Some studios chase quantity. Push Gaming chases the perfect game. This small London outfit does not flood casinos with hundreds of titles a year. It drops a careful handful, and somehow two of them turned into slots so influential that the rest of the industry spent the next five years copying them. Fewer games, deeper dents.
The two culprits are a disco full of dancing jam jars and a slightly terrifying nudging shark. Jammin’ Jars made cluster-pays slots cool, and Razor Shark gave the world a mechanic every rival wanted a piece of. Neither looks like a slot that should reshape an industry, yet both did.
Here is what makes Push different from most big names in this hub. It did not build a licensing empire or a game-serving platform. It just makes brilliant, high-risk slots that streamers and serious players adore. Pure studio, no side hustle, and a cult following to show for it.
Provider type: Game Studio. Push Gaming builds its own video slots and that is the whole job. No live tables, no aggregation of other studios, no licensing programme. On our Provider Types filter it sits cleanly under Game Studio.
Who is Push Gaming, in plain English
A London studio since 2010
Push Gaming was founded in 2010 and works out of London and Malta, holding licences from both the UK Gambling Commission and the Malta Gaming Authority. For years it was a quiet name that hardcore slot fans whispered about while casual players had no idea who made their favourite games. A run of breakout hits changed that, and Push became one of the fastest-growing studios around.
The boutique approach
Push plays the quality-over-quantity game, and it plays it well. Rather than churn out endless filler, the studio ships a smaller catalogue built around sharp mechanics, distinctive themes, and unapologetically high volatility. Its games tend to look and feel a cut above, which is why they punch so far above the studio’s modest size. When a Push slot lands, people notice.
The two games that made Push famous
Jammin’ Jars, the disco that started a craze
Released in 2018, Jammin’ Jars is a kaleidoscopic disco set on an eight-by-eight grid where you win by forming clusters of matching fruit rather than lines. Sticky Wild Jars park themselves on the grid and grow a multiplier every time they help make a win, cascading reels chain wins together, and the Rainbow feature drops giant symbols into the mix. It was groovy, it was different, and it dragged cluster-pays slots into the mainstream conversation almost single-handedly. Fans still adore it years later.
Razor Shark and the Mystery Stack everyone copied
Then came the big one. Razor Shark arrived in 2019 and introduced Mystery Stacks, symbols that land face-down, nudge their way up the reels, and then flip to reveal paying symbols, wilds, or the Golden Shark that powers the bonus. In the free spins, a multiplier climbs and climbs, all the way toward a huge 2,500x, feeding a max win of 85,000 times your bet. The mechanic was so good that rival studios spent years building their own versions of it. Razor Shark is comfortably Push’s biggest game, and it still holds up.
Beyond the two big hits
The Fat series and the wider catalogue
Push is not a two-game studio, whatever its reputation suggests. The Fat series, including Fat Rabbit and Fat Banker, built a loyal following around bonus-buy gameplay. Big Bamboo turned a cheeky panda into a genuine hit, Wild Swarm sent a swarm of bees after big wins, and Mad Cars brought demolition-derby chaos to the reels. The studio also loves a sequel, and it keeps pushing its max wins higher.
Razor Returns currently tops the catalogue with a ceiling of 100,000 times your stake, while games like Bison Battle and Jammin’ Jars 2 sit at a still-eye-watering 50,000x. Elsewhere the catalogue happily roams, from the retro cassettes of Retro Tapes to the underground heat of Mount Magmas and the prehistoric stomp of Dinopolis, proof that Push will chase an odd idea whenever it fancies one rather than repeat a safe formula. The one constant is ambition on the numbers. Big potential is the house style.
The studio streamers cannot stop playing
Here is something money cannot easily buy: Push Gaming has a genuine fanbase. For a studio of its size, the level of devotion is unusual. Slot streamers and their audiences treat Razor Shark bonuses as event television, because the way the mechanic builds tension, with mystery symbols nudging into view one at a time, is made for a live crowd holding its breath. Big-win clips from Push games rack up huge numbers online, and new releases get picked apart and celebrated the way film fans dissect a director’s latest.
