Push Gaming Slots & Where to Play in the UK

By Jack Henshaw, Head Writer · Published 4 July 2026 · Last updated 9 July 2026

Push Gaming is the London studio that made “players first” a maths policy rather than a slogan: creator of Jammin’ Jars, Razor Shark and Big Bamboo, HTML5 pioneers since 2010, and now part of the LeoVegas/MGM family with its founders still at the wheel. Fewer games than its rivals; a higher hit-rate than almost any of them. Our verdict: 8.5/10. This Push Gaming review covers the best Push Gaming slots ranked, the famously generous maths examined, and the licence file.

The best Push Gaming slots: 10 games that actually matter

Ninety games, ten places — and an unusually easy shortlist, because Push’s hits are genuinely canonical. RTPs quoted are headline defaults; the paytable check applies here as everywhere. The full ranked catalogue is near the end of the page.

1. Jammin’ Jars (2018)

The disco fruit that built the house: an 8×8 cluster grid where three wild jars boogie across the board, each carrying a multiplier that grows with every win it touches — and when two jars join the same cluster, their multipliers combine and the room loses its mind. A 96.83% published default (extraordinary for maths this wild), a 20,000x ceiling, and a permanent place in every “greatest slots ever” argument worth having. Eight years on, still the best advert for the entire cluster genre.

2. Razor Shark (2019)

The mystery-stack legend. Seaweed columns conceal either a wall of matching symbols or — the dream — Razor Reveals that spit out coin values and multiply the entire nudging sequence. Its published default sits around 96.7%, its recorded community peaks reach as high as a filmed 85,000x-class win (see biggest wins), and its grip on streamer culture rivals anything from Hacksaw or Nolimit. The sequel Razor Returns and 2024’s Razor Ways keep the feeding frenzy going.

3. Fat Santa (2018)

The Christmas slot that refused to stay seasonal: Santa eats mince pies, grows to cover up to a 5×5 area of the grid, and waddles wild across the reels while the snow falls. It founded the entire “Fat” dynasty (Rabbit, Drac, Banker, Mama and friends) and remains a genuine January-to-December staple in UK lobbies — proof that one perfect sight gag, mathematically weaponised, outlasts any theme calendar. Published default around 96.5%.

4. Big Bamboo (2022)

The modern flagship — and the face of the studio’s own homepage. A serene panda presides over golden-coin collections, feature symbols and free spins whose multiplier ladders climb toward a documented 50,000x ceiling — the catalogue’s biggest number until its own March 2026 sequel, Big Bamboo 2, pushed it to 75,000x. It gave Push a second all-timer for the volatility era without abandoning the house warmth, and its bamboo-snapping bonus entry is among the most satisfying sounds in modern slots. Published default around 96.1%.

5. Mystery Museum (2019)

Razor Shark’s occult sibling: the same beloved mystery-stack engine relocated to a haunted museum, where full-height artefact stacks reveal matching symbols and the free spins hoard their secrets. Many connoisseurs quietly rate it above the shark — moodier, tighter, with a published default around 96.6% — and its lantern-lit aesthetic has aged beautifully. The catalogue’s great underrated heavyweight.

6. Wild Swarm (2018)

The beehive that taught slots patience: every wild landed feeds the hive, and five progressive levels of swarm modes await those who keep it fed — a persistence mechanic years ahead of its time, plus a hidden button players still swear improves their luck (it doesn’t; they press it anyway). The 2023 sequel confirmed what the faithful knew: the swarm was one of the great designs of its generation. Published default around 96.5%.

7. Fire Hopper (2022)

The grasshopper with a lighter: cluster wins burn away, the hopper leaps between multiplier zones, and the fire spreads across the grid in chains that feel genuinely combustible. It arrived in the Big Bamboo vintage and cemented the studio’s modern cluster language — brighter than Jammin’ Jars, meaner underneath, with a five-figure ceiling and a published default around 96.5%. A community staple from day one.

8. Retro Tapes (2022)

Synthwave nostalgia on an expanding grid: wins stretch the reels taller, neon rails multiply the clusters, and the whole thing plays like a mixtape from an arcade that never existed. Alongside Retro Sweets, it’s the studio’s designers at their most stylish — and the maths crowd noted the generous published default (around 96.7%) with approval. The catalogue’s coolest deep cut gone mainstream.

