RNG & Fairness
Understanding how Random Number Generators ensure fair casino games at 1xBet.
Last updated: January 22, 2026
What is RNG?
A Random Number Generator (RNG) is a computer algorithm that produces unpredictable numbers used to determine game outcomes.
How RNG Works
- Seed generation — Initial random value created from multiple sources
- Algorithm processing — Cryptographic function generates numbers
- Number mapping — Numbers converted to game outcomes (cards, symbols)
- Result display — Outcome shown to player
Types of RNG
| Type | Description | Used For |
|---|---|---|
| PRNG | Pseudo-Random Number Generator (algorithm-based) | Most casino games |
| TRNG | True Random (hardware/physical sources) | Seed generation |
| CSPRNG | Cryptographically Secure PRNG | Security-critical games |
RNG Certification
1xBet's game providers use RNGs tested and certified by independent laboratories:
| Testing Lab | What They Test |
|---|---|
| eCOGRA | RNG fairness, payout percentages |
| iTech Labs | Game mathematics, RNG compliance |
| GLI (Gaming Labs) | Regulatory compliance, RNG testing |
| BMM Testlabs | Game testing, RNG certification |
What Testing Verifies
- Randomness: Results are statistically random
- Unpredictability: Cannot predict next outcome
- Non-repeatability: No patterns in sequences
- Independence: Each result independent of others
- Fairness: Actual RTP matches stated RTP
Return to Player (RTP)
RTP is the percentage of wagered money a game returns to players over time.
| Game Type | Typical RTP | House Edge |
|---|---|---|
| Slots | 94-98% | 2-6% |
| Blackjack | 99%+ | <1% |
| Roulette (European) | 97.3% | 2.7% |
| Baccarat | 98.9% | 1.1% |
| Video Poker | 97-99% | 1-3% |
Provably Fair Games
Some games allow you to verify fairness yourself:
How Provably Fair Works
- Server seed — Casino generates secret seed (hashed)
- Client seed — You can provide your own seed
- Game played — Result determined by both seeds
- Verification — After game, seeds revealed for verification
This cryptographic system ensures the casino cannot manipulate results after you place a bet.
Common Myths Debunked
"The game is due for a win"
False. Each spin/hand is independent. Previous results don't affect future outcomes. A slot that hasn't paid out is not "due" — it has the same odds every spin.
"Casinos can flip a switch to stop wins"
False. RNG results are determined instantly when you click. The casino cannot see or change results. Certified RNGs prevent manipulation.
"Playing at certain times increases chances"
False. RNGs don't know what time it is. Odds are identical 24/7. There's no "hot" or "cold" time to play.
"Bet size affects win probability"
False. The RNG doesn't know your bet size when generating results. A $1 spin has the same win percentage as a $100 spin.
"New accounts win more"
False. RNGs don't track account age. New and old accounts have identical odds on every game.
Understanding Variance
Variance (volatility) explains why short-term results differ from RTP:
| Variance | Characteristics | Experience |
|---|---|---|
| Low | Frequent small wins | Steady, longer play sessions |
| Medium | Balanced wins | Mix of small and bigger wins |
| High | Rare big wins | Long dry spells, occasional jackpots |
High variance games can create the illusion of being "rigged" during losing streaks, but they're working exactly as designed.
