Razor Shark — Kinghills

Razor Shark is a 5x4, 20-line slot from Push Gaming, released in 2019. RTP is 96.70% or 94.06% depending on the casino's version, volatility is high, and the big money sits in the free games, where the multiplier keeps rising.

Push Gaming is one of the studios in the Kinghills slot lobby, alongside Pragmatic Play, Play'n GO, Hacksaw and Nolimit City. The quickest way to Razor Shark is the search bar: type "razor" and you will usually see the whole family, including the sequel Razor Returns. Filtering by provider works too if you want to browse Push Gaming's other titles, such as Jammin' Jars or Fat Rabbit.

The game plays the same on mobile. Kinghills runs in the browser rather than through an app store download, and Razor Shark scales well to a phone in portrait. See our mobile page for how to add the site to your home screen, and the games section for the rest of the lobby.

One thing to check before you spin: the game's info screen. It shows the RTP version this casino runs. We explain below why that number is worth thirty seconds of your time.

On the surface it is a standard 20-line video slot. You pick a stake, spin, and three or more matching symbols from the left on a payline pay out. The low-paying symbols are card royals; the higher ones are sea creatures, with the shark at the top.

What makes it different is the seaweed. Mystery Stacks are four-high columns of seaweed that can land on any reel. When one lands, it triggers Nudge and Reveal: the stack slides down one position at a time and opens up, turning into a matching symbol for a win, or into golden sharks that start the Razor Reveal. In the base game this is where most of your mid-sized wins come from.

Honestly, the base game can be quiet. Long runs of small or no wins are normal on a high-volatility slot, and you shouldn't read anything into them. The game is built around a feature that can pay a lot and doesn't arrive often.

Push Gaming's own page for the game doesn't state a single maximum. What we can say for sure is that each Razor Reveal coin pays between 1x and 2,500x your bet, and the free games multiplier has no fixed ceiling. Review sites often quote 50,000x as the headline figure.

Treat that as the edge of what is possible, not a target. At a £1 stake, even a 500x hit (£500) is a great session, and most players will never see four figures from this game. Pick your stake by what you can afford to lose, not by the size of a max win you are very unlikely to reach.

Push Gaming lists two RTP versions of Razor Shark, and the casino picks one. The difference sounds small, but over a few hours of play it adds up.

The lower version costs you close to double on average for the same play. That is why we tell people to open the info screen before playing any Push Gaming slot, at any casino. If it shows 94.06%, you might prefer a different game with a higher configured RTP.

Volatility is high. In practice that means a small number of large wins make up most of the payout, and the balance can drop steadily between them. With a £50 budget, a £1 stake gives you far fewer chances to see the feature than 20p does. Our tips section has more on sizing stakes.

A demo is the best way to learn how the Mystery Stacks behave before you put money in. At Kinghills, look for a Demo button on the game tile; whether it appears depends on the game, your region and whether you are logged in. If there isn't one for Razor Shark, the Push Gaming game page describes the features in detail.

Keep one thing in mind: demo credits feel free, and people bet bigger in demo than they would with cash. Play the demo at the stake you would actually use. At UK-licensed casinos, by law, you can't open a demo at all until your age has been verified.

Razor Shark is the same game wherever you play it, but the rules around it are not. Here is how Kinghills compares with four big UK-licensed brands.

Whether a particular brand carries Razor Shark, and in which RTP version, changes over time, so check the lobby. The rules in the table don't change from game to game. More on what the Curaçao licence means is on our licence page.
