Bison Storm (TrueLab Games) – Review & Demo Play

Bison Storm Slot Overview

I headed into Arizona’s canyons with Bison Storm by TrueLab, a high volatility slot on a 6 by 4 grid with 4096 ways to win. The set-up feels clean, with wild symbols, scatters, and a free spins game that can reach 100 spins. Hot Mode steps in to strip low symbols from the bonus, while wild multipliers pile on in the round. The headline max win sits at 25,000x, and the theme lands well thanks to calm nature sounds and a tidy wooden frame.

Bison Storm Slot Information

To land a win in Bison Storm I needed three or more matching symbols on adjacent reels starting from the leftmost. The game runs smoothly across mobile, tablet, and desktop. The valley backdrop with sand coloured mountains and a bright blue sky sets the tone without clutter. I liked how the interface keeps the focus on the reels. The logo sits to the side, with a small creek in view, and the audio leans on nature sounds that never get in the way of the spins.

On the numbers side Bison Storm posts an RTP of 96.05 percent with high volatility and a max payout of 25,000x the bet. Some venues may offer lowered RTP versions such as 95.01 percent, 92.01 percent, or 89.15 percent, so I always check the info panel before I start. The 6 reel 4 row layout gives 4,096 ways from the off, which keeps base play moving. The math leans swingy, though the bonus can turn quickly when multipliers connect.

Bison Storm Symbols and Paytable

The lower paying symbols in Bison Storm are 9, 10, J, Q, K, and A, paying between 2x and 3x for six of a kind. The higher tier carries cougar, eagle, wolf, bear, and bison, paying between 5x and 7.5x for a six symbol hit. Wins count on adjacent reels from left to right, so ways often link neatly when the screen lines up. This mix gives steady small hits while the animals can spike harder during the feature.

The Wild Symbol is a gold coin that appears on reels two to six and substitutes for all except the Scatter Symbol. In the bonus, those wilds can carry a random multiplier of 2x, 3x, or 5x, which is where the paytable feels alive. Scatter Symbols trigger the free spins when they land anywhere, with the exact count tied to how many appear. I found the reels clearest when Hot Mode removed the card ranks from the round.

Bison Storm Slot Features

The Free Spins in Bison Storm start with three to six scatters anywhere on the reels. Three scatters award 8 free spins, four give 15, five give 25, and six grant 100 spins. During the round you can retrigger with 2, 3, 4, 5, or 6 scatters for an extra 5, 8, 15, 25, or 100 spins accordingly. The flow feels fair, and the best sequences stack up when wilds land early and keep reappearing across the middle reels.

Hot Mode can trigger before the bonus to remove low value symbols from the feature, leaving only the high and medium icons. That shift tightens the hit quality and helps the multipliers land on better lines. Hot Mode can also appear during free spins if at least two scatter symbols hit, which adds a nice spike. When this came in for me, the screen stopped throwing away wins to the small cards and the animals did the heavy lifting.

Wild Multipliers operate only in the free spins. When a wild with a multiplier takes part in a win, it applies its value. If more than one joins the same way, they multiply together before hitting the total. A x2 with a x3 becomes x6, and that is where the slot can run. Multipliers do not carry over to the next spin, so every spin is fresh. The system rewards stacked wilds that touch the best animals.

Feature Buy in Bison Storm

The Buy Bonus offers a fast route into the action with 8 free spins at a cost of 100x the bet, and it can still trigger extra spins and Hot Mode. There is a Super Free Spins option priced at 1000x that brings a higher chance of landing Wild Multipliers and Hot Mode from the start. Published figures list RTP around 96.17 percent for the standard buy and 96.13 percent for the super buy. I used this when base play felt slow.

Bison Storm Demo Version

I always test the Bison Storm demo version first to learn the flow of the features and the bite of the multipliers. It is a handy way to try free spins pacing, see Hot Mode behaviour, and gauge how 4,096 ways connect across the 6 by 4 grid. The demo helps set bet sizing plans for real play and gives a feel for volatility. After a few sessions I knew when to chase the feature and when to step back.
