Barcrest's gothic double act where Big Bet spins push RTP to 98%.
Dr. Jekyll himself acts as the wild symbol, substituting for every regular symbol except the scatter to help complete more winning combinations.
Wager 20, 30, 40, or 50 coins to play five linked spins; landing scatters during this feature adds extra positions that can pay out up to 75 free spins once the final spin resolves.
Landing three or more scatter symbols anywhere on the reels awards up to 20 free spins, with two wilds appearing during the feature adding even more spins.
When the potion symbol lands with a joker, Hyde Spins kick in, handing you a sticky wild that substitutes for everything except the Sand Timer symbol until it lands on the fifth reel.
Hyde Spins can keep extending themselves, potentially returning extra free spins or continuing the feature outright so your winnings keep climbing.
Choose a bet between 0.10 and 50 coins per spin across the 5 reels and 10 fixed paylines before you start.
Watch for card symbols, test tubes, scrolls, street lamps, Big Ben, and the Emperor to land winning combinations.
Opt into the Big Bet feature for a higher per-spin cost in exchange for a shot at up to 75 free spins.
Three or more scatters unlock up to 20 free spins, while a potion and joker combo triggers the Hyde Spins bonus round.
The Big Bet feature is the signature mechanic here: players stake 20, 30, 40, or 50 coins to play five linked spins, and any scatter that lands during those spins adds an extra position on the reel road. Once the final Big Bet spin resolves, all those accumulated positions convert into a free spins reward that can climb as high as 75 spins, making the higher upfront cost a calculated gamble for a much bigger free spins haul than the standard scatter-triggered round offers.
Barcrest built Dr. Jekyll Goes Wild around the fog-drenched streets of Victorian London, drawing directly from Robert Louis Stevenson’s 1886 novel about a lawyer investigating the terrifying duality of his friend Dr. Henry Jekyll. That literary DNA shows up everywhere on the reels: landmarks like Big Ben sit alongside test tubes, scrolls, and street lamps, and the entire background scene shifts to a red-tinted London street once Hyde Spins kick in. The soundtrack leans hard into that dread, ramping up the tension every time a spin lands.
Mechanically, this is a 5-reel, 10-payline slot with medium volatility, a stated RTP of 98%, and stakes running from 0.10 to 50 coins per spin. Dr. Jekyll himself acts as the wild, substituting for everything except the scatter, while three or more scatters unlock up to 20 free spins. The real draw is the optional Big Bet feature — paying 20 to 50 coins per spin for five linked rounds that can snowball into as many as 75 free spins, with a top jackpot worth 500x your original bet.
