The casino is the storefront. The games come from elsewhere. Knowing the supply chain helps you understand why two casinos can offer the same slot at the same RTP.
Who builds the games
Studios like NetEnt, Pragmatic Play, Play’n GO, Hacksaw Gaming, Evolution, and Big Time Gaming design, develop, and host their own games. Many smaller studios distribute through aggregators.
What the casino does
Operators license a game library from each provider (or through an aggregator), integrate the API, and offer the games inside their lobby. They do not control the maths or the outcomes.
Certification and testing
In the UK, every game must be tested by an accredited lab — GLI, iTech Labs, eCOGRA. The RTP and RNG are audited before launch and re-tested periodically.
Why this matters for players
- The same slot has the same maths across casinos (with rare exceptions where multiple RTP versions exist — always check the in-game info screen).
- A trusted provider name on a game is a strong signal of fairness.
- Bugs, glitches, or disputed payouts are usually resolved between casino and provider, with the casino as the player’s contact point.
