Dr Jekyll Goes Wild Slot Review
Barcrest have long built their reputation on classic UK-style video slots with a twist, and Dr Jekyll Goes Wild is no exception. Released in June 2017, this Victorian-themed slot draws from Robert Louis Stevenson’s gothic tale to deliver a game centered around a progressive trail system. The Big Bet feature differentiates this release from standard Barcrest offerings, allowing players to opt for linked spins with enhanced free spins potential. Those familiar with Barcrest’s design language will recognise the 5×3, 10-payline structure, though the dual personality mechanics and scatter trail add layers beyond their typical formula.
Base Game & Features
The game operates on a 5-reel, 3-row grid with 10 fixed paylines. Wins form via standard left-to-right combinations across these paylines, with symbols paying out 10x, 25x, or 60x your bet for landing 3, 4, or 5 matching symbols. The paytable divides into two distinct groups: high-value thematic symbols and low-value card icons.
Symbol Breakdown
The higher-paying symbols reflect the Victorian theme, including Street Lamps, Test Tubes, Big Ben clock tower, ancient Scrolls, a Sand Timer, and the Emperor. These thematic icons deliver the stronger payouts and tie directly into the game’s dual personality narrative. The lower-paying symbols use standard playing card values: 10, J, Q, K, and Ace, styled with gothic typography to maintain visual cohesion.
Wild Symbol Mechanics
Dr Jekyll serves as the wild symbol, substituting for all symbols except the scatter. Standard wild functionality applies here–it completes winning combinations by filling gaps on active paylines. During free spins, the wild takes on additional significance, with 2 or more Jekyll wilds triggering extra free spins (2 wilds award 3 spins, 3 wilds award 10 spins). This retrigger mechanic adds volatility to the bonus round, particularly when combined with Big Bet mode.
Scatter Symbol & Trail System
The split Dr Jekyll/Mr Hyde icon functions as the scatter. Unlike many slots where scatters simply trigger free spins, this game uses a progressive trail system. Each scatter that lands adds one position to the trail, with higher positions on the trail awarding more free spins when the bonus eventually triggers. This accumulation mechanic is most impactful during Big Bet mode, where scatter frequency increases across 5 linked spins.
Dr Jekyll Goes Wild Free Spins
Free spins trigger via 3 or more scatter symbols, with the number of scatters determining the base award: 3 scatters award 10-12 free spins, 4 scatters award 15 free spins, and 5 scatters award 20 free spins. These baseline amounts sit comfortably in the medium range for video slots, though the retrigger potential elevates the feature’s upside.
Hyde Spins Mechanic
During free spins, landing the Potion symbol alongside a Jekyll Wild triggers unlimited Hyde Spins. These continue until the Sand Timer symbol appears on reel 5, at which point the feature concludes and accumulated wins are paid. The unlimited nature of Hyde Spins introduces genuine volatility, though the Sand Timer’s appearance frequency keeps sessions from extending indefinitely. This mechanic ties thematically to the Jekyll/Hyde transformation narrative while adding mechanical variance.
Big Bet Mode & Enhanced Free Spins
The Big Bet feature allows players to wager £20, £30, £40, or £50 per spin for a series of 5 linked spins. All wins accumulate and pay at the end of the sequence. More importantly, scatter symbols collected during Big Bet spins advance the trail system, with maximum scatter positions awarding up to 75 free spins. The RTP increases significantly in Big Bet mode, reaching 98.2% compared to the 94.2%-96% range in standard play.
The Big Bet structure requires commitment–players can’t exit mid-sequence–but the improved scatter frequency and RTP make it the optimal path for those chasing the free spins bonus. This isn’t a casual feature; it’s designed for sessions where bankroll depth supports sustained premium wagers.
Our Honest Verdict
Dr Jekyll Goes Wild sits firmly in Barcrest’s wheelhouse: medium volatility gameplay with a feature-focused design. The Big Bet system differentiates this from their standard catalogue, offering a premium option that significantly boosts RTP and free spins potential. Players comfortable with £20-£50 per spin will find the linked spins mechanic worthwhile, particularly given the trail system’s ability to unlock up to 75 free spins.
That said, the standard play experience feels constrained. With RTP ranging from 94.2% at lower stakes to 96% at standard bets, the game lacks the generosity found in many modern releases. The 10-payline structure and 500x stake maximum win position this as a mid-range slot, not built for massive multipliers. Those seeking 5,000x+ potential should look elsewhere–this caps at more modest wins even with full free spins unlocked.
The Hyde Spins unlimited mechanic adds intrigue during free spins, though the Sand Timer’s appearance frequency prevents extended runs from becoming the norm. We didn’t see it trigger often during testing, suggesting it’s more of an occasional highlight than a reliable feature. The dual personality theme is well-executed visually, but mechanically it’s window dressing–scatter trails and linked spins are the real draw here.
Who this suits: Players who appreciate Barcrest’s traditional style with a premium betting option. The Big Bet feature will appeal to those with larger bankrolls seeking improved RTP and enhanced free spins potential. Medium volatility (23.41% win frequency) keeps gameplay balanced rather than feast-or-famine.
Who should skip it: High variance chasers looking for explosive multipliers, and casual players uncomfortable with Big Bet’s £20-£50 commitment per spin. Standard play lacks the excitement and RTP generosity to compete with more recent releases. The 500x cap won’t satisfy those accustomed to modern slots offering 10,000x+ potential.
Final positioning: A solid mid-tier Barcrest release that delivers what it promises but doesn’t exceed expectations. The Big Bet feature is genuinely innovative for its time (2017), though by 2025 standards it feels less unique. It will more than suffice for fans of Barcrest’s design philosophy, though those new to the developer might find more polished mechanics elsewhere in their catalogue.
Rating: 7/10 – Well-executed within its niche, limited by capped wins and RTP variance across bet levels.

The RTP varies depending on your betting mode. Standard play at lower stakes offers 94.2% RTP, while standard betting reaches 96% RTP.

What is the maximum win on Dr Jekyll Goes Wild?
The maximum win is 500x your stake in standard play. At the £100 maximum bet, this equals £50,000. While respectable, this cap positions Dr Jekyll Goes Wild below modern high-volatility slots that often offer 10,000x+ multipliers. The 500x limit reflects the game’s medium volatility design. -

The interface adapts well to smaller screens, with all features including Big Bet mode accessible via touchscreen controls. -
Does Dr Jekyll Goes Wild have a bonus buy feature?
Not in the traditional sense. Dr Jekyll Goes Wild doesn’t offer a direct ‘bonus buy’ where you purchase free spins. Instead, it features Big Bet mode (£20, £30, £40, or £50 per spin), which significantly increases your chances of triggering free spins via the scatter trail system. Big Bet mode also boosts RTP to 98.2% and can unlock up to 75 free spins. While not instant access, it’s a premium betting option designed to enhance bonus frequency. -
What is the volatility of Dr Jekyll Goes Wild?
Dr Jekyll Goes Wild is classified as medium volatility. The game has a 23.41% win frequency (hits approximately 1 in every 4.3 spins), which sits squarely in the balanced range. This means you’ll see a mix of regular smaller wins and occasional larger payouts, rather than the extended dry spells of high-volatility slots or the frequent tiny wins of low-volatility games. The medium variance suits players seeking consistent base game action with decent bonus potential.
