Pragmatic Play UK: Gates of Olympus, Big Bass Bonanza and Best Casinos in 2026

Gates of Olympus, Big Bass Bonanza, and Sweet Bonanza are some of the most-played online slots in the UK market right now – and they are all Pragmatic Play games. If you have opened a casino app in the past three years, you have almost certainly played Pragmatic Play content, whether you noticed the studio name or not.

Pragmatic Play launched in 2015 following a rebrand from an earlier studio (TopGame) and today operates as a fully UKGC-licensed provider with more than 2,000 casino partners worldwide. The catalogue runs to 300+ slots and 500+ titles across slots, live casino, crash games, bingo, and virtual sports. The release pace is the highest of any mainstream studio offering games in the UK, and through Drops and Wins, they run the most widely distributed network prize promotion in the industry.

This page covers the games that are actually worth your time, organised by slot series so you can find related titles to suit your given play style. It also provides details on how the Drops and Wins promotion works in practice, what Pragmatic Play Live offers, and which five UK casinos give you the best access to the Pragmatic Play games portfolio.

Every major UK slot studio is covered in the UK casino software hub, highlighting where Pragmatic Play sits alongside the full market comparison.

Pragmatic Play is not the highest-RTP studio in the market. That distinction belongs to NetEnt (Blood Suckers at 98%). It is also not the most franchise-driven studio. That title can be attributed to the likes of Play'n Go with its Rich Wilde slot series. But what Pragmatic Play does do, is operate at scale across every gambling vertical simultaneously, alongside a network promotion that benefits players at participating casinos, every month.

Pragmatic Play releases multiple new games per week across slots, live casino, crash games, bingo, and virtual sports. Few mainstream studios match this release pace while maintaining catalogue quality. Most players will be familiar with Pragmatic’s flagship series of slots, namely Big Bass, Gates of Olympus, and Sweet Bonanza which represent the studio at its best. For players who prioritise RTP consistency over volume, studios like NetEnt takes a very different approach, with a smaller catalogue being built around higher and more consistent long-run returns.

No other studio runs a cross-casino network promotion at the scale of Pragmatic Play’s Drops and Wins. A monthly prize pool of over 1,000,000 EUR is distributed across slots and live casino games at every participating Pragmatic Play casino simultaneously. Players do not need to opt in, register for a special promotion, or change how they play. Simply playing any Drops and Wins associated game on a qualifying spin makes you eligible for both random Prize Drops and Tournament leaderboard prizes. This is covered in its own section below.

Pragmatic Play Live is not part of the Evolution Group, it operates its own independent live dealer studios. For players who want variety beyond Evolution's tables, Pragmatic Play Live offers One Blackjack (unlimited players, same mechanic as Evolution's Infinite Blackjack), Mega Roulette 3000 (random multipliers up to 3,000x, comparable to Lightning Roulette but with a higher multiplier ceiling), and Money Time (a game show format with up to 40,000x potential).

Before playing any Pragmatic Play game at a casino you have not used before tap or click the information icon (marked (i)) in the game interface. The RTP shown there is the version that the specific casino is running. If it differs significantly from the standard figure listed in this guide, that casino has chosen to implement a lower-return version.

• Gates of Olympus standard RTP: 96.50%. At some casinos: 95.51%. Check before playing.
• Sweet Bonanza standard RTP: 96.51%. Varies at some operators. Check before playing.
• Big Bass Bonanza standard RTP: 96.71%. The highest flagship RTP in the catalogue; most casinos run the standard version, but the check is still worth doing.

This is not a criticism of Pragmatic Play, as their published RTPs are independently certified for the standard version. It’s an industry-wide practice, and the information is always available in the game itself. Checking the long-run mathematical return before your first spin takes ten seconds and can meaningfully affect your choice of casino.

The table below covers  ten popular Pragmatic Play titles ranked by RTP from highest to lowest. The slot series’ breakdowns give context to what each franchise is designed for, how the mechanics differ, and where to start. All are amongst the most-played UK online slots  of today.

Big Bass Bonanza (2020) is the best-returning flagship game in the Pragmatic Play catalogue at 96.71% RTP, and the most accessible for players who find Gates of Olympus too volatile. The mechanic is built around a Fisherman Wild symbol that collects fish cash symbols and adds their values to a combined prize when the feature lands. It is not a complicated game. What it does well is deliver bonus rounds at a rate that most high-volatility slots cannot match: Big Bass Splash, the aquatic sequel, triggers a bonus approximately once every 113 spins, which is among the highest frequencies in any major series.

For players new to Pragmatic Play slots, Big Bass Bonanza or Big Bass Splash  offer a great starting point. With lower  volatility ratings than the Olympus titles, these games experience the bonus features more often. The series has since expanded to include Big Bass Hold and Spinner, Big Bass Day at the Races, and Big Bass Vegas Double Down Deluxe – enough options to keep a Big Bass player occupied for a long time.

Big Bass Bonanza and Big Bass Splash are both commonly featured in free spins welcome offers across UK casinos. Current offers by casinos are tracked in the UK free spins guide.

Gates of Olympus is the most globally recognised Pragmatic Play slot and the one most frequently cited when players describe the studio. The 6x5 grid uses cluster pays rather than traditional paylines: wins form from groups of eight or more matching symbols touching horizontally or vertically. During free spins, Zeus can strike the grid at any point to apply random multipliers of up to 500x. These multipliers stack, and a sequence where several 500x multipliers hit consecutively against a large cluster win is how the 5,000x maximum is reached.

