What is the Release the Bison Demo?

Release the Bison introduces a base game mechanic that most Pragmatic Play high-volatility slots do not bother with: an active wild respin state that fires before the scatter trigger. Land four or more wilds on the same spin and the slot enters respin mode, where all wilds roam the reels between each respin while the multiplier climbs by one per round. Scatters collected during the respin chain count toward the free spins trigger, which means the wild respin is not just an incidental payoff on its own terms but also a secondary path into the bonus. Whether the game needed that additional layer or whether it compensates for other trade-offs is worth understanding before the first spin.

The demo loads in your browser without registration or deposit, running the same math model and features. If you want to see how it fits among similar Pragmatic Play releases, the free demo slots library has the broader portfolio available for comparison.

Release the Bison Base Game

Release the Bison Slot Review: Our Expert Verdict

Theme, Graphics, and Sound

The setting is an outdoor landscape with mountains, meadows, and trees visible behind the reels. It is a genuinely pleasant environment, cleaner and less crowded than a lot of Pragmatic Play's themed backdrops. The animal symbols that appear on the reels carry slightly unusual expressions that register as odd rather than charming, which is a minor design note but noticeable enough to mention.

The 5x3 grid is standard. The wild respin state creates a distinct visual mode when it fires: wilds migrate across the reels between each respin, and the multiplier counter increments visibly. During testing this respin mode was the most engaging visual element in the base game, which is its purpose. The free spins wheel that appears before the bonus round starts, determining both the spin count and the starting multiplier based on how many scatters triggered it, adds a brief moment of variable entry that gives the trigger result some information content rather than being a fixed outcome.

Base Game and Key Features

The base game runs on a 5x3 grid with 20 paylines. Bison wilds land on all reels and substitute for regular pay symbols. The Ante Bet option increases the stake by 50% in exchange for a higher scatter frequency, which is relevant if you want to trigger free spins more often but accept the associated balance cost. Using a bonus with wagering requirements limits how much the Ante Bet is worth, since the higher spend per spin accelerates the wager without proportionally improving the trigger rate enough to offset the balance drain in most sessions.

• Wild Respins Feature: four or more wilds on the same spin activates respin mode. All wilds become roaming wilds, moving to random positions between each respin, while a win multiplier increases by +1 per respin. Any new wild landing during the feature adds another respin and also roams. Scatters that land during the chain are collected; three or more collected scatters at the chain's end trigger free spins.
• Guaranteed Win: at random intervals, a non-winning base game spin converts to a guaranteed win worth 10x to 40x the stake.
• Free Spins: triggered by three or more scatters. Before the round begins, a wheel awards both a spin count and a starting multiplier, with the ranges determined by how many scatters triggered: three scatters gives 8 to 18 spins and a multiplier of 1x to 5x; four scatters gives 8 to 18 spins and 2x to 5x; five scatters gives 10 to 18 spins and 3x to 5x. During the round, wilds become permanent roaming wilds that stay until the round ends. A wild meter tracks collected wilds; from the fifth collected wild onwards, each additional wild adds one free spin and increases the multiplier by 1, up to 10 additional wilds for a maximum of 10 extra spins and a 10-point multiplier increase.
• Feature Buy: the free spins can be purchased for 80x the stake (3-scatter trigger), 150x the stake (4-scatter trigger), or 300x the stake (5-scatter trigger), with slightly different RTP figures at each level.

Verdict

The wild respin mechanic is the most interesting thing Release the Bison does, and it works because it creates an outcome in the base game that has both an immediate payoff and a secondary routing function. When the respin chain accumulates enough scatters, it delivers free spins at the end of an already active sequence rather than requiring a cold scatter landing. That two-path structure makes the base game more eventful than a slot that waits passively for the scatter trigger.

The trade-offs are real. The 3,000x cap is the honest figure at high volatility, and the free spins wheel introduces variance in the starting multiplier that can produce an opening spin count and multiplier combination that makes the bonus feel short before it starts. The guaranteed win feature adds intermittent base game activity, though 10x to 40x on random non-winning spins is a marginal contribution. Release the Bison is a functional high-volatility slot with a well-designed base game state and a free spins multiplier that builds through wild collection. It does not have the peak potential of the higher-upside Pragmatic Play releases, and the structure makes that trade-off clearly.

Max Win and RTP Explained

What does the RTP mean for players?

Release the Bison carries an RTP of 97.49% per the game's labeled stats, which is a high figure for a Pragmatic Play title and worth confirming in the in-game paytable at whichever operator you use, since the game is available in multiple RTP configurations. At high volatility, the return concentrates into wild respin events and free spins rather than distributing evenly across standard spins. Operators who configure games at reduced settings without disclosure are a persistent issue in this space, and the casinos to avoid list identifies operators with a documented pattern of running the lower configurations.

How hard is it to hit the max win?

The cap is 3,000x the stake, reachable when the free spins round produces sustained wild collection with multiplier increases alongside high-value win lines across the full spin count. The starting multiplier from the wheel (up to 5x) combined with additional multiplier increases from wild collection (up to +10) means peak multiplier conditions require both a high wheel outcome and significant wild activity within the round. Release the Bison launched in April 2024 and is available across most operators, including at new casino sites that added it around that period. The one-in-sixteen-million frequency for the maximum outcome is an accurate representation of how far the 3,000x figure sits from the typical session result.

Conclusion

Release the Bison is a high-volatility Pragmatic Play slot with a base game state worth having: the wild respin chain is active, can build a meaningful multiplier, and routes into free spins when scatters collect during it. The free spins themselves use a wheel-based start and a wild meter that extends the round and the multiplier, which provides a clear internal logic to how the maximum outcome is reached. The 3,000x cap is lower than other high-volatility releases in this space, and the wild respin trigger (four or more wilds) is a condition that does not arise on every session. For someone who wants a Pragmatic Play high-volatility slot with a more active base game than the standard scatter-wait model, Release the Bison delivers that in a specific and functional way.

What is the volatility of Release the Bison?

Release the Bison is rated High volatility. In practice the base game produces intermittent activity from the wild respin and guaranteed win features, but the significant session outcomes concentrate into free spins rounds. The wild respin can occasionally deliver standalone wins with its growing multiplier, but the 3,000x cap is reached through the free spins wild meter and multiplier accumulation. Someone looking for a high-volatility slot with more base game activity than the standard Pragmatic Play scatter-wait formula will find Release the Bison fits that description better than most of the studio's output.

Who makes Release the Bison?

Pragmatic Play developed Release the Bison. The studio previously released Release the Kraken in 2020 and Release the Kraken 2 subsequently, with Release the Bison extending the series to a different animal and a modified feature structure. Pragmatic Play's high-volatility portfolio frequently uses a roaming wild format where wilds move between spins during a bonus state, a pattern visible across several of their releases.

How does the Release the Bison wild respin feature work?

When four or more bison wilds land on the same spin, the slot enters respin mode. Every wild on the board becomes a roaming wild, shifting to a random position between each respin while the game pays any wins formed. A multiplier counter starts at 1 and increases by one for each respin that occurs. Any new wild landing during the chain extends the respin by one more round, adds the new wild to the roaming group, and increments the multiplier. Scatters that land during the chain are collected; if three or more accumulate by the time the chain ends, free spins trigger. The practical result is that a strong wild respin chain can both pay directly through its multiplied wins and deliver free spins at the end without requiring a separate scatter trigger.
