Random Number Generators (RNGs)
Every online casino game outcome is determined by a Random Number Generator — a cryptographic algorithm that produces millions of random numbers per second. When you click "Spin" or "Deal," the RNG's current number determines the outcome.
The sequence is mathematically unpredictable and cannot be influenced by the casino, the player, or external factors. Modern RNGs use algorithms like Mersenne Twister or cryptographically secure PRNGs that have been mathematically proven to produce uniformly distributed random sequences.

How to Verify a Casino's Fairness
- ✅ Look for eCOGRA or iTech Labs certification seals in the casino's footer
- ✅ Check that the casino holds a valid gambling licence from a recognised authority
- ✅ Verify published RTP figures match independent audit reports
- ✅ Read the casino's fairness policy and responsible gambling pages
- ✅ Check player forums and review sites for consistent payout complaints
- ✅ Confirm game providers are licensed and reputable (Pragmatic Play, NetEnt, Evolution, etc.)
Provably Fair Technology
Some crypto casinos like Stake offer provably fair games. This technology uses cryptographic hash functions to let players verify each game result independently. Before each round, the casino commits to a server seed. After the round, players can verify the outcome was genuinely determined by the seed and not manipulated.
This is the most transparent form of fairness verification available — it doesn't require trusting a third-party auditor because players can verify results themselves using mathematical proof.
