Online casino games often look identical at first glance, but the software behind them can be very different. A genuine (legally supplied) game is distributed under contract, tested by approved labs, and delivered in a controlled way. A clone is a copied build that mimics the visuals while changing maths, payouts, or even injecting malware. In 2026, recognising the difference is a practical skill for both players and operators.
Genuine casino games are supplied by an identifiable studio (the provider) through a licensed operator, usually via a direct integration or an aggregator. The game will have consistent branding, a stable game ID/version, and clear in-game information (rules, paytable, RTP statement where required, and responsible gambling links). It is normal to see a provider logo, an “info” button, and legally required disclosures that match the operator’s licensed markets.
A key difference is that real suppliers operate under technical and legal controls. Builds are versioned, changes are tracked, and releases follow change-management procedures, because regulators and test houses can require evidence of what was deployed and when. That “paper trail” matters: it is hard to fake consistently across updates, jurisdictions, and language packs.
Finally, genuine games are typically connected to independent testing. You will not always see a certificate inside the game window, but the operator’s compliance area (or licence page) often references independent testing and approved test houses. If a casino claims “tested RNG” but cannot name a lab or show any compliance references anywhere on the site, that is a warning sign.
In regulated markets, game fairness is assessed through technical standards: randomness (RNG behaviour), payout calculations, game rules, and integrity controls. Independent labs such as eCOGRA, iTech Labs, and GLI are widely used for testing and certification work. A genuine supply chain relies on these checks because licensing frameworks expect third-party testing to support compliance.
For players, the practical takeaway is simple: testing does not guarantee you will win, but it reduces the risk that outcomes are manipulated or that payout logic has been altered. Clones frequently change the “math model” while keeping visuals the same, because visuals are what most people notice first. Certification makes silent changes harder to hide over time.
For operators, independent testing also supports incident response. If a game update triggers abnormal behaviour, logs, version history, and previous test results provide a baseline. With cloned software there is no trustworthy baseline, and you cannot reliably prove to a regulator (or to players) what is running.
Clones often reveal themselves through small inconsistencies. Common tells include mismatched provider branding (logo present but not clickable or spelled differently), missing or oddly written rules, paytables that do not match the symbols, and RTP statements that look generic. Another frequent issue is language quality: real providers localise carefully, while copied builds often contain awkward phrasing, mixed spelling standards, or broken formatting inside the help screens.
Performance and behaviour can also be a clue. If a game loads unusually slowly, reloads mid-spin, shows flickering overlays, or behaves differently across devices in a way that feels “unfinished”, treat it cautiously. Genuine releases are not perfect, but providers have QA processes because defects cost them money and licensing opportunities. Cloners optimise for speed of copying, not stability.
Payment or session behaviour is an underappreciated sign. If your balance display updates strangely, if there is a delay between spin results and balance changes, or if the game disconnects precisely after a feature round, you may be looking at a poorly implemented copy or a build that is intercepting data. Even if the casino itself looks polished, a single bad game integration is enough to create risk.
Start with the provider list and the operator’s licence details. Regulated operators usually present licensing information clearly and tend to carry well-known suppliers because those suppliers bring their own compliance expectations. If a casino claims dozens of famous providers but none of them are linked, named consistently, or visible inside the games, be sceptical.
Use the game’s information button. Genuine games normally contain structured rules, paylines/ways, feature descriptions, and sometimes version/build identifiers. If the “help” section is missing, ultra-short, or written in a way that does not match the provider’s usual style, that is a practical clue that something is off.
Finally, cross-check the same title elsewhere. If you can find the same game at a well-known licensed operator and the game presentation (symbols, bonus rules, buy-feature options, paylines/ways) is different, assume the weaker version is the suspect one. Clones often copy art but get the mechanics wrong.

If you are comfortable with basic technical checks, look at where the game assets are loaded from. In a browser, developer tools can show the domains serving the game client and resources. Genuine supply chains often use recognisable provider or aggregator domains and consistent file structures. Clones frequently use generic hosting with random paths that change often, because they are trying to stay mobile.
Operators should go further: require contractual proof of rights to distribute, obtain RNG and game certificates from recognised test houses, and maintain a deployment register (what version, when deployed, who approved). In 2026, this is not “extra bureaucracy”; it is how you prove integrity when there is a dispute or a regulator query.
Also pay attention to update discipline. Real providers ship patch notes, version increments, and sometimes jurisdiction-specific configurations. A suspicious sign is a library of “famous” games that never updates, never changes, and never shows seasonal releases that the real provider is actively promoting. Stagnant game libraries can be a sign of copied builds that cannot be safely updated.
Regulators and compliance frameworks push operators towards controlled third-party testing and documented processes. The UK Gambling Commission, for example, publishes technical standards and a testing strategy that relies on third-party testing with approved test houses. That structure makes it difficult (though not impossible) for cloned software to survive in properly regulated environments.
The Malta Gaming Authority also expects documentation and approvals when adding game providers and related third-party agreements. In practice, this forces operators to treat game providers as audited suppliers rather than anonymous content sources. Cloned software typically cannot provide verifiable supplier documentation, so it tends to cluster in weaker regulatory environments or in unlicensed brands.
For players, this translates into a practical rule: the more transparent the operator is about licensing, testing, and supplier relationships, the lower the probability you are dealing with copied games. Transparency does not guarantee safety, but secrecy nearly always increases risk.