9. Dinopolis (2021)

Dinosaurs running a city, a dino-coin currency, and Trex Bonus spins where sticky multiplier dinos stomp toward five-figure paydays — Dinopolis is Push’s sense of humour given a skyline. Beneath the Flintstones energy sits one of the studio’s sharpest volatile models (published default around 96.4%), and its cult following among streamers has never thinned. Joyful on the surface, jurassic underneath.

10. Jammin’ Jars 2 (2021)

The sequel that dared touch the sacred: same dancing jars, plus a Giga Jar loot-crate meter that banks spins toward an enhanced free-spins mode, and a ceiling raised to a documented 50,000x. Purists still argue original-versus-sequel like it’s a band’s discography — which is, of course, the point: no other studio’s fanbase debates its games this way. Published default around 96.4%.

Push Gaming vs the studios it competes with

Push sits in the volatility cohort but plays a different game — generosity as strategy. Against our previously reviewed studios:

The honest read: Hacksaw out-brands it, Play’n GO out-ships it, Nolimit out-extremes it — and Push out-pays them all at the published-default level, which is exactly the reputation it set out to buy with fifteen years of “players first”. The catalogue is the smallest on this table and the affection-per-game the highest. There are worse trades.

The game families, in depth

For a ninety-game catalogue, Push runs a remarkable number of true franchises. The full ranked list covers the rest.

The Jammin’ dynasty

Jammin’ Jars (2018) → Jammin’ Jars 2 (2021) → the wider disco of Jammin’ Jars-adjacent cluster designs that shaped Fire Hopper and Candy Blast. The dancing wilds with trailing multipliers remain the studio’s signature image — and the community’s original-versus-sequel debate remains its longest-running show.

The Fat family

Fat Santa (2018) → Fat Rabbit → Fat Drac (2021) → Fat Banker (2022) → Fat Mama’s Wheel and beyond — one expanding-character gag, endlessly reinvented: each instalment feeds its glutton toward grid-filling wild status. It’s the most commercially dependable franchise in the building and the clearest expression of the house’s comic warmth.

The mystery-stack line

Razor Shark (2019) → Mystery Museum (2019) → Razor Returns (2022) → Razor Ways (2024) — the engine that made “what’s under the stack?” a genre question. Fully-stacked reveals chaining into coin symbols remain among the most-clipped moments in slots, and the shark itself is the studio’s unofficial mascot.

The hive and the hopper

Wild Swarm (2018) → Wild Swarm 2 (2023) → Wild Swarm Triple Hive (2025) → Wild Swarm 3 Chocolate Eggs (2026), plus spiritual cousins Fire Hopper and Bison Battle — the persistence-and-progression wing, where meters, levels and collected states reward players who stay. Triple Hive introduced a 3 Pots system that Chocolate Eggs simply reskinned for Easter, and Push was building progression into slots years before the industry made it a buzzword.

The 2025–26 expansion

The newest structural move: Push Originals and Push Actions as formal categories, plus the Reel Hot Games classic-style sub-brand (September 2025) — the boutique diversifying into product lines without surrendering the quality gate. Masked Mayhem (October 2025) launched the Actions line; Candy Blast (March 2025) and the festive pair (10 Santa’s Reindeers, Santa Hopper) filled out the year. Into 2026, the flagships themselves got sequels: Big Bamboo 2 (March) raised the catalogue’s ceiling to 75,000x, RetroVerse (April) extended the Retro Tapes/Retro Sweets line with a Mystery Wilds and Light Gun mechanic, and Jiggy’s Pot O’ Gold (July) tried something rarer still — a genuinely low-volatility Push release.

Signature mechanics & technology

Push’s toolkit is small, polished and endlessly recombined — the boutique approach applied to maths design:

Wandering wilds with trailing multipliers

The Jammin’ Jars patent-in-spirit: wilds that move each cascade, growing +1 multiplier per win they participate in, and combining when they cluster together. The maths consequence is a compounding tail — most spins are quiet, but jars converging on a big cluster produce the four-figure moments the game is famous for.

Mystery stacks

Full-reel stacks that reveal as one symbol — or as coin-paying specials (Razor Reveals, museum artefacts). It’s variance origami: hit frequency stays readable while the reveal distribution hides a monstrous right tail. The engine behind both Razor Shark’s legend and Mystery Museum’s cult.

