About Razor Shark
Razor Shark launched on 20 August 2019 and became the game Push Gaming is defined by. It runs on a 5x4 grid with 20 fixed paylines, carries high volatility, and takes stakes from 0.10 EUR to 100 EUR. The theme is a dive into a kelp forest with sharks circling, but the reason it survived six years of releases is the maths, not the setting.
The RTP is the first thing to check, and it is the most important paragraph on this page. The headline figure is 96.70%. Since July 2021 Push Gaming has shipped Razor Shark in several configurations, and casinos choose which one to load: 95.05% and 90.52% are both in circulation, and Push Gaming's own game page also lists a 94.06% build. The gap between the top and bottom version is more than six percentage points — on a high volatility game that is an enormous difference in expected return, and nothing on the screen announces it. Open the paytable through the information button before your first spin. If the number shown is not 96.70%, the same game somewhere else will pay you back considerably more over time.
The paytable itself is tight. The great white shark is both the wild and the top symbol, paying 50x your stake for five on a line. Below it sit four shark variants: orange at 25x, purple at 20x, green at 7.5x and blue at 5x for five of a kind. The low tier is diving equipment — camera, mask, fins and tanks — each paying 2.5x for five. Those are modest line wins by modern standards, which tells you exactly where the money is: not in the base symbols, but in the features stacked on top of them.
Mystery Stacks are the engine. They land in stacks of four, then nudge down the reels and reveal themselves, either as a matching regular symbol filling the stack or as golden sharks. Golden sharks fire Razor Reveal, which converts the mystery positions into mini-reels awarding cash multipliers from 1x to 2,500x your stake, and scatters. Land three or more scatters and you enter the free games, where reels 2 and 4 are entirely filled with Mystery Stacks that nudge down one position per spin. Every nudge and reveal raises the running multiplier by +1, with no ceiling written into the maths. The round runs until the stacks fall off the reels — you start with a handful of spins and extend the feature every time fresh scatters or fresh stacks appear.
There is no bonus buy on Razor Shark, which in 2019 was normal and today makes it an outlier among high volatility releases. Push Gaming later built the sequel Razor Returns on the same engine, but the original remains the reference point.
