On July 27, Push Gaming, a B2B gaming supplier based in London, UK, launched Rat King, a rat-themed retro slot, featuring dessert-loving rats, especially one rat who called himself the “King of Sweets.” In addition, the provider’s previous hits include: Crystal Catcher, 10 Swords and Razor Returns.

Extraordinary visual:

True to its name, the main theme of the slot is the aforementioned “King of Sweets,” the rest of the rats and a lot of pastries. The game takes place in a pastry factory, where players can see a variety of delicious desserts landing on the reels. In addition, the game is made with a 32-bit design that is known for its memorable melodies and can be played on any device.

To win, players must form a combination of 7 or more matching symbols anywhere on the reels on a dynamic 6×6 grid as the scatter mechanism is applied.

The basic low-value symbols are cakes in purple, orange, pink, yellow, turquoise and red, which are worth between 7,5x to 50x a player’s bet for a combination of 20 or more. However, these symbols may also appear in grey and are then Dud Symbols with no current value, where when 7 of the them appear on the grid an the same time, they are removed, allowing new ones to take their places on the grid. Among the symbols there are also Star symbols equipped with different multipliers and the Rat King symbol as the game’s Scatter.

The game has medium volatility, a default RTP of 96.30% and a maximum win of 10,000x a player’s bet.

Slot features:

Casacade – when players make a winning combination, this feature is triggered. As soon as it’s activated, winning symbols disappear and new symbols drop to take their positions on the grid. In addition, it lasts as long as new winning combinations are made.

Collection Boxes – under the main reels, there are collection boxes placed, where Star symbols and Rat King symbols are accumulated when they appear in the bottom position. Therefore, when a Star symbol is collected, its multiplier will be added to the total winnings multiplier for that current spin.

Additionally, when Rat King symbols are collected, they are added to the free spins meter, which triggers Free Spins when minimum 3 of them are collected throughout the current spin.

Star Symbol – as already mentioned, when the Star symbol is collected in the collection box, its multiplier will be added to the total win multiplier. However, this total win multiplier will be applied to winnings made throughout the current spin in the base game, while the multiplier is constant in the Free Spins feature.

The Star symbol may appear with multipliers of x2, x3, x5, x7, x10, x25, x50, x100, x250 and x500.

Free Spins – when 3, 4 or 5 Rat King Scatters land on any reel, they reward 10, 15 or 20 free spins, individually, and the feature is triggered. Once triggered, players will get 3 additional free spins for each Rat King symbol accumulated throughout the bonus game. Also, if players accumulate Star symbols, they will have the opportunity to use the total win multiplier. However, this multiplier becomes inactive until a new multiplier is added to it.

Push Bet – this feature is triggered if players pay an additional 20% of their bet size. Activation automatically improves the chances of triggering free spins. However, winnings are then based on the original bet, and when this one is triggered the RTP rises slightly to 96.34%.

Bonus Buy – in order to trigger this feature, the player should want to get to the Free Spins immediately. The available options are:

100x – Free Spins activation with 3 Scatters giving 10 free spins. RTP is 96.58%;

250x – Free Spins activation with 4 Scatters giving 15 free spins. RTP is 96.63%;

500x – Free Spins activation with 5 Scatters giving 20 free spins. RTP is 96.93%.

Commenting on the launch, Amit Samji Principal Game Producer at Push Gaming, said: “Rat King is our very first pay-anywhere title. It also benefits from an inventive collection mechanic which is a testament to the incredible creativity our development team is blessed with. This imaginative feature is juxtaposed by a familiar retro style that together has produced a slot which we are confident players will adore.”