Expanding characters

The Fat family’s trick: a character symbol that grows with each feed (pies, carrots, blood bags, banknotes) until it occupies a 5×5 wild block. Mechanically it’s an escalating wild-area bonus; theatrically it’s the best running joke in slots.

Persistence meters

Wild Swarm’s hive levels, Big Bamboo’s coin collections, Jammin’ Jars 2’s Giga Jar: state that survives between spins and matures into enhanced modes. Push builds waiting into the design — and makes the waiting legible, which is why its progression features feel rewarding rather than manipulative.

Bonus Boost™ and the UK reality

Instead of (banned-in-the-UK) bonus buys, Push’s house option is Bonus Boost: pay a premium per spin (typically ~25–50% more) to multiply bonus-trigger frequency, fully available to British players. It’s the most UK-friendly feature-acceleration design in the industry — a genuine differentiator nobody else’s reviews bother to flag.

HTML5 heritage

Push built for HTML5 from 2010 — before the iPhone had settled the argument — and the engine’s crispness still shows: instant loads, immaculate scaling, animation timing that rivals video games. The “players first” slogan started as an engineering standard before it became a maths one.

Push Gaming slots RTP: the real numbers

The defaults: the most generous headline set among the volatility studios — Jammin’ Jars at 96.83%, Retro Tapes and Razor Shark in the high 96s, the modern flagships mid-96s. Push made above-average published RTP a brand promise years ago and has largely kept it, which the sharper end of the community has always respected.

The builds: and here’s the honest asterisk — reduced-RTP configurations of Push games circulate too, casino-selected, exactly as we document for NetEnt, Pragmatic and everyone else. A Jammin’ Jars at 94% exists in the wild, and the whole point of the 96.83% headline evaporates if your casino picked it. Ten seconds in the paytable settles it; make them a habit.

Volatility and ceilings: high across the board — the clusters and mystery stacks carry long quiet stretches and violent tails, with documented ceilings of 20,000x (Jammin’ Jars), 50,000x (Big Bamboo, Jammin’ Jars 2) and, as of March 2026, 75,000x (Big Bamboo 2), and Razor Shark’s filmed community peaks reaching the 85,000x class. Bonus Boost raises trigger frequency, not expected value. Stake for the droughts, and keep our responsible gambling guide within reach.

From land-based ports to the MGM family

The arc that matters: fifteen years, two founders, one identity — through bootstrap, breakout and a Vegas-giant acquisition that conspicuously changed nothing visible. In an industry where studio character rarely survives its exit, Push’s continuity is the story.

The people who built Push Gaming

James Marshall — co-founder & CEO

Marshall has run Push since the bootstrapped beginning — through the porting years, the pivot to originals, the Jammin’ Jars breakout and the MGM-era acquisition, after which he simply… kept running it. His public through-line has never wavered: quality over quantity, published maths players can trust, and a release only when it’s ready. Fifteen years of the same sermon, with the catalogue as the receipts.

Winston Lee — co-founder & COO

The operations half of the founding pair, Lee built the studio machinery that lets a boutique ship at flagship quality — and stayed COO through the same acquisition that usually scatters founding teams. Together the pair represent something genuinely rare on these pages: an intact founding duo, still in post, sixteen years in.

The LeoVegas/MGM chapter

The 2023 majority sale to LeoVegas Group — itself owned by MGM Resorts International — put one of Vegas’s giant names quietly behind the boutique. The deal’s visible effect has been distribution muscle and nothing else: same founders, same cadence, same maths philosophy. As acquisitions in this industry go, it’s the rare one the players didn’t notice — which is presumably the compliment MGM paid for.

Is Push Gaming fair? Licensing, regulation & the record

Checked against the Gambling Commission’s business licence register on 4 July 2026.

The licences. Push Gaming Holding Ltd holds UKGC account 54984 with active remote gambling software and game-host (casino) licences since January 2020 — the successor to Push Gaming Ltd’s original licence (account 38366), held from October 2014 until the 2020 corporate restructure. That’s over a decade of continuous UK regulation. Verify both entities on the UKGC public register. Distribution beyond Britain runs on a Malta Gaming Authority Critical Gaming Supply Licence (MGA/B2B/779/2020) plus registrations with Ontario’s AGCO and Romania’s ONJN, confirmed live on Push Gaming’s own site, with independent lab certification throughout.

