Razor Shark Slot: RTP, Mystery Stacks and Free Games
Razor Shark plays like a standard 20-line slot until the Mystery Stacks land. These four-high blocks hide what’s underneath, and when they open you’ll see either ordinary paying symbols or a Golden Shark, which starts Razor Reveal and turns the stack into mini-reels with instant prizes.
Free Games build on the same idea. Reels 2 and 4 fill with Mystery symbols that nudge down one position every spin, and each nudge raises the multiplier. There’s more than one RTP version too.

How Razor Shark works
Razor Shark has five reels, four rows and 20 fixed paylines. Its Mystery Stacks can reveal ordinary paying symbols or a Golden Shark, which opens Razor Reveal.
In Free Games, the Mystery symbols nudge down reels 2 and 4, increasing a multiplier that applies to line wins and Razor Reveal instant awards.
What are the Mystery Stacks in Razor Shark?
Push Gaming describes the Mystery Stacks as four symbols high, able to appear anywhere on the reels. You see the covered positions first, then find out what the stack reveals.
They are Mystery symbols, not stacks of Wilds. Push Gaming’s game information confirms there are no stacked or expanding Wilds here. If a stack reveals a paying symbol, it simply counts towards line wins as normal. A Golden Shark is where things change.
How does Nudge & Reveal work?
Nudge & Reveal is what happens next: the stack shifts on the reel, then opens to show what’s underneath. The nudge only moves it; the reveal is what tells you what you’ve got.
Push Gaming doesn’t say exactly how far a stack moves in the base game, but in Free Games the rule is precise: Mystery symbols nudge down one position with every spin, and that movement drives the feature multiplier.
What is Razor Reveal?
When a Mystery position reveals a Golden Shark, Razor Reveal begins. The Mystery positions become mini-reels, which can show instant bet-multiplier awards or Scatter symbols.
Golden Shark: revealing this symbol from a Mystery position starts Razor Reveal.
Each instant award is worth between 1× and 2,500× your stake. That 2,500× is the biggest single award in Razor Reveal, not the most the game can pay.
How are Free Games triggered in Razor Shark?
Three or more Scatter symbols trigger Free Games, and you start with at least five Free Games.
Bonus / Scatter: the Bonus symbol works as the Scatter. Land three or more to trigger Free Games.
Extra triggering Scatters can award more spins and nudge the Mystery Stacks upwards before the feature starts. Push Gaming doesn’t say exactly how many extra spins each additional Scatter adds, so I haven’t guessed.
How do Mystery Stacks work in Free Games?
When Free Games begin, reels 2 and 4 fill with Mystery symbols. They nudge down by one position on every spin, so the positions keep moving through the feature rather than revealing just once.
More triggering Scatters can also give the stacks a higher starting position. That changes where the stacks start, but it doesn’t tell you anything about how later spins will go.
How does the Razor Shark Free Games multiplier work?
Every Mystery-symbol nudge increases the Free Games multiplier, and Push Gaming is specific about what it applies to: line wins and Razor Reveal instant awards.
So every nudge does two jobs: it moves the Mystery symbols down and it pushes the multiplier up. A bigger multiplier makes those wins worth more when they land, not more likely to land.
What is the RTP of Razor Shark?
There isn’t a single RTP figure that covers every Razor Shark configuration. Push Gaming’s public game page shows 96.70% and 94.06%, while its developer sheet lists six versions altogether.
| Current public page | 96.70% and 94.06% |
|---|---|
| Other documented configurations | 95.05%, 92.50% (UK-marked), 90.52% (Germany-marked) and 88.42% (Germany-marked) |
The 92.50% version is marked UK in the developer sheet. That tells you a UK version exists, not that every British casino uses it.
Razor Shark wasn’t one of the games in our UK casino RTP study, so I can’t tell you which version UK casinos are using. The game’s rules or info screen will show the RTP for the version in front of you.
Is Razor Shark high volatility?
Push Gaming describes Razor Shark as High volatility on its public page and in its game information. That’s Push Gaming’s label rather than something I’ve measured, and it won’t tell you how often the game pays or how a session will go.
What is the maximum win in Razor Shark?
I haven’t found a fixed maximum win in the Push Gaming material reviewed for this guide. What the developer has reported instead are observed results: about 55,000× the stake across billions of test spins, and later a player win of about 85,000×.
Those are results Push Gaming has reported, not a published maximum. The later player result exceeded the earlier testing record, so neither should be treated as a formal cap. The 2,500× award in Razor Reveal is a separate, feature-specific maximum.
Great Britain stakes and Feature Buy
Since 2025, the legal maximum stake per game cycle on online slots in Great Britain has been £5 for customers aged 25 or over and £2 for those aged 18 to 24. A casino or game client can set a lower limit.
Push Gaming’s documentation for the Razor Shark version reviewed here lists no Feature Buy or other optional game tools. Feature Buy availability can differ between games and jurisdictions, so this shouldn’t be taken as a rule for every Razor Shark-related product or market.
Release date and jackpots
Push Gaming’s launch article dates Razor Shark to 3 September 2019.
Push Gaming’s reviewed game information lists no jackpot tiers, and its developer sheet records no instant jackpots for this version.
Razor Shark FAQ
Is Razor Reveal’s 2,500× award Razor Shark’s maximum win?
No. It’s the top instant award in Razor Reveal. Push Gaming has separately reported wins of about 55,000× in testing and about 85,000× for a player, and neither is a fixed cap.
Does the UK-marked 92.50% RTP apply at every British casino?
No. It’s one of the versions on Push Gaming’s developer sheet. To see which version a casino is running, check the RTP in the game’s rules or info screen there.

Where this guide comes from
I’ve built this page from Push Gaming’s own game sheet, game information and published articles. Where the developer sheet lists more RTP versions than the public page, I’ve kept both, and I’ve kept the reported 55,000× and 85,000× wins as results rather than a cap.