The standard RTP of 96.50% applies to most versions. This is the game where the RTP variation issue is most practically significant: the gap between 96.50% and 95.51% is larger in real terms than it sounds, and the (i) screen in the game will show you exactly which version your casino is running.

Gates of Olympus 1000 uses the same base mechanic but raises the maximum win to 15,000x through a higher-variance setup. The boosted ceiling comes with sessions that can feel more barren before you land any features. Gates of Hades takes the same cluster-pays grid into an underworld setting, with Hades replacing Zeus as the deity applying random multipliers. The two variants suit different players: 1000 for those chasing the highest ceiling; Hades for those who want a thematic change without altering the core format.

Sweet Bonanza (2019) was the game that established the tumble mechanic as a mainstream format in UK online slots. The 6x5 grid pays on scatter clusters rather than adjacent symbols. Winning symbols are removed and replaced by new ones cascading from above, extending winning sequences. In the free spins feature, multiplier bomb symbols can apply stackable multipliers of up to 100x to your wins, which is how the 21,100x maximum becomes theoretically possible. The candy theme is immediately accessible, and the mechanic is intuitive enough that it works as a gateway to cluster-pays formats for players who have only played payline slots.

Sugar Rush follows the same structural logic with a collecting mechanic: diamond scatters accumulate and apply their total as a multiplier during free spins. Starlight Princess uses an 8x8 grid with an anime aesthetic, the obvious pick for players who enjoy Play'n Go's Moon Princess but want to transition to Pragmatic Play. The 1000 series applies boosted maximum wins to the same base mechanics, with adjusted pay tables enabling the higher outcomes. For players who have played the originals and want more upside with greater session variance, the 1000 series is the logical step up.

The Dog House (2019) uses a 5x3 layout with sticky wilds and multipliers up to 9x in free spins. The tone is lighter and the mechanics are more conventional than the Olympus cluster-pays games, making it a useful middle-ground for players who want lower-variance Pragmatic Play titles. The Dog House Megaways applies the BTG Megaways engine (up to 117,649 ways to win) to the same theme.

Pragmatic Play Live operates its own independent studios outside the Evolution Group. One Blackjack runs at approximately 99% RTP with optimal strategy and uses the same concept as Evolution's Infinite Blackjack. Mega Roulette 3000 applies multipliers of up to 3,000x to any number, a higher ceiling than Lightning Roulette's 500x (though the base RTP is comparatively lower). Money Time is a game show format with a 40,000x prize ceiling. For live casino players who have only used Evolution tables, Pragmatic Play Live adds real variety.

Drops and Wins is the single most significant reason to actively choose a Pragmatic Play casino over one that only carries Evolution or NetEnt games. It is a monthly prize pool network promotion that distributes over 1,000,000 EUR every month via two separate mechanics, and unlike most welcome bonuses, it requires no opt-in and carries no wagering requirement of its own.

Selected Pragmatic Play games at participating casinos run leaderboard competitions over set time periods. Players accumulate points based on qualifying spins during the tournament window. At the end of the window, the top finishers on the leaderboard share cash prizes from the prize pool. There is no registration, no opt-in, and no change to normal gameplay required; simply playing a tournament eligible game accumulates points automatically.

Separately from the tournament leaderboards, Prize Drop cash prizes can be won at random on any qualifying spin during the promotion period. Any player on any eligible game at any participating casino has a chance at a Prize Drop win when wagering £0.15 or more. There is no strategy that increases your chances beyond playing eligible games; the drops are genuinely random.

Drops and Wins-eligible games are marked with a badge in the casino lobby. The specific games included in each promotion period change, so the badge is the most reliable indicator. At casinos with a good lobby filter (Kwiff, JackpotCity), you can filter by the promotion to see every eligible game at once.

All five casinos below have confirmed Pragmatic Play carrier status. The ordering reflects the strength of each casino's Pragmatic Play-specific proposition rather than overall casino quality.

Pragmatic Play is one of the most universally available studios at UK-licensed casinos. The provider filter in most UK casino lobbies will return results immediately. Search 'Pragmatic Play' rather than 'PP' or any abbreviation.

• Drops and Wins eligible games: look for the Drops and Wins badge in the lobby. These are the games currently running in the monthly promotion period. Or, use the game search bar to filter by ‘Drops and Wins’ to see all eligible titles at once.
• Live casino: Pragmatic Play Live tables appear in the live casino section, not in the slots filter. Search 'Pragmatic Play' or 'Pragmatic Play Live' in the live lobby. Not all casinos label Pragmatic Play Live separately from other live providers.

Pragmatic Play holds a UKGC licence, an MGA (Malta Gaming Authority) licence, and licences across 40+ regulated jurisdictions globally. Games are independently tested by three laboratories: eCOGRA, GLI, and BMM Testlabs, so you can be sure that the advertised RTP figures are verified. Every UK-licensed casino carrying Pragmatic Play games is subject to the same UKGC standards at the operator level.

Pragmatic Play launched in 2015 following the rebrand of TopGame Technology (2007), shifting the business entirely to regulated, licensed markets. The current operation is under UKGC oversight, with all games independently audited. 

The Bonus Buy feature, which allows players to purchase direct access to a game's free spins round, is disabled on all Pragmatic Play slots for UK players under UKGC rules. This applies market-wide. You may see screenshots of the feature in international reviews, but it will not appear at any UKGC-licensed casino.
