The UK online slots market includes thousands of games available across licensed online casino platforms. Among them, Gates of Olympus and the Big Bass series are two well-known titles developed by Pragmatic Play studios and widely available through UK-licensed operators.
Although both belong to the online slots category, they use different gameplay mechanics, bonus structures, and payout systems. Comparing these differences provides insight into how modern slot design has evolved beyond traditional fixed-payline formats.
Comparing the Core Mechanics
Traditional slot machines rely on fixed paylines, where matching symbols must land on designated lines across the reels to produce a winning combination.
Many modern online slots use alternative systems. The Gates of Olympus and the Big Bass series both incorporate bonus elements, although each does so through a distinct gameplay structure.
Gates of Olympus and the Scatter Pays System
Gates of Olympus replaces traditional paylines with a Scatter Pays system. Under this model, winning combinations are formed according to the game’s rules rather than fixed paylines. Matching symbols can contribute to payouts regardless of their exact reel position.
The game also uses cascading reels. When a qualifying combination occurs, the winning symbols disappear, and new symbols fall into their place. This can create additional qualifying combinations during the same spin.
Multiplier symbols may also appear during gameplay and apply values according to the game’s rules, particularly during bonus features.
The Big Bass Series and Collection Features
The Big Bass franchise includes several titles, including Big Bass Bonanza, Big Bass Splash, and Big Bass Floats My Boat.
Most games in the series follow a collection-based feature system alongside standard reel gameplay. Certain symbols trigger bonus rounds, while others contribute towards feature progression during those rounds. Depending on the title, additional stages or modified bonus rules may also be included.
Although individual releases can vary, the fundamental gameplay framework continues to focus on collection mechanisms instead of progressive reels.
Side-by-Side Structural Comparison

Volatility and Gameplay Structure
In addition to different bonus systems, the two game formats also differ in volatility. Volatility is separate from a game’s Return to Player (RTP) percentage. RTP represents the theoretical percentage of total stakes that a game is expected to return to players over a very large number of spins, and volatility describes how those returns are typically distributed.
Gates of Olympus is generally classified as a very high-volatility slot, meaning larger wins may occur less frequently over extended play. Most Big Bass titles are classified as medium to high volatility, although classifications may vary between individual releases.
Mobile Compatibility and Game Design
As online gambling has expanded across mobile devices, developers have increasingly designed slot games to function consistently across desktop computers, smartphones, and tablets.
Gates of Olympus uses a 6×5 reel layout that adjusts to different screen sizes while maintaining the same gameplay structure. The Big Bass series also uses layouts designed to display symbols, menus, and feature information clearly across supported devices.
What These Games Show About Modern Slot Design
Gates of Olympus and the Big Bass series show how online slot development has moved beyond traditional fixed-payline machines. Many modern slots have various payout systems, progressive features, and bonus mechanisms. They don’t solely depend on reel combinations.
Although the two game formats use different technical approaches, they illustrate broader trends in contemporary online slot development, where developers continue to experiment with different gameplay structures while remaining within regulated gaming frameworks.
Responsible Gambling
Gambling should be viewed as a form of entertainment rather than a way to make money. Anyone gambling online in Great Britain should check that the operator is licensed by the UK Gambling Commission, using its public register where necessary. Licensed operators must provide safer gambling information and access to tools such as deposit limits, time-outs, and self-exclusion. Those concerned about their own or someone else’s gambling can seek confidential support through GamCare and the National Gambling Helpline.
