How to play Rat King mobile slot

The Rat King slot has a retro style that is cute and bubbly, but this candy factory hides a maximum win of 10,000x your bet if you can catch enough rats and enough multipliers.

The Rat King mobile slot is set on a 6×6 grid and brings you only 6 candy-shaped paying symbols. If that’s the treat, what’s the trick? Those 6 symbols also come as dud greyed-out characters that don’t pay.

Match any 7 symbols anywhere on the screen (paying or dud), and those symbols will explode, leaving space for more symbols and (hopefully) more wins. This is a grid slot in the most traditional and best way.

You have little boxes at the bottom of the reel where you’ll try to capture the rat king scatter or the juicy star multiplier. The Rat King triggers free spins with sticky multipliers, and the multiplier symbol, you guessed it, multiplies.

The Rat King slot grid has few surprises

And that’s ok. You don’t have to be surprised when you play video slots; you must be entertained and feel like you could win big.

Well, good news, this Rat King slot machine has a top win of 10,000x your bet thanks to those multiplier symbols. You might get a 2x or 4x multiplier in the base game on your win, which will tide you over.

It’s not easy getting those multipliers to the bottom of the screen and into those boxes. Meanwhile, when playing on a tablet casino, you are left spinning a fairly mediocre paytable and some very small retro-looking graphics.

The Rat King slot free spins save the day

In the free spins, when a multiplier hits the bottom of the reel, it gets saved up in the top right-hand corner. Once saved, it will be applied to the next symbol win.

Then it turns inactive. But don’t worry, get another multiplier, and it gets added to the right-hand box and goes active again for the next win.

This is good fun, especially when the multiplier is active and the tumbles are frequent. It’s less fun if you only have 10 free spins, and the multiplier is more set on grey than green.

All these active and inactive symbols kill the anticipation a bit, making it unlikely that we will return to this Rat King game often. But, at its core, it’s a decent grid slot with a big top win and a big multiplier. If you like the genre, you’ll find it at your favourite online casinos.

Bonus Features

Win all Ways and Avalanching Wins: When seven or more characters are anywhere on the screen, you get a win. Those wins explode, and more symbols tumble from above. This continues until no more wins can be found.

Dud Symbol: When the normal symbols are in grey, they have no value. But if you find 7 or more of the same kind, and they will also explode - you don't get a win, but you clear space for more symbols to avalanche down.

Collection Boxes: A box sits below each reel at the bottom of the grid. The Star symbols are collected in the boxes if they reach the bottom of the reel. This is a multiplier that will be added together to all wins.

The boxes can also collect the Rat King symbol. In one avalanching win, 3 symbols will trigger 10 free spins, 4 will trigger 15 free spins, and 5 scatters will trigger 20 free spins.

The Free Spins Bonus: You get free spins by collecting Rat King in the bonus boxes below. The main difference between the base game and the bonus game is in the multiplier.

Every time a multiplier is collected, it will be applied to the next win. It will then go inactive, but when a new multiplier symbol is collected, it will be added to the old one, increasing the multiplier amount each time.

However, the multiplier can only be applied to one win.

Push Bet: This increases the RTP of the Rat King slot game from 96.30% to 96.34%, and your odds of getting a bonus in those boxes.

Buy Bonus: You can buy entry into the free spins anytime.

Rat King Review Conclusion

The Rat King slot on mobile is not a real money game we would have played back in the dawn of video slots, but we could see ourselves taking the occasional spin here.

It's a shame that the multipliers in the free spins are so restrictive. It kills the build-up of excitement when you have only a few spins to try and capture so many multipliers for a single win.

And yet the multipliers are there. The RTP is a healthy 96.34% and the top win of 10,000x your bet. It's a hard one to fault, and a decent addition to ourPush Gaming slots list.
