Razor Shark plays across 20 paylines; Jammin’ Jars fills an eight-by-eight grid with cascading fruit. Both are Push Gaming slots, but the way their wins build is quite different. Here you can compare the games, open demos and find UK casinos carrying the developer’s titles.

Push Gaming demos and mobile games
The demos below use virtual credits. They let you explore Push Gaming slot games without staking money, and demo winnings have no cash value. For adults aged 18 and over.
You have viewed 8 of 89 games!
In the Razor Shark demo, watch what happens when a stack of mystery symbols nudges down a reel. In Jammin’ Jars, follow a jar’s multiplier through the cascades. Those details explain the gameplay more clearly than a short run of wins or losses.
A phone screen gives the large Jammin’ Jars grid much less room. Try opening its paytable and finding the stake setting on your device. If either is awkward to read, check the other screen orientation before deciding whether the mobile layout suits you.
Our Push Gaming slot reviews
Our Razor Shark review covers the original game’s rules, features and RTP in more detail.
Razor Shark, Jammin’ Jars and Big Bamboo compared
Razor Shark centres on nudges, Jammin’ Jars on cascades and Big Bamboo on symbol reveals. The slot provider rates all three as high volatility, despite their different bonus features.
| Game | How the game develops | Feature to look at |
|---|---|---|
| Razor Shark | Five reels, four rows and 20 paylines | Nudging mystery stacks and Razor Reveal |
| Jammin’ Jars | An 8×8 grid with cascading wins | Wild jars carrying their own multipliers |
| Big Bamboo | Mystery symbols can reveal paying symbols or special symbols | Golden Bamboo reveals and collectors |
Razor Shark: follow the mystery stacks
A stack of four mystery symbols is the feature to watch in Razor Shark. It can nudge down the reel before revealing symbols. A Golden Shark can trigger Razor Reveal, where the mystery positions become small reels displaying prizes.
In free spins, reels two and four carry the mystery symbols. The feature also has an increasing win multiplier.
Jammin’ Jars: fruit clusters and wild jars
Jammin’ Jars uses cluster pays, with five or more matching symbols needed for a win. The winning fruit then disappears. New symbols drop into the empty spaces and can make another winning group, continuing the cascade.
Each wild jar carries its own multiplier. When it joins a winning group of fruit, that multiplier applies to the win. Follow the jars as the grid changes: their positions matter for the next cluster. Landing three or more jars triggers free spins.
Big Bamboo: what is inside the symbols?
In Big Bamboo, mystery symbols can turn into ordinary paying symbols, wilds or Golden Bamboo. The golden symbols lead into a reveal feature with prizes and modifiers, including collectors that gather revealed values.
Push Gaming’s published feature list also includes gamble options, so read the rules of the version you open rather than assuming every option shown in a video is available at your casino.
Fat Rabbit and Retro Tapes: two more feature styles
Fat Rabbit uses a five-by-five layout and 50 paylines. A rabbit and a wild carrot trigger free games, during which collected carrots make the rabbit grow and award extra spins.
Retro Tapes takes the cluster route. Its Wild Tape symbols carry multipliers, while a Magnet can pull matching symbols together. For slot players who enjoy following a changing game board, that is another mechanic to compare with the jars.
The Razor and Jammin’ Jars series
Push Gaming’s catalogue includes Razor Returns, Razor Ways and Razor Shark Jackpots alongside the original Razor Shark. Jammin’ Jars also has a separate sequel, Jammin’ Jars 2. The extra words and numbers identify different games, with their own rules; they are not simply alternative lobby labels.
For other studios and their game ranges, our casino game providers guide brings the supplier reviews together.
About Push Gaming
Push Gaming was founded in 2010, initially helping land-based suppliers bring games online. The developer turned to original slot development in 2015 and has offices in London and Malta.
Push Gaming became majority-owned by LeoVegas on 31 August 2023, when the MGM Resorts International subsidiary bought an 86% stake. MGM’s 2025 annual accounts put the total acquisition consideration at US$146 million. The accounts give a price for the deal; they do not tell us how much Push Gaming earns each year.
UKGC and Malta licences
You can find Push Gaming Holding Plc in the UK Gambling Commission register under account 54984. The entry covers remote gambling software and game host (casino) activities, with active licence number 054984-R-332139-012.
Push Gaming Malta Limited holds MGA/B2B/779/2020, a Malta Gaming Authority critical supply licence covering Type 1 gaming services. These are supplier licences. The online casino taking your deposit needs its own appropriate operating licence.
Push Gaming RTP and game versions
Push Gaming publishes more than one return-to-player setting for several titles. Its game pages list 96.70% and 94.06% for Razor Shark, 96.83% and 94.25% for Jammin’ Jars, and 96.13% and 94.13% for Big Bamboo.
That makes a single headline RTP an incomplete comparison. If a review gives the higher figure, the casino’s version may still use the lower setting. Look in the game’s information panel for the percentage attached to the version you are about to play.
RTP is calculated over a very large volume of play. A 96% figure does not mean a £100 session will leave you with £96. High volatility describes substantial variation in results, and a run of losing spins does not make a bonus round due. Set a spending limit before playing and stop when you reach it.
Finding Push Gaming casinos in the UK
Use the full title in the casino search. Searching only for “Razor” may bring back several games, and the original’s rules will not explain all of them. Check the mobile lobby too if that is where you intend to play.
For a casino bonus or free-spins offer, the eligible-games list matters. A promotion on one Push Gaming title does not necessarily cover the rest of the catalogue. Check its wagering requirements and any game restrictions before opting in.

Push Gaming questions
Does the LeoVegas acquisition make Push Gaming games exclusive to LeoVegas?
No. Push Gaming games are also listed by other operators, including Grosvenor’s UK casino. Ownership of the studio does not mean that every game is restricted to one casino group.
Why does a Push Gaming slot have a different RTP from the one in a review?
The game may be supplied with several RTP configurations. The number in the casino’s game information is the relevant one for that version; a review may describe another configuration. Matching the title alone does not confirm the percentage.
Is “highest observed win” the same as a slot’s maximum win?
No. An observed win records a result, whereas a maximum win describes a limit set by the game’s rules. Push Gaming uses the “highest observed win” label on some game pages. Read that label carefully before treating the number as a payout ceiling.
