Rat King (Push Gaming) – Review & Demo Play

Rat King: Slot Overview

Rat King is Push Gaming's first pay-anywhere Scatter Pays slot, set on a 6x6 grid where at least seven matching symbols anywhere in view will pay. Wins and batches of seven or more Dud symbols trigger cascades, opening space for fresh drops. Stakes range from 0.10 to 100 per spin, and there is an optional Push Bet that raises the stake by twenty percent for better bonus odds. With medium volatility and a top prize of 10,000x, it sits squarely in my sweet spot.

Theme and Presentation in Rat King

Rat King runs full retro with chunky pixel sweets, a black and blue chequered grid framed by pipes, and punchy bleepy effects that scream late nineties arcades. The factory backdrop sells the night shift vibe, while the 8-bit icons keep the screen readable during busy cascades. The soundtrack leans on synth lines and crisp taps, so even long sessions feel like a lost cartridge on an ageing telly. It is a style that clicked with me straight away and kept the spins flowing.

Symbols and Payouts in Rat King

Rat King sticks to six regular paying sweets, from blue cookies and doughnuts through ice creams, yellow cakes and pink cakes, up to a red jelly dessert. Scatter Pays means 7 or 8 of a kind returns 0.5x to 2x the bet depending on the symbol, while 20 or more matching sweets pay between 7.5x and 50x. Everything pays anywhere on the grid, and winning collections are removed, which lets the tumble chain push totals higher on the same stake.

Grey Dud symbols carry no value, yet seven or more of the same type clear in one go, and I have seen whole batches vanish to open lanes for multipliers. Star symbols land with values from x2 up to x500, and they must drop to the bottom to be caught by a Collection Box and added to the round's win multiplier. The Rat King symbol is the scatter for the meter, and it is collected the same way.

Bonus Features in Rat King

Every win triggers a cascade, removing paying symbols and dropping new ones from above. Dud clears also trigger a redrop when seven or more of the same grey icon land. Below each reel sits a Collection Box. When a Star multiplier reaches the bottom, it is collected and its value adds to the current spin multiplier. In the base game that total applies to the spin you are on, then resets before the next, so timing and drop order matter.

The bonus round arrives when 3, 4, or 5 Rat Kings are collected in one cascading sequence, awarding 10, 15, or 20 free spins. During free spins, each collected Rat King adds three extra spins. The global win multiplier does not reset for the duration, but it only activates on spins where a fresh Star is collected, which adds a nice layer of pace to the feature. When the board lines up, the tally can jump hard late in the round.

Push Bet costs twenty percent extra and lifts the chance of triggering free spins, with a small RTP rise to about 96.35. If allowed, Bonus Buy comes in three tiers, priced at 100x for 10 spins, 250x for 15 spins, or 500x for 20 spins, each starting with the respective number of Rat Kings. Those buys carry RTP figures in the mid ninety six range. The buy feature is not offered in the UK, which fits the rules I play under.

How to Win at Rat King Slot

Winning in Rat King is all about Scatter Pays on that compact 6x6. I aim for steady cascades, then work the grid to drag Stars and Rat Kings into the Collection Boxes. Seven or more matching basics anywhere starts things off, then clears can snowball. The sweet spot for me is when a Star tumbles late and lands in the box to activate a stacked total in free spins. With stakes from 0.10 to 100, I can scale sessions to suit my roll.

Rat King Slot RTP and Volatility

By default Rat King runs at 96.3 percent RTP on the base setting, with several lower configurations also shipped, including 95.24, 94.32, 90.21, and 88.19 percent. Push Bet raises the stake by twenty percent and nudges the figure to roughly 96.35 on the standard build, while wins are still calculated on the original bet. The maths sits in medium volatility territory, which I rate as a fair balance for this feature set.

On paper the slot can pay up to 10,000x the stake. The headline hit arrives on average once in about 11.2 million spins without Push Bet, and around 8.3 million with it active, so the outliers are rare yet not fantasy. In my sessions I have had plenty of bonuses land in the mid range, with the odd spike when the multiplier is live and a long cascade finally drops a late Star into a waiting box.
