Jelly Entertainment API: British humour on Megaways, Gigablox and DoubleMax reels

A Norwich studio built on proven mechanics

Jelly Entertainment is a UK developer of real-money slots, established in 2020 and based at Norwich Research Park in Norfolk. Its first game, Savanna Roar, went live in October 2021 and is still a regular in its most-played list.

Instead of inventing a new reel engine and asking players to learn it, Jelly took a different route. The studio joined Yggdrasil's YG Masters programme and Stakelogic's Greenlogic programme, which gave it access to recognised mechanics: Gigablox and DoubleMax from Yggdrasil, the Megaways engine created by Big Time Gaming, and link-style features. Jelly then brings its own themes, art and humour to those engines. The result is a catalogue that feels instantly familiar to experienced players but still has a personality of its own.

What makes a Jelly slot fun to play

Jelly slots are built for players who like a laugh with their spin. The titles alone set the tone: Big Benji Bonanza winks at a London landmark, Fury of Hyde borrows from the Jekyll and Hyde story, and CleoPatrick is a pun before the reels even spin. The humour gives the games a clear identity in a lobby full of serious fantasy art.

Under the jokes, the maths is serious. Many Jelly titles sit in the medium-high to high volatility band with top wins above 10,000x the stake, so they appeal to players who chase features. Because they run on mechanics these players already know, there is no learning curve: a Megaways fan knows what to expect from Fury of Hyde, and a Gigablox player recognises Buffalo Blox at once.

That combination is useful for operators. Jelly content refreshes a Megaways or "big feature" category with new themes, without asking players to trust an unknown engine.

Getting Jelly slots live on SoftAggregator

Jelly runs on the same integration as every other studio in our casino game aggregator API. You send JSON POST calls to one endpoint, identify yourself with api_login and api_password, and choose the operation with the method field.

1. getProviderList: find Jelly Entertainment and note its provider key.
2. getGameList: list its slots with id_hash, name, game_type, image and the demo flag.
3. createPlayer: open the player in GBP, EUR, SEK, ZAR or another native currency; it cannot change later.
4. getGame: request a launch URL with gameid (the id_hash), lang, currency, device, country and homeurl, then show it in an iframe.
5. getPlayerHistory: pull up to 500 rounds per call for support or audits, newest first, in UTC date ranges.

How the reel engines reach your wallet

Megaways cascades, Gigablox splits and DoubleMax multiplier chains all happen inside the game. What reaches you is simple: a debit for the spin, then a credit for the total win. During free spins, credits can arrive without their own debit, because the game pays the feature on its own. Where a Jelly title offers a bonus buy, it arrives as one larger debit.

Keep round_id on every leg, dedupe on call_id, reverse a debit once when you see rb=1, and never reject a call because of the type label. Reply HTTP 200 with error 0, 1 (insufficient balance, with the current balance) or 2. The signature is md5(timestamp + salt_key), checked within 30 seconds; the developer documentation has every field and a sample of each call.

Why take Jelly through an aggregator

Jelly is a strong mid-sized studio, and mid-sized studios are exactly where separate integrations stop making sense. With one game aggregator API, Jelly sits next to the studios whose mechanics it uses, on one wallet, with one set of reports.

Where Jelly games find their players

Jelly grew up in the UK and Scandinavia, and its catalogue has spread to Belgium, the Netherlands and Spain and, since 2026, to African markets. That matches our native currency list well: GBP, EUR, SEK, NOK, DKK and ZAR, plus CAD, AUD, NZD, BRL, MXN, INR and USD among others. For any currency outside that list, your account can run in USD or EUR while you convert on your side; send us a message and we will look at it together.

Players only see your casino brand, and every credential stays in your backend. You can review a white-label demo casino and a demo back-office before going live, and most operators are running in days. The catalogue evolves continuously, so check getGameList for the Jelly titles available now.