The record. Clean: no UKGC enforcement action, penalty or licence review against either Push entity that we can find, across twelve years of British operation — and the MGM-family acquisition added a parent with its own formidable compliance obligations. Boutique scale, blue-chip paperwork.

So is it fair? Yes — and unusually, fairness is the brand: certified RNG everywhere it operates, published RTPs that lead its class, hit rates in the info screens, and a UK-legal Bonus Boost instead of workarounds. The standing caveats are the industry’s, not Push’s alone: reduced builds circulate (read the paytable), and generous published maths is still volatile maths — the tails on these games demand respect and modest stakes.

The biggest Push Gaming wins

Fixed maths, no jackpot network — the records are multiplier events, and the community has filmed some beauties. Documented ceilings and recorded events only:

On tape: a Jammin’ Jars single hit for the ages, and the Razor Shark session that entered community legend:

Videos embedded for illustration — results shown are the players’ own, and the seaweed usually hides seaweed.

Beyond the reels

The corners of the Push story the ranking competitors never reach:

The generosity gambit

Push’s founding commercial bet was genuinely contrarian: publish higher RTPs than the market, accept thinner margins, and let the sharpest players evangelise the brand. It worked — the maths community’s trust in Push is unlike anything its rivals enjoy — and the bet’s slow erosion (reduced builds circulating; newer flagships publishing mid-96s rather than JJ’s 96.83%) is watched by that community like a canary in a coal mine. So far, the canary sings.

The hidden button

Wild Swarm ships with a secret: tap the sleeping bear (players found it within days) and the game acknowledges you. It changes nothing mathematically — and the community has pressed it religiously for eight years anyway. No detail better captures Push’s relationship with its players: little jokes left where only the devoted will find them.

The porting-house prehistory

The vault here isn’t retired games — it’s the first business entirely: years spent converting other companies’ land-based cabinets to HTML5, learning cabinet-grade polish and mobile discipline before ever shipping an original. When Jammin’ Jars arrived looking impossibly finished for a small studio, that was the apprenticeship showing.

Vegas money, London manners

Push is now the only UK-founded studio in our tier-one list majority-owned by a Las Vegas resort giant — MGM, via LeoVegas — and simultaneously the tier-one studio whose culture has visibly changed least. The three-line 2025 expansion (Originals, Actions, Reel Hot Games) is the first structural evidence of scale ambition; the quality gate, so far, has travelled with it.

New Push Gaming slots: what’s launched for 2025–26

The state of Push right now: the boutique is diversifying — three product lines, a broader release slate, and the house franchises still anchoring the front page. 2026 has been a numbered-sequel year in particular: Big Bamboo 2 and the Wild Swarm hive’s latest acts prove the flagships still get first call on the roadmap, even as Viva Lock Vegas queues up as the next one out the door. This section refreshes with every significant launch.

All ship with published figures — and with builds selected casino-side. Paytable first, always.

What players actually say

From the forums and streamer chats where Push enjoys an unusually warm seat — our words, cons intact.

The love: trust, mostly — rare and hard-earned. The published maths lead the class and the community knows it; the games feel finished in a way volume studios can’t match; and the personality (dancing jars, fat Santas, hidden bears) earns affection rather than mere attention. Jammin’ Jars and Razor Shark are spoken of as classics without embarrassment, and Bonus Boost gets singled out — correctly — as the UK’s fairest feature-acceleration option.

The gripes, plainly: the output is slow, and between flagships the faithful get restless — “one great game a year” is the affectionate-but-pointed version. The volatility punishes casual bankrolls despite the friendly art, which catches newcomers off guard. Some fear the 2025 three-line expansion is the beginning of volume-chasing, and the drift of newer defaults below the JJ-era highs gets tracked with suspicion. And Razor Shark’s seaweed, the community wishes it known, is usually just seaweed. All fair; the trust survives.

Our verdict on Push Gaming

Slot Providers score: 8.5/10 — the boutique that kept its promises: class-leading published maths, franchise-grade hits, and a character no acquisition has dented.

Push suits maths-conscious players, cluster and progression fans, UK players wanting legal feature-acceleration, and anyone who’d trade release volume for release quality. Look elsewhere if you need constant novelty — Play’n GO and Pragmatic run the firehoses — or gentler variance, where NetEnt’s classics remain the kind option; for Megaways-scale ceilings, Big Time Gaming wrote the rulebook. And whatever you open: confirm the build in the paytable, because 96.83% is only yours if your casino chose it.

