Rat King Online Slot Review

The Rat King online slot is a food-themed game where a white rodent helps you to gather wins. It’s a desktop and mobile slot from Push Gaming that has a charming retro style, with blocky symbols across the 6 reels and 6 rows.

Cakes, doughnuts, and jellies pay in any places, with winning symbols removed from the grid and new ones dropping down. Multiplier symbols can boost prize values and there’s a free spins feature where the multipliers increase throughout.

It’s a medium volatility game and taken as a long-term calculation, the return to players is 96.34%. Let the valuable vermin loose at the best online casinos and you can win as much as 10,000x the stake from the Rat King slot machine.

How to Play the Rat King Online Slot

The deliberately old-fashioned graphics look good on PCs, Android, iOS, or Windows platforms. This 90’s arcade style sees pixellated snacks of various colors and flavours that also appear as greyed-out ‘Dud’ versions. Other symbols on the 6x6 grid include the round, red-eyed Rat King himself and stars that hold multiplier values.

They sit in a dark blue industrial setting, surrounded by forklift trucks and doughnut-making vats, accompanied by a suitably retro soundtrack. 

You can pick from a bet range of 0.10 to 100.00 per spin via a tap on the coins icon next to the reels. A Push Bet option costs 20% more but improves the odds of entry to the free games round by 39%, so it’s worth considering. You can also buy right into the free spins and also have access to fastplay and automatic spin options.

The 3 lines at the top of game unlock a paytable. The Rat King online slot pays a prize when you land at least 7 examples of the same active symbol, in any places. The red jelly is the most valuable, and it’s worth 2x the stake for 7-8 examples, increasing to 50x for 20 or more in view at once.

Free Spins & Other Features of the Rat King Slot Machine

Winning symbols trigger cascades as they vanish, and the symbols above drop down. New ones drop in from the top of the game and this repeats for as long as you have any new wins.

The Dud symbols have no value and just get in the way, but if you see at least 7 Duds on a spin, they also vanish which brings in new symbols via cascades.

Colorful star multiplier symbols hold values of up to 500x and don’t get removed. If a star reaches the bottom row, it collects in boxes below the reels. All star multipliers build in a meter at the top until a non-winning spin ends the cascades and the total value then applies to all wins from the sequence.

The Rat King also collects over the course of cascades. If 3, 4, or 5 reach the bottom row, you get 10, 15, or 20 free spins respectively, although they only start once any cascades come to an end. Each time the Rat King collects during the bonus games, he adds 3 extra spins to the total. 

During the free spins, star multiplier values build as before and apply to wins over any series of cascades. The multiplier then becomes inactive but remains in the meter, reactivating if a new star reaches the bottom row and adds its value. You can build a big multiplier this way, as it never resets for the duration of the free spins.

Our Rat King Slot Rating

The retro graphics have a certain charm but might not be to all tastes. However, the Rat King slot is one that everyone should try, as it comes with some up-to-date gameplay and features. The cascades with multipliers can run for a while, although 2x or 3x values are way more likely than 100x, 200x, or more. They can still build to a decent level over the course of cascades.

Once the free spins begin the multipliers can hit some serious amounts, potentially returning wins of 10,000x your total stake. Meet this royal rodent as you play the Rat King slot machine at our recommended desktop sites and casino apps that carry the Push Gaming range. 


The Rat King slot uses a scatter pays system. You win a prize when at least 7 matched symbols land on the 6x6 grid, and they can be in any places. Winning symbols vanish and new ones drop from above, which can lead to further wins.

Retro-style symbols feature in the Rat King slot. A food theme brings sandwiches, jelly, ice creams, and doughnuts to the reels, with blocky pixellated graphics across the board. Bonus symbols include stars and the Rat King himself.

Any star multipliers that reach the bottom row via a cascading symbols mechanism build in a meter. Their values climb until the end of the sequence, and the overall multiplier then applies to all wins. This feature of the Rat King slot can lead to big payouts from any spin.

The Rat King slot also has a free spins bonus round. You get 10, 15, or 20 free spins from 3, 4, or 5 rats, and during this round multiplier values don’t reset at the end of cascades. Any new multipliers add to the meter, and it’s here that you are most likely to win the maximum 10,000x prize.

Yes, it is. You can play the Rat King slot on iPhones, iPads, as well as phones and tablets running the Android or Windows operating systems. Some of the controls are repositioned for easy reach, but otherwise the desktop and mobile versions are identical.

The return to players percentage of the Rat King slot is 96.34%. That means for every 100.00 wagered on the game it pays 96.34 in prize money, but due to the medium level of volatility this is likely to vary widely as you play.

You’ll find the Rat King slot at our approved online casinos. We only recommend sites with the best games, excellent bonuses, wide range of deposit and withdrawal options, and the security of a full online gambling license from recognised jurisdictions.

The Rat King slot is similar to popular games such as Snack Time from Section 8 Studios, Hellcatraz from Relax Gaming, and Pixel Fruits 2D by Five Men Games.
