Slots Like Rat King: Push Gaming’s First Pay-Anywhere Grid With a Carrying Multiplier
Rat King is a 6×6 pay-anywhere video slot from Push Gaming, released on 27 July 2023 as the studio’s first title built around a scatter-pays mechanic rather than fixed paylines. Wins land whenever 7 or more matching symbols appear anywhere across the 36-position grid, and each winning cluster cascades away to make room for new symbols falling in behind it. The default RTP sits at 96.30%, though operators can configure lower variants down to 88.19% and a boosted "Push Bet" tier reported at roughly 96.34-96.35%, so it pays to check the info screen on whichever site you load it from. Volatility is rated medium, stakes run from £0.10 to £100 a spin, and the headline draw is a persistent multiplier counter fed by falling star symbols that can push a single spin up to a 10,000x stake win. Anyone hunting slots like Rat King is really after that combination of a factory-set candy theme, cascading wins, and a multiplier that keeps building rather than resetting.
Where to Play
Rat King appears in the slot libraries of various UK-licensed online casinos rather than any single exclusive site, so availability and the exact RTP variant on offer will depend on which operator you choose. Gambling can be addictive; please play responsibly and only with licensed, UK-regulated operators. You must be 18 or over to gamble.
How the Game Works

The setting is a blacked-out confectionery factory rendered in chunky pixel art, all conveyor belts, forklifts and glowing candy pots lit by the odd flickering strip light. It’s a clear step away from the fruit-machine throwbacks Push Gaming built its name on, closer in spirit to a retro platformer than a traditional fruit slot, and the rat king himself lurks as the scatter symbol, crown askew, watching over his sugar-coated kingdom.
The reels move with a satisfying snap rather than a slow tumble, and the base game rarely sits still for long once a win chain gets going. Because the multiplier meter sits permanently on screen next to the grid, every spin carries a visible sense of progress even on quieter sessions, which keeps things engaging without the game needing to constantly throw big single wins your way.
It should suit players who liked the cascading, cluster-style mechanics Push Gaming used in Jammin Jars or Fat Santa but want a persistent multiplier layered on top rather than a counter that resets every spin. Anyone chasing huge, spiky max-win swings might find the medium volatility a bit tame by comparison, but for a steadier cascade-and-build session it’s a solid fit.
Symbols and Paytable
The paytable is built entirely from pixel-art sweets and factory imagery rather than playing cards, which fits the theme nicely. Lower-value symbols are individual sweets, cake slices, macarons, iced gems and striped lollies, and these need a cluster of at least 7 matching symbols anywhere on the grid to pay out, with bigger clusters worth more. Star Multiplier symbols sit outside the paytable proper; instead of paying directly, each one that lands drops into a collection box beneath its reel and adds its value, reported by aggregators to range from around 2x up to 500x, onto the running multiplier shown beside the grid. The Rat King himself is the scatter symbol and doesn’t feature in the regular paytable either, since his only job is triggering the Free Spins round.
Cascading Pay-Anywhere Wins
Rat King drops the fixed paylines most slots use in favour of a pay-anywhere system across its 6 reels and 6 rows. Land 7 or more of the same symbol anywhere on the grid and they pay out, then disappear to let new symbols cascade down from above, so a single spin can chain through several wins before the grid finally settles.
Star Multiplier Collection
Star symbols carrying a multiplier value fall into collection boxes at the foot of each reel rather than forming clusters themselves. Every star collected adds its value to a persistent counter that sits alongside the grid, and that counter keeps climbing rather than clearing between spins, which is what allows the bigger multiplier swings to build up over a session or a Free Spins round.
Free Spins and Retriggers
Landing 3, 4 or 5 Rat King scatter symbols in a single spin awards 10, 15 or 20 Free Spins respectively. The multiplier counter carries over into the round instead of resetting, so any value already banked in the base game keeps working for you. Collecting further Rat King symbols during Free Spins adds another 3 spins on top, so a well-timed retrigger can stretch the round out considerably.
Push Bet and Bonus Buy
A Push Bet option is available that increases the stake by 20% in exchange for better odds of triggering the Free Spins feature. Push Gaming also built in a Bonus Buy option, priced at 100x, 250x or 500x stake for direct entry into 10, 15 or 20 Free Spins, but UK-licensed operators aren’t permitted to offer bonus buy features under current Gambling Commission rules, so UK players won’t see this option regardless of which site they use.
Pros and Cons
- Persistent multiplier counter that carries through Free Spins instead of resetting
- Genuine pay-anywhere mechanic makes every spin feel active
- Distinctive pixel-art factory theme that stands out from Push Gaming’s usual fruit-slot style
- Free Spins retrigger keeps rounds going without needing fresh scatters from scratch
- 10,000x stake ceiling gives the multiplier build genuine upside
- Medium volatility means the multiplier can take a while to build to anything meaningful
- Bonus Buy is switched off for UK players, so the feature can only be reached organically
- Independent sources don’t fully agree on the exact Push Bet RTP figure, so it’s worth checking the in-game panel
- Lower-tier symbols pay modestly on their own without a multiplier boost

Demo Play
Most UK-licensed casinos that list Rat King let you try it in a free-play demo mode before switching to real stakes, usually accessible straight from the game’s lobby tile without needing to register an account. It’s a sensible way to get a feel for how the multiplier counter builds and how often the pay-anywhere clusters land before committing any real money.
Expert Take
What stands out about Rat King is how well the persistent multiplier fits the pay-anywhere format Push Gaming was trying out for the first time here. Rather than bolting a familiar bonus feature onto a new grid shape, the studio built the whole session around one steadily growing number, and that gives even quieter spins a reason to keep watching the reels. It won’t suit players who want frequent big single hits, since medium volatility keeps things fairly even, but as a slower-burn cascade slot with a clear sense of progression it’s one of the more interesting releases in Push Gaming’s back catalogue.

Our Verdict on Rat King
Rat King takes Push Gaming’s cascading-grid pedigree and adds a persistent multiplier that actually feels meaningful, since it survives from the base game into Free Spins rather than resetting on every new round. The pixel-art factory setting gives it a distinct identity that’s a world away from the studio’s earlier fruit-themed titles, and the pay-anywhere mechanic keeps the reels feeling active even during quieter stretches. Medium volatility means it won’t suit anyone chasing constant big single hits, but for players who enjoy watching a multiplier build steadily toward a genuine 10,000x ceiling, it’s a well-constructed and distinctive release.
