Rat King Slot Overview

The infamous rat king is one of nature’s phenomena that will either impress you or make you gag. It all boils down to your personal tolerance to rodents. Fortunately, in the Rat King casino slot by Push Gaming, you won’t witness nature’s cruelty but a funky 8-bit slot game with plenty of interesting features to boot.

Theme and Graphics

Get ready to be transported to a pixelated land filled with vibrant colours and nostalgic charm. Rat King is an animal-themed slot set in a dimly lit factory or warehouse, tiles underfoot, and the scent of aged cheese lingering in the air. 

As mentioned previously, the game features the popular 8-bit design we already saw in the Banana Town Dream Drop and Hellcatraz series, making Rat King a brilliantly designed slot that evokes the spirit of vintage Nintendo games with a soundtrack to match.

How to Play

Here's a quick look at the controls of Rat King: 

  • Before playing the Rat King game, open the menu (three horizontal lines) to read the rules and learn about the bonuses. 
  • Click the coin icon and decide how much you wish to bet per spin;
  • The spin button is the main button. Press the icon with two pointers to spin the reels;
  • To turn off the sound effects, press the speaker button.

How to Win

One of the best assets of the Rat King slot is the scatter pays mechanism. Forget all about the paylines and clusters because, in this game, it all boils down to landing matching symbols anywhere on the board.

And how many? The Rat King must pay as long as there are at least 7 symbols of a kind in view.

The betting limits for Rat King are between 10p and £1 per spin.

However, there’s a twist as this game features not only paying symbols but dud (non-paying) symbols and special symbols as well. Sweet treats may pay up to 50x the stake, while dud symbols don’t do anything but waste space!

In the Rat King slot machine, it is not only the toothy emperor who gets to feast! You will get an abundance of great bonus features to spice things up a bit. The most prominent feature is scatter pays, triggered each time you land at least 7 symbols.

Free Spins

Who doesn’t like a good free spins bonus round? Before you get all hyped up, understand that in this game, it takes more than a few scatters to trigger it. This is how it goes.

Each time a Rat King symbol manages to reach the bottom of the grid, it lands in the Collection Box:

  • 3 Rat symbols bring 10 free spins;
  • 4 Rat symbols fetch 15 free spins;
  • 5 Rat symbols reward 20 free spins.

Rat King symbols may also land during the bonus round. When they reach the bottom and end up in the box, they bring an additional 3 free spins each. The star symbol may also land, and when it does, you'll notice that it carries a multiplier.

Collection Boxes and Stars

And what are these boxes and stars, you might wonder? No worries, we’ve got you covered.

Star symbols are special symbols with multipliers. Each star may have a multiplier between x2 and x500. Once the Star ends up in the box, its value is added to the multiplier counter and then applied to the win.

Below every reel, there is a Collection Box. This is where the Stars and Rat Kings land.


There are plenty of great things about Rat King. The collect feature elevates this game beyond similar titles like Napoleon vs Rabbits or Banana Town, and its free spins feature is also quite entertaining. The game really brings something new and interesting to the online slots market.