Every Push Gaming slot that matters, ranked

From a catalogue of roughly 90 titles, here are the 50 that matter, ranked by all-time greatness — craft, influence, maths and staying power blended. (NEW) marks 2025–26 releases. Re-ranked as the boutique ships.

Ranked 4 July 2026, refreshed 9 July 2026, from a catalogue of just over 90 titles. Availability and RTP build vary by casino — the fast-rotating Reel Hot shelf is summarised rather than itemised. Asterisked entries (Big Bamboo 2, the Wild Swarm hive’s newest two acts, RetroVerse, Jiggy’s Pot O’ Gold) are ranked here on spec and lineage alone — each is too new for the independent play-testing our top-10 write-ups require, so their fuller detail lives in the new releases section rather than the numbered top-10 above.

Push Gaming FAQs

Who owns Push Gaming?

LeoVegas Group — part of MGM Resorts International — holds a majority stake following the deal announced in 2023. Push operates independently, and co-founders James Marshall (CEO) and Winston Lee (COO) remain in charge, as they have since 2010.

Is Push Gaming fair, or are its games rigged?

Push has made fairness its brand: certified RNG in every regulated market, class-leading published RTPs (Jammin’ Jars at 96.83%), hit rates in the info screens, and over a decade of UK licensing (currently account 54984) without enforcement action. Reduced builds circulate as at every studio — the paytable states yours.

What is the best Push Gaming slot?

Jammin’ Jars is the all-time classic; Razor Shark is the streamer legend; Big Bamboo is the modern flagship, though its own 2026 sequel Big Bamboo 2 has since taken the catalogue’s biggest-ceiling crown. Our full ranked ten, with reasoning, is above.

What RTP is Jammin’ Jars?

The headline build publishes 96.83% — among the most generous defaults of any high-volatility slot — but reduced builds exist and casinos choose per game. The in-game paytable shows the figure you’re actually playing.

What is the biggest Push Gaming win?

The catalogue’s largest documented ceiling is now 75,000x on Big Bamboo 2 (2026), ahead of the 50,000x shared by the original Big Bamboo and Jammin’ Jars 2; the most famous filmed result is still a Razor Shark session in the 85,000x class from a €5 stake — preserved on video in our wins section.

What is Bonus Boost?

Push’s feature-acceleration option: pay a premium per spin to multiply your bonus-trigger frequency. Unlike bonus buys, it’s legal for UK players — making Push one of the few volatility studios whose acceleration feature works in Britain.

What is the Fat family?

Push’s expanding-character franchise: Fat Santa (2018), Fat Rabbit, Fat Drac, Fat Banker and Fat Mama’s Wheel, each starring a glutton who grows into a grid-covering wild. It’s the studio’s most dependable comic property.

How many games has Push Gaming made?

Around 90 — deliberately the smallest tier-one catalogue, released at roughly one a month, with the 2025 restructure adding the Push Originals, Push Actions and Reel Hot Games lines.

What are the newest Push Gaming slots?

The 2026 wave has been sequel-heavy: Big Bamboo 2 (March, 75,000x ceiling), Wild Swarm 3 Chocolate Eggs (March), RetroVerse (April) and the low-volatility Jiggy’s Pot O’ Gold (July), with Viva Lock Vegas queued for network release on 22 July 2026. 2025 brought Candy Blast, Masked Mayhem (launching the Actions line), the Reel Hot Games sub-brand and the festive pair 10 Santa’s Reindeers and Santa Hopper. Full slate in our new releases section.

Did Push Gaming really start by porting land-based slots?

Yes — from 2010 the bootstrapped studio converted land-based cabinets to HTML5 before pivoting to original games mid-decade. That apprenticeship in cabinet-grade polish is why its first originals arrived looking so finished.

Where can I play Push Gaming slots in the UK?

Push’s own family casino, LeoVegas, carries the fullest UK shelf, and the flagships turn up widely elsewhere too — Videoslots, Casumo, bet365, PlayOJO, 888casino and William Hill among them. Our UKGC casinos section lists the confirmed carriers; always verify any operator on the Gambling Commission register before depositing.
