Pragmatic Play established a franchise with its Release series, beginning with the inaugural kraken-themed title in 2020 and following with a sequel two years later. Release the Bison arrived in April 2024 as the third entry, shifting the thematic focus entirely while introducing mechanical adjustments throughout. While franchise lineage remains evident, this installment charts a more conservative path than its predecessors.
The game presents an expansive natural environment featuring mountainous terrain, sprawling grasslands, and vegetation elements. This wilderness setting establishes visual appeal and atmospheric grounding. The character symbols possess a distinctive artistic style with exaggerated facial characteristics, though their stylized nature may strike some as unconventional. Regardless of aesthetic preferences, the mechanical foundations warrant examination, and Release the Bison reveals certain constraints when compared directly to preceding titles.
The architecture spans five reels across three rows with twenty permanently active paylines evaluating winning combinations. Bet flexibility accommodates stakes anywhere from twenty cents to two hundred and forty dollars per spin, ensuring accessibility for both conservative players and aggressive punters. An optional ante bet increases the base stake by fifty percent, statistically elevating the probability of triggering free spins bonuses.
The paytable arranges symbols into two tiers. Traditional playing cards from ten through ace comprise the lower-value grouping, while four premium animal characters constitute the upper tier. Five identical card ranks yield payouts from half a bet to one and a half times the wager. Premium animal symbols deliver more generous compensation, with maximum five-of-a-kind payouts ranging between twice the bet and ten times the bet. Bison wilds manifest across all reels and function as substitutes for standard pay symbols. Five consecutive bison symbols generate payouts reaching twelve and a half times the stake.
The default theoretical return to player sits at 96.54 percent, a respectable figure presenting no concerns. Volatility reaches the maximum end of the spectrum. Winning combinations appear infrequently compared to gentler variance games, yet individual wins tend toward substantial magnitudes. Approximately one winning combination materializes roughly once per three and a half spins. The scatter-triggered free spins bonus appears approximately once every two hundred sixty-two spins. The theoretical maximum payout reaches three thousand times the wagered amount, an extraordinarily improbable outcome occurring with estimated frequency of approximately once every sixteen million spins.
The bonus system encompasses four mechanisms: repositioning wild respins, randomly-generated base-game windfalls, scatter-activated free spins, and direct purchase access. The wild respin sequence activates with four or more simultaneous wild symbols. The reel mechanism locks while wilds reposition randomly following each subsequent spin. The game evaluates and processes winning combinations during each respin cycle. When additional wilds appear during respins, they extend the spin counter while becoming additional roaming symbols. A cumulative multiplier escalates by one for each fresh wild addition. Scatter symbols accumulate during this sequence, with three or more triggering free spins immediately.
The windfall feature operates during base-game spins generating no winning outcome, substituting an unexpected payout scaling from ten to forty times the bet. Free spins require minimum three scatters. Two scatters may randomly trigger an optional respin targeting reels lacking scatters. When free spins commence, a wheel determines both spin quantity and multiplier. Parameters fluctuate based on scatter count: three scatters award eight to eighteen spins with multipliers from one to five times; four scatters provide the same spin range with multipliers starting at two times; five scatters deliver ten to eighteen spins with multipliers commencing at three times.
During free spins, every landed wild becomes a persistent roaming wild remaining throughout the bonus sequence. These wilds shift to random positions between individual spins. The game maintains a running counter for each collected wild. Beginning with the fifth accumulated wild, players receive one supplementary free spin plus one multiplier unit increase, reaching maximum accumulation of ten wilds. Players can purchase direct free spins access from the base game: eighty bet units simulates a three-scatter trigger, one hundred fifty simulates a four-scatter trigger, and three hundred simulates a five-scatter trigger. These purchased entries operate with marginally adjusted RTP calculations.
The transition from the prior sequel incorporated multiple mechanical streamlining decisions resulting in less intricate gameplay. Pragmatic Play eliminated the shifting stack mechanism from its predecessor, reduced base-game windfall scope, and removed distinctive bonus-round structures providing outcome variety. Free spin allocations may have increased modestly, but this benefit is negated by reduced multiplier thresholds and elimination of payline multiplication during bonuses. Maximum winning potential contracted from five-thousand times in the predecessor or ten-thousand times in the original down to three-thousand times here. These modifications reflect a developer strategy favoring mechanical reduction and outcome constraint over expanded entertainment.
From an evaluation perspective, these changes resist characterization as progress. The game remains mechanically sound with acceptable baselines, but lacks innovative features distinguishing earlier titles. Each modification appears motivated by risk mitigation rather than player experience enhancement. Gamers accustomed to substantially more generous reward structures may encounter disappointment discovering the compressed ceiling and restrained multiplier construction. Assessed independently, Release the Bison functions adequately as a high-variance title. Positioned within the Release franchise trajectory, it registers as a cautious mechanical retreat—professionally executed but demonstrating less ambition than established standards.
