Push Gaming slots on mobile are high-volatility titles such as Jammin’ Jars, Razor Shark and Big Bamboo, built by a London studio now majority-owned by LeoVegas Group. Most carry default RTPs around 96.1% to 96.8%, but several also exist in lower versions. This guide covers the studio, its mechanics, the real cost per hour and the UK rules in apps.
Push Gaming was founded in 2010, is based in London and holds a Gambling Commission licence (account 054984).
Its best-known slots are Jammin’ Jars, Razor Shark and Big Bamboo, and most of its catalogue we cover is rated high volatility.
Big Bamboo, Fat Santa, Fat Banker and Retro Tapes all come in lower-RTP versions, so check the help screen in your app.
At the fastest legal pace, 10p spins on a 96.13% slot cost about £5.57 an hour on average.
UK stake limits of £5 (25 and over) and £2 (18–24) apply to every Push Gaming slot in a casino app.

Who makes Push Gaming slots, and who owns the studio?
Push Gaming is a London-based slot studio founded in 2010, with a second office in Ta’ Xbiex, Malta. James Marshall co-founded the studio. In May 2023 LeoVegas Group announced a majority stake, which places the studio inside MGM Resorts, the group LeoVegas belongs to.
The studio supplies games to licensed operators rather than running its own casino, so you only ever play its slots inside a casino app or website. For British players the important detail is the licence: Push Gaming Holding Limited holds Gambling Commission account 054984. It is also licensed in Malta, Ontario and Romania.

Push Gaming slots on mobile: RTP, volatility and max win
The table lists every Push Gaming title in our slot database, using each game’s default or highest published RTP. A dash means the figure isn’t published in the specifications we hold, so check the game’s help screen in your app before you play.
Two patterns stand out. Seven of the ten titles are rated high volatility, and the newer games carry far bigger maximum wins than the 2018 Fat series. A big top prize usually means most of the return is held back for rare outcomes, so long dry spells are normal. The budget section below shows what that means for a small balance.
Push Gaming’s signature mechanics, explained
Push Gaming reuses a handful of ideas across its catalogue. Knowing them makes the paytables quicker to read on a small screen.
Moving multiplier wilds in Jammin’ Jars
Jammin’ Jars pays for groups of five or more touching symbols on an 8x8 grid, a format known as cluster pays. Winning symbols drop away, and the jam jar wilds hop to a new spot after each win, adding +1 to their multiplier whenever they join a winning cluster. Three or more jars start 6 free spins, and the jar multipliers carry into the round and can only rise. The sequel adds a DJ meter filled by gold vinyls, which can trigger the Giga Jar feature.
Nudge and Reveal in Razor Shark
Razor Shark drops stacks of four Mystery symbols that slide down one row at a time. Each nudge reveals either matching symbols or a golden shark, and the shark turns into coins showing multipliers or scatters. In the free games, reels 2 and 4 fill with Mystery stacks and a win multiplier climbs every time Nudge and Reveal fires, until the stacks leave the reels.
Growing wilds in the Fat series
Fat Rabbit and Fat Santa share a design. A wild character lands with a food symbol (a carrot or a mince pie) to start 5 free games, then moves around eating that food. Each meal helps it grow from 1x1 up to 5x5, and every size step adds extra spins. Fat Banker swaps the meal for Wild Money Bags and a meter that makes the Banker bigger.
Mystery Bamboo in Big Bamboo
Big Bamboo’s stacked Mystery Bamboo symbols all turn into the same random symbol, or into Golden Bamboo, where each position spins for an instant prize, a collector, a multiplier or a scatter. A gamble scatter decides how many free spins you get and how many low symbols become Mystery Bamboo during the round.
Why one Push Gaming slot can carry two different RTPs
Several Push Gaming games are offered to operators in more than one RTP version. The game looks and plays the same, but the long-run return is lower. It’s the operator’s choice, not the device’s, so an app and a website from the same casino normally run the same version. Our page on whether RTP is lower in casino apps explains why.

What Push Gaming slots on mobile cost per hour
UK rules mean an online slot spin must take at least 2.5 seconds, so the fastest possible pace is 1,440 spins an hour. Real play is slower, because free spins, cascades and reveals take time, so treat these numbers as a ceiling rather than a forecast.

