You should agree that the classic or Egyptian gameplay is a bit boring, that's why we were so happy with the plot of Rat King by Push Gaming. This slot has 8-bit graphics, as well as a great and stylish soundtrack. In the story, we will get to the production where they make various sweets, but be more vigilant when you collect sweets as a rat is operating in the production. But there is also a positive in this since you can catch 3+ rats to get bonus free spins. We definitely give this story a rating of 10.

Bonus Rounds & Free Spins

In the Rat King slot by Push Gaming, gamblers will enjoy cascading mechanics and the paying anywhere system, which is very cool. The game also has an interesting system for activating multipliers and free spins. Below, we’ll write more about it, and we have already rated these bonuses as 8 out of 10.

Collection Boxes

In both the base and the bonus games, you will have a special box under each reel to collect bonus symbols. In order to activate the multiplier or free spins, you need to collect these symbols in these cells. With the help of the cascading technique, bonus symbols will drop down and this will help you get the bonus.

Star Symbols Multipliers

As we said above, in order to activate the multiplier, you need to lower the special symbol into the lowest cell. In the base game, the resulting multiplier will reset if you run out of winning combos, but in the bonus game, they will only accumulate. As a result, multipliers from 2x to 500x will be available.

Free Spins Feature

When you collect 3, 4, or 5 Scatters into cells, you will receive 10, 15, or 20 free spins, respectively. In the bonus game, you will have a chance to activate a re-trigger in the same way of collecting, but only for 1 Scatter, you will be entitled to +3 FS. It is worth noting that you can collect the required number of Scatters using the cascade technique.

This is what I understand what real hardcore is! It was a very bold decision to create such bonus mechanics. To get free spins, you need not only to collect Scatters but also to remove cascades so that the Scatters land on the very bottom of the reel. Same story with multipliers. I played for €0.10 per spin and it was very difficult to catch a worthwhile win. I was lucky to open rounds with spins twice, but there, I got €4.78 (47.8x) and €3.61 (36.10x). The result is so-so, but I'll be back!