Part of it comes down to a recognisable Push feel. The sound design is sharp, the pacing is deliberate, and the payout structure rewards patience with the occasional jaw-dropping moment. Once you have played a few, you start to spot a Push game before you even see the logo. It also helps that Push resists flooding the market. When a studio releases only a handful of games a year, each one arrives as an event rather than background noise, and fans have time to actually learn and love them. Scarcity, done right, breeds loyalty, and Push has plenty of it.
The Push style
Mystery Stacks and cluster pays, explained simply
Two ideas define most Push games. The first is cluster pays, where wins come from groups of touching symbols instead of paylines, then cascade so one spin can pay several times, exactly as Jammin’ Jars does. The second is the Mystery Stack, a face-down block of symbols that reveals what is underneath only after it lands, sometimes nudging into place first. Both mechanics are built to create sudden, dramatic swings, which is precisely why Push slots feel so tense and so moreish.
Bonus buys and big risk
Many Push games, especially the Fat series, offer a feature buy that lets you pay upfront to jump straight into the bonus round. It is a fast track to the action and a fast way to spend, so approach with care, and note that some regulated markets do not allow bonus buys at all. Across the board these are high-volatility slots, designed for players who accept plenty of quiet spins in exchange for the chance of a monster hit.
Who owns Push Gaming
Push spent most of its life independent, but it now has serious backing. In 2023 it was acquired by LeoVegas Group, which is itself owned by the casino and resort giant MGM Resorts International. Crucially for fans, Push kept its own leadership and creative direction rather than being swallowed whole, so the games still feel like Push. Big parent, same studio soul.
What Push Gaming is like to play, and where
High risk, high reward
Push builds for the brave. Its slots run high volatility almost across the board, which in plain terms means long stretches where little happens, broken up by the occasional enormous payout. That profile made Push a darling of streamers and big-win hunters, who love filming the exact moment a Razor Shark bonus either fizzles or detonates. Thrilling on a good day, patience-testing on a bad one.
Mobile, fair and built with care
Every Push slot is built in HTML5 and runs smoothly on a phone with no app or download. The maths sits on tested random number generators, and the studio holds licences from strict regulators like the UK Gambling Commission and the MGA, so the odds you are shown are the odds you get. Fair does not mean easy, but it does mean honest.
How to spot it, and where to play
Spotting a Push game is easy once the classics are on your radar. Most casinos let you filter the lobby by provider, and even without the filter, Razor Shark, Jammin’ Jars, Big Bamboo and the Fat series are dead giveaways. You will find these titles at a wide range of licensed sites, including plenty of crypto casinos and newer brands that court the high-volatility crowd, often bundled with casino bonuses and free spins. Since a Push slot could in theory pay something enormous, it is worth checking a site’s payment methods and withdrawal limits first, and our top-rated casinos list is a solid place to begin.
A quick, honest word on risk
No sugar-coating it. High volatility means the dry spells are long and completely normal, and those 100,000x headlines are astronomically unlikely by design. Set a budget you are happy to lose, treat the top prize as a daydream, and Push stays a genuine thrill instead of an expensive habit.
Push Gaming in 2026
The studio is having a busy year. 2026 has already brought Big Bamboo 2, the retro-themed Retroverse, a fresh Wild Swarm, and Razor Shark Jackpots, which bolts a new jackpot round onto the famous formula after a couple of years away. Push has also been expanding into new regulated markets, going live in places like Alberta and pushing further into Italy, and it has even spun up a sister label, Reel Hot Games, to make simpler classic-style slots alongside its flagship releases.
The core identity has not budged, though. Push still makes fewer games than the factories, still leans into high risk and high reward, and still lands more genuine hits per release than studios many times its size. Backing from a giant has widened its reach without watering down the recipe.
The bottom line
Push Gaming is proof that you do not need a licensing empire to leave a mark. It made two of the most copied slots of the modern era in Jammin’ Jars and Razor Shark, built a devoted following on sheer quality, and kept its identity even after a giant came knocking. Its games are high-risk, high-reward and beautifully made, which makes them a must-try if you like your slots with real bite. You will find them across most of our best casinos and plenty of other online casinos too.
