About game provider

Rat King review

Rat King transports players to a magical factory where rats have taken over.

Feisty white rats with royal ambition have started cooking up a variety of irresistible desserts. Players will sample cakes, donuts, and macarons, while trying to stay on the rodents’ good side.

Players who are in the mood for a lighthearted atmosphere will particularly appreciate this slot.

Graphics, Sounds and Animations

The cheerful beeps of the soundtrack bring to mind retro video games. Meanwhile, quirky percussion notes add tension, and chimes celebrate wins.


Rat King is a six-reel, six-row slot. Wins are awarded when players land 7 or more matching symbols anywhere on the reels.

Rat King - Cascade system
Game uses the Cascade System for wins

The Cascade feature means that clusters of matching symbols will disappear, making way for new symbols to fall into their positions.

The maximum win for this slot is 10,000x the player’s total bet.

Wilds, Bonuses and Free Spins

Dud symbols have no value and can be identified by their gray coloration. Whenever at least 7 matching Dud symbols appear anywhere on the reels, they will vanish, allowing new symbols to fall into the grid.

At the bottom of the reels, players will find Collection Boxes where Star symbols are gathered after they land in the bottom row. After entering the Collection Boxes, the Star symbols contribute their multipliers to that round.

Rat King symbols are also collected in the Collection Boxes whenever they land in the lowest row. This contributes to the Free Spins meter.

When at least 3 Rat King symbols are gathered in one round, the Free Spins feature begins. Players are awarded 3 additional free spins if a Rat King symbol is collected during the Free Spins feature.

Rat King paytable
Full paytable for the Rat King slot

With medium volatility, Rat King is a less ideal match for our preferred slot machine strategies. Our slot strategies target the highest possible volatility.


We recommend this high RTP, moderate volatility dessert and rat-themed slot.

With adorable retro imagery and unique bonuses, players will have no trouble staying engaged in the gameplay of Rat King.

Mathematically-inclined players will like the solid RTP, even if they are less enamored with the moderate volatility.
