Rat Royale

By Zena Grantham | Updated 22 October 2026

Rat Royale is a medieval fantasy-themed video slot from Pragmatic Play, released on 22 October 2026. Deep beneath the streets, the rats have finally seized the throne, and they’re certainly not interested in sharing their newfound wealth. Forget noble knights and charming princes; this underground kingdom belongs to a rather sinister collection of rodents with expensive tastes and questionable intentions.

With four Rat Kings competing for control, a royal treasury worth raiding and a maximum win of 15,000x the stake, Rat Royale proves that even the most unwelcome residents can develop a taste for the finer things in life.

Technical Details

Rat Royale features a 5-reel, 5-row grid with 259 ways to win. Winning combinations require at least three matching symbols on consecutive reels, starting from the left. Stakes range from £0.20 per spin, with a maximum of £240 available in international markets. UK players face lower limits: £2 per spin for those aged 18–24 and £5 for players aged 25 and over.

The default Return to Player (RTP) is 96.52%, with alternative versions at 95.50% and 94.53%. With a hit frequency of 24.39%, winning combinations occur about once every 4.1 spins. Pragmatic Play has rated Rat Royale as medium volatility, suggesting a more balanced mix of smaller and larger payouts than highly volatile slots.

The maximum win is 15,000x the stake, though the odds of hitting it are about 1 in 55.2 million spins. Rat Royale is compatible with desktop, smartphone, and tablet devices, including Android and iOS, with no additional download required.

Design

A Rat King sits proudly on his throne in a gloomy underground lair, surrounded by gold and treasure that would make even the wealthiest of monarchs jealous. With an elaborate crown, golden jewellery, and a sceptre topped with a skull, this formidable rodent looks every inch the ruthless ruler of his subterranean kingdom. The scene has something distinctly reminiscent of Game of Thrones, though the royal court has clearly suffered a rather unfortunate infestation.

Pragmatic Play has created an impressive medieval fantasy theme, with towering Gothic arches, weathered stone pillars and cobwebs reaching across the shadowy chamber. Scattered skulls, skeletal remains and heaps of golden coins add to the atmosphere, while pale light filtering through the ruined architecture gives the underground throne room an almost haunting appearance.

The artwork is especially striking, with intricate details and rich gold accents that contrast with the cold grey stonework. Even the reels resemble carved stone panels, fitting naturally into the surroundings. Rat Royale strikes an excellent balance between dark fantasy and mischievous humour, delivering a visually memorable kingdom where the rats have claimed the crown and apparently have no intention of surrendering it.

Symbols

The lower-paying symbols in Rat Royale feature familiar playing-card ranks 10, J, Q, K and A, presented in ornate gold lettering against a weathered stone background. Winning combinations require at least three matching symbols on consecutive reels, starting from the left. Five matching symbols awarding between 0.3x and 0.6x the stake.

Higher-paying symbols introduce four armoured rats clutching blue, green, purple and red gemstones. These formidable-looking creatures appear ready to defend the royal treasury at any cost, although their loyalty comes with varying rewards. Five matching symbols award between 0.75x and 3x the stake.

Beyond the standard symbols, Wilds substitute for regular paying symbols and have multipliers worth up to 100x. Four coloured Rat King Wilds add extra power, with potential multipliers up to 500x. The Scatters provide access to the Free Spins bonuses. We’ll explore the special symbols in more detail later.

Features

At first glance, Rat Royale doesn’t seem to have many special features, but don’t be fooled. Beneath the straightforward gameplay lies a collection of powerful multipliers, mischievous Rat Kings, and bonus rounds that can turn the royal treasury upside down.

The main attractions are the Wild Symbols, three Free Spins bonuses, and a Feature Buy option in eligible markets. It might seem like a modest line-up compared with some, but these royal rodents have considerably more than meets the eye.

Wilds

The Wild Symbols in Rat Royale have considerably more influence than simply completing winning combinations. Regular Wilds substitute for all paying symbols except Scatters, and five Wilds award 3x the stake.

Standard Wilds land with multipliers of 1x, 2x, 3x, 4x, 5x, 6x, 8x, 10x, 12x, 15x, 25x, 50x or 100x. The multiplier values apply to any winning combination, including a Wild. When multiple Wild multipliers contribute to the same win, their values are added together before calculating the payout.

