Jelly Slots: Games, RTP and the Free 4 Bad Guys Mechanic
Jelly is a Norwich-based slot developer founded in 2020, building regulated real-money slots as part of Yggdrasil’s YG Masters partner programme. Rather than owning its own distribution network, Jelly develops on Yggdrasil’s GATI toolkit, which handles regulation-ready compliance and routes finished games out through Yggdrasil’s wider casino network. The studio has released a steadily growing catalogue since joining YG Masters, including Big Benji Bonanza, Achilles, Buffalo Blox Gigablox and the superhero-themed Adventures of Captain Cash. SlotsLike currently reviews one Jelly release in full, Adventures of Captain Cash, with more to follow as the studio’s back catalogue is worked through.

Big Benji Bonanza is one of Jelly’s better-known releases, a Wall Street themed 5×3 slot built on 243 ways to win, with caricatured US president symbols carrying individual cash multipliers and a Buy Bonus route into its Super Staxx free spins. It gives a good sense of Jelly’s house style: a fairly traditional reel structure dressed in a strong, slightly comic theme, with a purchase-based bonus route layered on top.

A sci-fi superhero slot built around the Free 4 Bad Guys mechanic, splitting the bonus round across four villain-specific free spins modes, worth up to 2,500x stake.
Elsewhere in the catalogue: Big Benji Bonanza applies the same purchase-based bonus idea to a Wall Street theme with 243 ways to win, Achilles and Valhalla Saga: Thunder of Thor cover Greek and Norse mythology respectively, Buffalo Blox Gigablox and Burning Blox Gigablox pair coin scatter jackpots with the Gigablox oversized-symbol format, and Savanna Roar and Fury of Hyde Megaways round out the studio’s wildlife and horror-adjacent releases. None of these are reviewed on SlotsLike yet.
Features Jelly Is Known For
Purchase-Based Bonus Access
Most Jelly releases pair a natural bonus trigger with at least one purchase route, whether that is a straight Buy Bonus, a Side Bet that raises the odds without guaranteeing a trigger, or a Golden Bet style stake increase. Adventures of Captain Cash runs all three at once. See more Buy Bonus Feature slots for how widely other studios reuse the same idea, and check the exact operator before assuming any purchase route is switched on for UK players.
Character-Specific Free Spins
A second recurring Jelly mechanic splits a single bonus round across several different characters, each with a distinct modifier rather than one shared free spins mode. Adventures of Captain Cash’s Free 4 Bad Guys structure is a direct example, sending players into one of four separate villain-themed rounds depending on which bad guy breaks free. Compare this with other Free Spins slots from different studios to see how differently the idea gets implemented elsewhere.
Related Theme
Adventures of Captain Cash puts Jelly’s output into superhero and sci-fi territory, dressing the studio’s usual purchase-based bonus mechanics in a caped-hero setting. Browse more Superhero theme slots for other studios’ takes on the same idea.

About Jelly
Founding and YG Masters
Jelly was founded in 2020 and is based at Norwich Research Park in England. The studio joined Yggdrasil’s YG Masters programme in October 2020, one of a wave of smaller independent studios Yggdrasil brought on board to design and distribute content through its existing operator network. That partnership gives Jelly access to Yggdrasil’s GATI development toolkit, a preconfigured, regulation-ready framework that shortens the route from a finished game to a licensed operator’s lobby without Jelly having to build its own compliance and distribution infrastructure from scratch.
House Style
Jelly’s catalogue leans on fairly conventional reel structures, mostly 5×3 or 5×4 grids with fixed paylines or a set number of ways to win, rather than the tumbling cluster-pays or Megaways-style grids many newer studios favour. What distinguishes the studio’s output is how consistently it layers extra bonus-access routes on top of that traditional base: Buy Bonus, Side Bet and Golden Bet style options appear across a large share of the catalogue, sometimes two or three on the same title, as seen on Adventures of Captain Cash. A second recurring idea splits bonus rounds across multiple characters or symbols with distinct modifiers rather than a single fixed free spins mode, giving even a conventional-looking base game some genuine variety once the bonus triggers.
Licensing and Regulated Markets
Jelly’s games reach players through Yggdrasil’s licensed operator network, and UK availability depends on the individual operator’s own Gambling Commission licence. As with any studio offering purchase-based bonus features, UK-licensed builds do not always carry every purchase route a game’s international version supports, so it is worth checking an operator’s own game information screen rather than assuming a feature described elsewhere is switched on.
