Quick answer
An RNG is computer code that makes random numbers to decide game outcomes.
The exact split-second you tap Spin picks the reel stops or card values.
RNG code has no memory of past spins, so every round is fresh and random.
This guide explains RNG math, testing lab audits, and debunks gambling myths.
Key facts:
- Meaning: Random Number Generator (creates fair random spins)
- Memory: Zero memory of past wins or losses
- Auditing labs: BMM Testlabs, GLI
- Where it runs: On the game studio's secure servers
How RNG code works
Casino games use secure random number math:
1. The RNG runs non-stop, making thousands of numbers every second.
2. When you tap Spin, the game grabs the current number at that millisecond.
3. The game turns that number into matching reel symbols.
4. The spinning screen simply shows the result that was already picked.
Common casino myths debunked
Knowing RNG math clears up common false beliefs:
| False Belief | The Real Fact | Why It Is True |
|---|---|---|
| "This slot is due to win" | False | The RNG has no memory; each spin has the exact same odds. |
| "A slot runs cold after a win" | False | Winning once does not lower your odds on the next spin. |
| "Casinos change odds at night" | False | Math runs on studio servers; casinos cannot edit odds. |
| "Demo mode pays more than real money" | False | Real studios use the exact same RNG code for both modes. |
Outside testing lab checks
Before games can launch, their RNG code must pass tests:
- BMM Testlabs: Oldest independent game testing lab in the world.
- GLI: Global leader in gaming checks.
Labs test millions of practice spins to confirm that games pay fair results.

### Does spin timing matter?
Yes. The RNG makes numbers non-stop, so tapping spin a millisecond later gets a different seed.
### Are live dealer games run by RNG?
Live tables use real physical cards and wheels, though game shows use RNG for extra multipliers.