Things become considerably more interesting when the Rat Kings enter the stage. Appearing exclusively on the third reel, the royal Wilds have multipliers worth 2X, 3X, 4X, 5X, 6X, 8X, 10X, 12X, 15X, 20X, 25X, 50X, 100X, 200X, or 500X. Four coloured Rat King Wilds introduce their own special abilities:

Red Gem Rat King Wild: Expands to cover the entire third reel when one or more winning combinations form. Every Red Rat symbol on the reels receives an additional 1x multiplier.

Purple Gem Rat King Wild: Collects the multiplier values of all regular Wilds on the reels and adds their combined total to its own multiplier.

Green Gem Rat King Wild: Adds its current multiplier value to every regular Wild multiplier on the reels.

Blue Gem Rat King Wild: Transforms all Blue Rat symbols on the reels into a regular Wild Multiplier symbol.

Each Rat King Wild follows the same additive multiplier rules as a standard Wild, so multiple multipliers in one winning combination can produce considerably higher payouts.

Free Spins

The Rat Kings aren’t content with ruling the base game. Rat Royale introduces three Free Spins bonuses, each offering a different level of royal interference. Landing three, four or five Scatter symbols triggers Blood Ritual, Blood Pact or Blood Lust, respectively.

All three bonuses award 10 Free Spins. Landing three or more Scatters during any Free Spin feature awards an additional five spins.

Blood Ritual (3 Scatters): Plays exactly like the base game, but every Wild symbol that lands has a guaranteed multiplier of at least 2x.

Blood Pact (4 Scatters): A Rat King Wild remains in the centre position of the third reel throughout the bonus. On every Free Spin, it receives a randomly selected coloured Gem, determining which of the four Rat King powers trigger. Any multiplier increases persist for the remainder of the feature.

Blood Lust (5 Scatters): The Rat King takes complete control of the third reel, with an expanded Wild occupying all five positions throughout the bonus. A new coloured Gem is randomly assigned on every spin, changing the active Rat King ability. Multiplier increases remain persistent for the duration of the feature.

Rat Royale Special Buys

For players looking to increase their chances of triggering the Free Spins, Rat Royale introduces two Special Bets, otherwise known as Ante Bets. The Ante Bet increase the cost of each spin in exchange for enhanced bonus conditions.

Ante Bet 1 (2.5x the stake): Increases the probability of triggering the Free Spins by 4x compared with the standard game. This option has an RTP of 96.54%.

Ante Bet 2 (5x the stake): Increases the probability of triggering Free Spins and guarantees that every triggered bonus is Blood Lust. The RTP is 96.48%.

Neither option guarantees a Free Spins trigger on any spin.

Rat Royale Feature Buy

Players in eligible international markets can secure an audience with the Rat King with two Feature Buy options. Rather than waiting for the required Scatter symbols, players pay a fixed multiple of their stake to trigger a bonus.

Free Spins (100x the stake): Triggers the standard Free Spins bonus, with an RTP of 96.54%.

Super Free Spins (500x the stake): Triggers the Blood Lust bonus, featuring an expanded Rat King Wild across the third reel. This option has an RTP of 96.52%.

Feature Buy is not available to UK players under Gambling Commission requirements. British players must trigger the Free Spins bonuses through regular gameplay.

Rat Royale Verdict

Pragmatic Play has given the humble sewer rat a remarkable promotion, and Rat Royale certainly looks the part. The magnificent underground lair, imposing Gothic architecture and sinister Rat King create one of Pragmatic’s more memorable fantasy slots. There’s a touch of Game of Thrones about the proceedings, although the question of who deserves the crown has apparently been settled in favour of rodents.

Behind the impressive artwork lies an entertaining feature set. The four Rat King Wilds add ways to increase winning combinations, while Blood Ritual, Blood Pact, and Blood Lust offer progressively more elaborate bonus rounds. Medium volatility is a welcome alternative to the punishing mathematics of many darker-themed slots, although the 15,000x maximum win remains an exceptionally rare prospect.

Rat Royale demonstrates that a slot doesn’t need an endless stream of features to make an impression. The distinctive artwork, innovative Wild mechanics and three Free Spins bonuses give it plenty of character. The rats have claimed the throne, and for once, it’s difficult to argue with their choice of ruler.

Rat Royale is now available at Pragmatic Play casinos, where players can explore the Rat King’s underground kingdom.