On a high-volatility game the average hides a wide spread. A £20 balance at 10p gives 200 spins if nothing comes back, 40 spins at 50p and 20 at £1. At £1 a stake, a few dead spins can end the session before a bonus lands, which is why lower stakes stretch a fixed budget further.
Playing Push Gaming slots on your phone
Push Gaming games run inside the casino’s own app or mobile site, not as separate downloads, so the app you choose decides the login, payments and limits. The studio does not publish device requirements of its own; the casino app’s store listing sets the minimum iOS version. Our guides to casino apps on iPhone and on Android phones cover those details.
Grid games need room. The 8x8 Jammin’ Jars grid and the 54-position Retro Tapes grid pack many small symbols onto the screen, so a larger phone or a tablet makes clusters easier to follow.
Use Wi-Fi for long sessions. Slots download their graphics when they load, so a stable connection reduces the chance of a stalled spin.
Check your history after a dropout. UK technical standards cover interrupted games, so if your signal drops, reopen the game or check your account history to see how the spin ended.
Set limits first. A deposit limit set before you play is easier to stick to than one set mid-session.
How to find Push Gaming games in a UK casino app
Our partner apps don’t publish a full list of studios, so the only reliable check is the app itself. These steps suit most UK casino apps, though filter names differ.
Download the casino app from the App Store or Google Play and finish age and identity checks.
Set a deposit limit when the app prompts you before your first deposit.
Open the slots lobby and type a title, such as Razor Shark, into the search bar.
If the lobby has a provider filter, look for Push Gaming in the list.
Open the game, tap the help icon and note the RTP shown.
Choose a stake that fits your budget, staying within the UK stake limit for your age.
If nothing comes up, that operator may not carry the game. Our best slot apps UK ranking compares the slot lobbies of our partner apps.
No autoplay, and no turbo or slam-stop, under the game design rules in force since 31 October 2021.
Each spin takes at least 2.5 seconds.
Wins equal to or lower than your stake can’t be celebrated with sounds or animations.
Since a Gambling Commission warning in January 2020, feature buy-ins are not offered to British players, so you reach the bonus rounds only by landing them.
From 17 January 2025 you can’t play several games at once, and your net spend and time played must be shown in real time.
If you enjoy the cluster grids and moving wilds, Hacksaw Gaming slots use a similar mix of multipliers and big maximum wins. For something even more volatile, Nolimit City builds games around xWays and xNudge. Relax Gaming is another studio with a high-volatility focus. Each of these pages lists the RTPs we hold, so you can compare like for like.
Alternatives with a welcome offer for Push Gaming fans
We don’t have an offer linked to Push Gaming, and none of these welcome offers names one of its slots. They are slot offers on selected games, useful as a way to try a partner app’s lobby. 18+ and terms apply to all three.
PlayOJO: a first deposit of £10 or more gets 80 free spins on Big Bass Bonanza at 10p each, with no wagering, so winnings are paid as cash. New UK customers only, Northern Ireland excluded, and only through the designated offer link.

Frequently asked questions
Who owns Push Gaming?
LeoVegas Group owns a majority of Push Gaming, after a deal announced in May 2023. LeoVegas is part of MGM Resorts, so the studio now sits inside a much larger group. Push Gaming itself is still based in London, with an office in Malta, and James Marshall is one of its co-founders. The ownership change didn’t alter how its games reach you: they still run inside licensed casino apps. See our slot providers hub for other studios and their owners.
Can I play Push Gaming slots on my phone?
Yes, you can play Push Gaming slots on a phone through any UK casino app or mobile site that carries them. The studio doesn’t offer its own real-money app, so you need an account with a licensed operator. Search the slots lobby for a title such as Jammin’ Jars, and check the help screen for the RTP. Our best slot apps UK list explains how to pick an app with a strong slot lobby.
Is Push Gaming licensed in the UK?
Yes, Push Gaming is licensed by the Gambling Commission under account 054984, held by Push Gaming Holding Limited. That licence covers supplying games to British operators. The studio also holds a Malta Gaming Authority licence (MGA/B2B/779/2020) and approvals in Ontario and Romania. The casino app you play in needs its own Commission licence too. Our Coral Casino app review shows how an operator’s licence details look.
What is the RTP of Push Gaming slots?
Push Gaming slots we cover have default RTPs between about 96.1% and 96.83%, with Jammin’ Jars the highest at 96.83%. Several games also exist in lower versions, such as Big Bamboo at 94.13% and Fat Santa at 94.15%. On £100 staked, the gap between 96.13% and 94.13% is £2 of expected loss. The casino chooses the version, so read the game’s help screen. Our RTP glossary entry explains the figure in plain terms.
Are Push Gaming slots high volatility?
Most are: seven of the ten Push Gaming slots we cover are rated high volatility, including Jammin’ Jars, Razor Shark and Big Bamboo. Mount Magmas is medium and Fat Santa is medium to high. High volatility means long runs of small or no wins, with the return concentrated in rarer, bigger results. That suits a budget you are prepared to lose in full. Our page on what volatility means in a slot app has examples.
What is the biggest win on a Push Gaming slot?
The highest maximum win we hold for a Push Gaming slot is 100,000x stake on Razor Returns, followed by 50,000x on Big Bamboo and Jammin’ Jars 2. These are game caps, not likely outcomes, and reaching them is extremely rare. With UK stake limits, the cap is also bounded by your maximum spin of £5 or £2. Our Big Bamboo review explains how its Golden Bamboo feature builds toward the top prizes.
Can I buy the bonus on Push Gaming slots in the UK?
No, you can’t buy the bonus round on Push Gaming slots in a UK app. Since a Gambling Commission warning in January 2020, feature buy-ins are not offered to British players, so free spins and features are reached only through normal play. Some games keep in-bonus choices, such as Big Bamboo’s gamble scatter, and gamble features are not banned. The game design rules page lists the other limits on slot features.
Which Push Gaming slot should I try first on mobile?
There’s no best Push Gaming slot, but Mount Magmas is the only medium-volatility title we cover, with a 96.5% RTP, so it gives a steadier ride than the others. If you prefer bigger swings, Jammin’ Jars has the highest RTP in the range at 96.83%. Try any game in demo mode first where the app offers it, which still needs age verification. Read our Jammin’ Jars review and demo mode guide.
