Is Big Bass Bonanza Legit?
Big Bass Bonanza is a fully licensed slot game developed by Pragmatic Play, one of the largest game studios in the industry. Here is how you can verify that for yourself.
Pragmatic Play – The Developer
Big Bass Bonanza is made by Pragmatic Play, a game studio headquartered in Malta that supplies slots, live casino games and bingo products to casinos worldwide. Pragmatic Play is not a small or obscure outfit – the company holds gambling licences in over 20 regulated markets, employs more than 8,000 people, and its games appear in the lobbies of most major online casinos.
Pragmatic Play’s parent company, Pragmatic Group, is a well-established entity in the iGaming sector. The studio releases multiple new titles every month, and its portfolio includes widely recognised games beyond the Big Bass series – titles like The Dog House, Gates of Olympus and Sweet Bonanza are among the most played online slots globally.
The company’s scale matters because operating at that level requires maintaining licences across multiple jurisdictions, each with its own compliance requirements. A studio that cuts corners on fairness does not survive long-term scrutiny from regulators in Ireland, Malta, Gibraltar, Sweden and dozens of other markets simultaneously.
RNG Certification and Independent Testing
Every outcome in Big Bass Bonanza is determined by a Random Number Generator (RNG) – a mathematical algorithm that produces unpredictable results on every spin. The RNG does not know or care whether you have just won or lost, how much you have wagered, or how long you have been playing. Each spin is an independent event.
Pragmatic Play’s RNG systems are tested and certified by independent testing laboratories. These labs, such as BMM Testlabs and Gaming Laboratories International (GLI), audit the game’s source code to verify that the RNG produces genuinely random results and that the game’s actual return-to-player percentage matches what is advertised. The testing process involves running millions of simulated spins and analysing the statistical distribution of outcomes.
This is not a one-off check. Regulators require ongoing compliance, and Pragmatic Play’s systems are subject to periodic re-testing. The certification applies to the game’s core logic – the same RNG engine runs regardless of which casino you play at.
UKGC Licensing
Every casino listed on this site holds a licence from the Malta Gaming Authority (UKGC), which is the regulatory body responsible for overseeing all commercial gambling in Great Britain. A UKGC licence is not easy to obtain or maintain – operators must demonstrate that their games are fair, that player funds are segregated and protected, and that responsible gambling measures are in place.
Pragmatic Play itself holds UKGC licence number 46683, which authorises the company to supply games to British operators. This means Big Bass Bonanza has been approved by the Commission as suitable for the UK market. If you play at a UKGC-licensed casino, you are protected by British gambling law, which includes:
- Mandatory fair game testing and RNG certification
- Separation of player funds from operating funds
- Access to an independent dispute resolution service (ADR)
- Strict advertising standards and age verification requirements
- Self-exclusion tools and deposit limits
You can verify any casino’s UKGC licence by searching the Gambling Commission’s public register. Our casino listings include only UKGC-licensed operators.
RTP Transparency
Big Bass Bonanza displays its Return to Player (RTP) percentage directly within the game. You can find it by tapping the “i” button (or menu icon on mobile) to open the game information screen, then navigating to the rules or paytable section. The RTP represents the theoretical percentage of all wagered money that the game returns to players over millions of spins.
| Default RTP | 96.71% |
| Where to check | In-game info screen (“i” button) |
| Type | Theoretical, calculated over millions of spins |
| Verified by | Independent testing laboratories |
The fact that this information is accessible inside the game itself is a regulatory requirement. Pragmatic Play cannot hide or misrepresent the RTP – doing so would violate their licence conditions in every jurisdiction they operate in. What you see in the info screen is the actual configured RTP for that particular casino.
Multiple RTP Versions Explained
One detail that sometimes causes confusion is that Big Bass Bonanza exists in multiple RTP configurations. Pragmatic Play makes the game available with several RTP options, and each casino operator chooses which version to run. The most common versions are:
- 96.71% – the default and most widely used version
- 96.07% – a slightly lower variant some operators select
- 95.67% and lower – reduced RTP versions available in certain markets
This is standard practice across the slot industry and is not unique to Big Bass Bonanza or Pragmatic Play. The important point is that whichever version a casino uses, it must be displayed in the game’s info screen. You can always check before you play – open the game, tap the “i” or menu button, and look for the RTP figure in the rules section.
The difference between 96.71% and 95.67% is roughly one extra pound lost per hundred pounds wagered over the long run. It is worth checking, but it does not change the fundamental legitimacy of the game – all versions are independently tested and certified.

The Short Answer
Big Bass Bonanza is a legitimate, independently tested slot game made by one of the largest studios in the industry. It uses a certified RNG, displays its RTP transparently, and is available exclusively through licensed operators on this site. The game itself is not rigged – it is a high-volatility slot, which means results are streaky by design, but the maths behind it are verified by third-party labs and enforced by regulators.
