While the name might sound a bit dark, Rat King is a volatile retro-themed slot by Push Gaming based on sweets. The slot runs on a Cluster Pays engine which means cascade after cascade paired with some fun features. On top of that, it has a removal feature and multipliers up to x100, which will bring you inches closer to the maximum 10,000x win.

What’s most impressive about this Push Gaming release is how retro it looks. It’s been done on purpose but matches any decades-old game in style. Push Gaming has done a great job with the visuals and the volatile math model, where you unlock greyed-out symbols to remove them from the grid and have new ones replace them in cascades. The Rat King can devour the sweets and unlock the bonus round, giving way to new special features that can take your wins to the top.

If you’re looking for a slot that’ll bring back Nintendo vibes, Rat King is the perfect 8-bit retro trip.

The Rat King online slot plays out on a 6x6 Cluster Pays grid. More specifically, the slot runs on the Pay Anywhere system with at least seven symbols in a cluster paying prizes. The more you pop, the better the returns. Visually, the slot’s inspired by retro games we played on Nintendo and similar consoles as kids. Push Gaming did the 8-bit visual style justice with cool animations and a pixelated art style that makes everything look amazing.

Of course, the video is paired with matching audio, making it even more of a time machine. It’s a blast from the past that no one expected, but here it is in all its glory.

The Rat King mobile casino slot runs great across Android and iOS devices. Be it a smartphone or a tablet, you can easily fire it up from a browser and play it on the go.

Playing the Rat King slot is not hard work. Push Gaming’s retro bonanza has a pretty familiar layout that’s easy to read. In short, you adjust your bet first and hit the big Spin button on the right. As a Cluster Pays slot game, you get paid by popping seven or more symbols in a cluster which triggers a cascade and repeats itself as long as there are winnings symbols on the grid.

Besides the colorful sweets, you’ll also see greyed-out symbols on the grid. Gamers know that these can be unlocked in some way. In the Rat King slot, they’re called Duds. They have no value and can be removed from the reels when a total of seven matches are on the reels. This will clear the grid off them and make way for new symbols to drop on the grid.

At the bottom of the grid, you’ll see special collection boxes. When a star symbol lands on the bottom position, it is collected in one of the boxes. Once it is, the multiplier displayed in the box is applied to your total win. The Rat King symbol is collected in these boxes when it lands on the bottommost position, adding an increment to the multiplier.

Besides being collected to raise the multiplier values, the Rat King symbol is also a scatter. When three or more are collected, you’ll receive ten free spins. Four or five Rat Kings will deliver 15 and 20 free spins. In the bonus round, three additional scatters will provide three extra spins.

When the star multiplier symbol is collected, its multiplier is added to the counter and boosts any win. The multiplier will then be inactive until another multiplier is added to the counter.

Besides this, the free spins round plays just like the base game. It can be pretty lucrative thanks to the multipliers, and this is also the spot where the slot reaches its apex.

Push Gaming has set the Rat King slot RTP to a solid 96.3% for a medium volatile title. The maximum projected win is 10,000x the bet and can be hit in the bonus round.

Rat King is a pixelated spinning bonanza that we rarely get to see these days. It’s a slot that brings back memories of simpler times when running games on your platform or PC didn’t cost several thousand dollars. While retro in style, it has modern features starting with the Cluster Pays mechanic, which can deliver decent wins your way. A few surprises are also added to the mix, making it a great summer hit available at legit online casinos.
