Push Gaming publishes this as the game's default RTP. Studios ship several RTP builds of most titles and whoever serves the game picks the version, so
we cannot promise this demo or any casino lobby runs this build. Read the RTP in the game's info panel
wherever you play for real.
Push Gaming's own page lists two builds, 96.70% and 94.06%, and states that RTP may vary per casino, so casinos choose which build to run.
Razor Shark is the 2019 Push Gaming original that built the studio’s reputation for savage volatility: a 5x4, 20-payline dive where Mystery Stacks nudge down to reveal Golden Sharks, and a free-spins multiplier climbs toward a max win widely reported at 50,000x bet. Most sessions grind, a few detonate - one 2020 hit was even reported to have beaten the stated maximum at roughly 85,000x. The demo is where you find out what that volatility actually feels like before any real money is involved.
How the game works
A 5x4 grid with 20 paylines, paying left to right. The engine is the Mystery Stack: stacks of four mystery symbols that can land anywhere on the reels and trigger the Nudge and Reveal feature - the stack nudges down one position per spin, opening up to show either regular paying symbols or Golden Sharks.
Mystery Stacks and the Razor Reveal
Golden Sharks trigger the Razor Reveal: each Golden Shark position turns into a mini-reel that awards an instant prize from 1x up to 2,500x bet, or a scatter symbol. Land three or more scatters - naturally or through the reveal - and the free games begin.
Inside the bonus, reels 2 and 4 fill with Mystery Stacks that nudge down one position per spin, and a win multiplier applied to every win climbs with each nudge - reviewers report +1x per step, an extra spin for each additional trigger scatter, and the round running until the stacks drop out of view. The combination of stacked reveals and a compounding multiplier is what produces the reported 50,000x-class results, and they are correspondingly rare - this is a patience game where the bonus does all the heavy lifting.
Razor Shark or Razor Returns?
If you got here searching for “razor shark returns”, those are two different games. Razor Shark (2019) is the original: 5x4, 20 lines, default 96.70% RTP, max win widely reported at 50,000x. Razor Returns (2023) is the sequel that doubles the frame: 5x5, 40 lines, a 100,000x ceiling, scatter-scaled starting multipliers, and an optional Push Bet that raises the free-spins trigger rate without changing the RTP of its default build. The quiet surprise is the math: the original’s default build still returns more, though only narrowly - Push publishes 96.70% for Razor Shark against 96.55% for the sequel, and the Push Bet does not close that gap. The sequel trades a sliver of RTP for a doubled ceiling and a more elaborate bonus; volatility is brutal either way. Pick Razor Shark for the leaner original, Razor Returns for the bigger engine.
RTP honesty check
Push Gaming’s own game page lists two builds: 96.70% (default) and 94.06%, and states plainly that RTP may vary per casino. Aggregators report additional reduced versions - around 95.05% and as low as roughly 90.5%. On a game this volatile, a shaved RTP compounds hard over the long dry stretches, so check the info panel or loading screen where you play; our RTP guide shows exactly what to look for.
The bottom line
Razor Shark remains the reference point for Push Gaming’s high-volatility style: one clean mechanic, a bonus that carries all the potential, and long quiet runs between the moments that matter. Learn the nudge rhythm here with play money and treat the widely reported 50,000x as a mathematical curiosity, not a plan - and if the style clicks, our Jammin’ Jars demo and Big Bamboo demo cover Push Gaming’s other cult hits.
When you are ready for real bets, choose the casino by its payout record rather than its bonus size - our honest casino reviews rank sites on exactly that.
