdant version of the canyon. You get 8 free spins to start, and during this feature Wild Bison symbols only land on reels two, three and four, where they turn sticky for the rest of the round. Red Bison symbols with multipliers from x2 to x10 can appear on reels one and five and award one extra spin apiece.

The red bisons are not just there for extra spins in Green Valley, though. When one lands on a row that already holds sticky wilds, it charges across and adds its multiplier to every wild on that row. During my better runs the screen filled with upgraded sticky wilds, and the wins ramped up sharply towards the end of the bonus. It can still whiff, but the set-up has serious punch when it goes.

Bonus Buy in Bison Battle

For players who can use it, Bison Battle comes with a Bonus Buy menu that lets you jump straight into the action. Green Valley costs 75x your stake and nudges the RTP to about 96.58 percent, while Ice Park costs 95x with RTP around 96.69 percent. The provider quotes that either bonus round will normally land through natural play roughly once every 267 spins, though my samples have varied a fair bit.

Bison Battle Slot Verdict

From a seasoned slot player’s point of view, Bison Battle hits that sweet spot where familiar North American animal visuals sit on top of some properly inventive mechanics. The walking Red Bisons and their clashes create constant sweat in the base game, even though plenty of them end up wasted. Adjustable RTP ranges are worth checking in the help files, but on the higher settings the maths profile feels very attractive.

Both Ice Park and Green Valley have their own flavour, and I have seen either one rip a balance from nothing much to hundreds of times stake in a handful of spins. You are playing for a capped 50,000x win with a probability of around 1 in 4,830,920, so those unicorn moments will be rare. If you enjoy volatile, hard-bucking slots with strong bonus rounds, Bison Battle is well worth a proper look.
